The present invention relates to detergent compositions that can be used for hard surfaces and particularly for cleaning floors (decks), including common applications and devices, such as sponge, cloth, MOP with a sponge MOP from ropes, tape mops and sexual rags. This application is also particularly useful with "replaceable" purifying device containing overabsorbed material for the removal of contaminants tetudou pillow, preferably constructed so as to provide multiple cleaning surfaces.

In the literature revealed many products that can clean hard surfaces, such as floors (decks) of ceramic flooring (flooring) wood of firm breeds, the upper surface of the shelves and the like. In connection with cleanable floors (decks) described numerous devices containing the handle and some means to absorb liquid cleansing composition. Such devices include those that are reusable, including mops, containing cotton rope, cellulose and/or synthetic tape, sponges and the like. The use of any such device or MOP requires considerable effort.

Examples of the replaceable MOP include: U.S. patent 5094559 issued Rivera and others on March 10, 1992, which describes a MOP, which incorporates a replaceable cleaning pad, containing scraping the layer to remove dirt from a contaminated surface of the absorbent (absorbent) layer for absorption of the liquid after the cleaning process and impermeable to the liquid layer disposed between scraping and absorbent layers, and U.S. patent 5419015 issued Garcia on may 30, 1995, which preferably contains a removable cleaning pad, that alleviates the need to propulsive pillow during use. This cleansing pillow preferably has sufficient absorptive capacity, grams of absorbed liquid per gram basis cleansing pillows to provide treatment of a large area, such as area of usual floor with a hard surface (for example, 7,4-9.3 m2), without having to replace the pillows. This usually requires the use of overabsorbed material preferably of the type disclosed hereinafter. Detergent composition, which is used with such overabsorbed materials must be carefully drafted to avoid the failure in achieving the purpose for which such overabsorbed material is used.

Preferred cleaning equipment have a pillow that shows useful properties remove dirt, thanks to the continuous provision of fresh surface and/or edge for contact with the contaminated surface, for example, by providing a variety of surfaces that come into contact with contaminated surface during cleaning operations.

Detergent compositions used for cleaning hard surfaces, such as floors (decks), or undiluted the second substance, the modifying additive, a solvent, etc. to enable the solution to provide excellent final cleaning without causing accumulation or stickiness. End use based on what the product is intended for use: dilute, such as in the case of cleaning products for floors and multi-purpose cleaners, or undiluted, such as in the case of sprays from a bottle or spray of cleaning supplies MOP used with a removable or reusable pillows.

Typically, the cleaning solution "end use" or undiluted, or diluted, contains less than about 0.5% by weight solution of detergent surfactants. The concentration of detergent surfactant in the cleaning solution, the final application is preferably from about 0.01% to about 0.5%, more preferably from about 0.05% to about 0.4% and even more preferably from about 0.05% to about 0.3% by weight of the composition/treatment solution. To improve the purification may also be present one or more cleaning solvents, preferably hydrophobic cleaning solvents. The concentration of RNO is from about 0.1% to about 5.0 percent, more preferably from about 0.25% to about 4.0% and even more preferably from about 0.5% to about 3.0 percent by weight of the composition/treatment solution.

To facilitate cleaning with conventional accessories, such as tissue, sponges and mops, such as mops sponges, tape or rope, and to avoid the difficulties of absorption when using the pillow containing overabsorbed materials, the pH is preferably more than about 9, more preferably more than about 9.5, and more preferably more than about 10. Alkalinity should be preferably provided, at least partially, volatile materials, to avoid the problems associated with the formation of bands/films.

To help the alignment of the solution during drying the composition should contain a polymer that is hydrophilic properties and properties of dilute shear, that is able to inhibit the molecular aggregation solution of surface-active substances on the floor during the drying process, to provide one or more useful properties, such as the ability to remove from the surface (Shimamoto), the exception accumulation, easy distribution of the solution on a solid gradienty, remaining on the surface. Under the "alignment" refers to minimizing bleed solution from the surface during drying, which, in turn, minimizes the formation of bands. Thanks to this useful property of the polymer allows to obtain the compound, even at low concentrations of surfactant and allows the addition of solvents to facilitate cleaning without education films/strips. Generally, this can also lead to the reduction of residue on the surface and sticky floors.

The desired polymer is preferably present only at very low concentrations, i.e. from about 0,0001% to about 0.2%, preferably from about 0,0001% to about 0.1%, more preferably from about 0,0005% to around 0.08% by weight of the cleaning solution. The concentration of the product will reflect the type of application, in undiluted or diluted form. The polymer is preferably chosen from the group consisting of natural resins, especially xanthan gums, guar gum, Arabic gum and/or pectins; synthetic polymers such as poly(styrelseledamot), poly(vinyl pyrrolidone); and mixtures thereof as monomers and/or polymers. Most preferred is xanthan gum.

physical rehabilitation group should not be present, and detergent surfactant is preferably relatively water-soluble, for example, having a hydrophobic chain containing from about 8 to about 14, preferably from about 8 to about 12 carbon atoms, and, for the nonionic detergent surfactants having the products HLB from about 9 to about 14, preferably from about 10 to about 13, more preferably from about 10 to about 12.

The composition may be used in connection with conventional solid surface, such as cleaning products for floor or multi-purpose cleaners, and with regular cleaning systems and/or systems for cleaning MOP, known from the prior art, such as sponge and fabric, such as a MOP with a sponge MOP from ropes, tape mops and sexual rags. In addition, a preferred aspect of this invention relates to the use of cleaning solutions/compounds fixture all-in-one plus system cleansing pillows. Cleansing pillow preferably contains overabsorbed material and works synergistically with the described detergent composition/solution to ensure a better final cleaning with great convenience. This cleansing system usually contains the handle and replaceable (adlergestell, where each of the essentially flat surfaces in contact with the surface being cleaned, and the preferred structure of the cushion, which has both the first layer and the second layer, where the first layer is placed between the scraping layer and the second layer and has a smaller width than the second layer.

Depending on the means used to attach the cleaning of pillows to handle cleaning equipment, it may be preferable to cleansing pillow additionally contained special anchoring layer. In these variants of the embodiment, the layer of absorbent material must be placed between the scraping layer and the anchoring layer.

Detergent composition and, preferably, the device of the present invention are compatible with all substrates of hard surfaces, including wood, vinyl, linoleum, unwaxed floors, ceramics, Formica, porcelain, glass, wallboard and the like. Device and detergent composition easy to clean, especially when present in the polymer, to provide for easier cleaning MOP, and more good results.

DETERGENT COMPOSITION

Detergent composition acts as a cleaning solution, or when it is used undiluted, or when it is diluted. The composition is obtained by dilution before use, a more concentrated product with water in a ratio of from 1: 50 to 1:250 parts of water/part composition. Therefore, the concentration of ingredients should be considered in the context of the final application. The desired polymer is used only at very low concentrations in the cleaning solution. Therefore, any concentrated composition should be Packed in the concentration of the polymer should be low for example be from about 0,0001% to about 0.2%, preferably from about 0,0001% to about 0.1%, more preferably from about 0,0005% to around 0.08% by weight of the composition. This very low concentration is all that is required to get a better final cleaning, higher concentrations can cause the formation of bands/films, accumulation and/or stickiness.

Not wanting to be limited by theory, is considered critical for two polymer physical properties: hydrophilic nature and the ability dilution shear. The hydrophilicity of the polymer is important to ensure the ability to remove (removal) in the periods between each execution, to avoid accumulation. Property dilution shear is important to facilitate uniform distribution of the solution when used in combination with hydrophilic characteristics helps ensure the alignment effect. Under the "alignment effect" refers to minimizing sweating solution and molecular aggregation that usually occurs during drying. Molecular aggregation leads to visible bands/films, which is a sign of bad final cleanup.

Suitable examples of polymers include cellulosic materials, the e as polystyrenesulfonate. Most preferred are naturally occurring polymers, such as the Arabian gum, pectin, guar gum and xanthan gum. Most preferred is xanthan gum. Xanthan gum is disclosed in U.S. patent 4788006 issued Bolich November 29, 1986, in column 5, line 55 to column 6, line 2. Many synthetic polymers can provide this beneficial effect, especially polymers, which contain hydrophilic groups, such as carboxylate groups. Other polymers that can provide thinning shear and hydrophilicity include cationic materials, which also contain hydrophilic groups, and polymers that contain multiple ether linkages. Cationic materials include cationic derivatives of sugar and/or starch.

The preferred polymers are those that have a higher molecular weight, although the molecular weight of up to about 5000 can provide some results. In General, the polymers should have a molecular weight of more than about 10,000, preferably more than about 100,000, more preferably more than about 250,000, and even more preferably more than about 500,000. The molecular weight is typically Dolin to about 4000000 and even more preferably more than 4000000.

Examples of suitable materials for use include polymers, preferably selected from the group consisting of xanthan gums, guar gum, Arabic gum, pectin, poly(styrelseledamot) and their mixtures of monomers and/or polymers. These polymers can also be used in combination with polymers that do not provide useful effect or provide this effect to a lesser extent, to achieve improved final cleaning. Most preferred is xanthan gum.

Used polymer preferably is a polymer that provides a thinning shear, especially to facilitate distribution. Compounds that have the property of dilution shear, can be used undiluted without modification. Liquid detergent composition for hard surfaces and particularly preferred detergent compositions described herein should have a viscosity less than about 250 centipoise, preferably less than about 100 centipoise, and even more preferably less than about 15 centipoise. The viscosity is determined using singleelectron a Brookfield viscometer, model LVT, manufactured by Brookfield Engineering Laboratory, Inc. , Stoughton, Massachusetts, using spindle 1 at 60 rpm and the Tiki dilution shear, for example, polymers and/or compositions determined using a Carrimed Controlled Stress Rheometer Model CSL 100, manufactured Carrimed Ltd., Interpret House, Curtis Road Estate, Dorking, Surry RH 4 IDP, England. In the rheometer used the geometry of the dual concentric cylinders to make stable measurements of shear at different shear rates. These measurements are carried out at about 26oC. Thinning shear, pseudo-plastic behavior of the system xanthan gum can be mathematically modeled by the equation N=KRn-1where N denotes the apparent viscosity, K denotes a constant consistency, R denotes the shear rate and n denotes the index of the shift. For best results spray (distribution) values of K and n should give a viscosity of less than 15 centipoise at shear rates when spraying (~10000 inverse seconds, as reported in the technical literature).

The behavior of dilution when the shift is described in U.S. patent 4783283 issued Stoddart November 8, 1988, especially in the beginning at column 2, line 46 and forth.

Detergent compositions or solutions, especially those that must be used with the device containing overabsorbed material, preferably require sufficient detergent to make the solution fit to provide treatment without supersaturation overabsorbed material solution, but the solutions usually can't have more than about 0.5% by weight solution of detergent surfactants without compromising its performance. Therefore, the concentration of detergent surfactant in the cleaning solution should be from about 0.01% to about 0.5%, more preferably from about 0.05% to about 0.4% and even more preferably from about 0.05% to about 0.3% by weight solution/composition. To improve preferred cleaning solution may also contain one or more solvents at a concentration of nutrient from about 0.5% to about 2.0% solution.

As discussed above, the pH should be more than about 9.3, preferably more than about 10, more preferably more than about 10.3 to facilitate cleaning when using conventional systems, such as sponge, cloth, MOP, such as mops sponges, tape mops, mops from ropes, floor cloths, etc. and to avoid the difficulties of absorption when using the pillow containing overabsorbed materials, and alkalinity should be preferably provided, at least partially, volatile materials, to avoid problems, education-related bands/films.

Detergent surfactant is preferably linear, for example branching and aromatic groups should not be present, and the detergent surfactant is preferably relatively water-soluble, for example, having a hydrophobic chain containing from about 8 to about 14, preferably from about 8 to about 12 carbon atoms, and, for the nonionic detergent surfactants having the products HLB from about 9 to about 14, preferably from about 10 to about 13, more preferably from about 10 to about 12.

Detergent composition (cleaning solution) is a solution of the water-based, containing one or more detergent surfactants, alkaline materials to provide the desired alkaline pH and optional solvents, builders, chelating agents, prepodavatel, enzymes, etc. Suitable surfactants include anionic, nonionic, zwitterionic and amphoteric surfactants, as discussed above, preferably anionic and nonionic detergent surfactants having a hydrophobic chain containing from about 8 to about 14, preferably from about 8 to about 12 carbon atoms. Examples of anionic surfactants include, but are not limited to, linear alkyl sulphates, alkyl sulphonates and the like. Examples of nonionic surfactants include alkylalkoxy emery amphoteric surfactants include alcelaphinae and alkylenediamines. All of these materials are commercially available and described in McCutcheon''s volume 1: Emulsifiers and Detergents, North American Ed., McCutheon Division, MC Publishing Co., 1997.

Solvent

Suitable solvents include derivatives of short-chain (for example, C1-C6) oxicological and oxypropylene, such as a simple n-hexyl ester of mono - and diethylene glycol, a simple n-butyl ether of mono-, di - and tripropyleneglycol and the like. Other volatile solvents, such as ethanol, isopropanol and the like, are also preferred in this invention.

Prepodavatel

Suitable prepodavatel include silicone polymers and linear or branched C10-C18fatty acids, waxes or alcohols. Dow Corning AF (contains: glycol stearate (4 wt.%, CAS # 9004993), methylated silica (2 wt.%, CAS # 67762907), octamethylcyclotetrasiloxane (2 wt.%, CAS # 556672) is preferred.

Prepodavatel in an effective concentration, generally from about 0.0005 to about 0.02, preferably from about 0.001 to about 0.01, more preferably from about 0.002 to about 0.003 per cent by weight solution/composition, provides technical improvements in the formation of spots and films, especially, prasouda foam upon transverse movement of the MOP. When there is too much foam, it can dry out in bands. In addition, consumer research shows that the foam is visible on the floor during cleaning MOP, is perceived by some consumers as leading to the formation of films/strips.

Reduction foam on the floor during cleaning MOP can provide different degrees of technical and perceived beneficial effects, leaving tapes/strips. The degree of benefit depends on the number of generated foam and to what extent the amount of foam is controlled, especially when wiping MOP.

Can be used known prepodavatel, but it is desirable to use a silicone prepodavatel because they are effective at very low concentrations and therefore can minimize the necessary water-insoluble material, having at the same time, at least an effective amount of the present prepodavatela.

Modifying additives

Suitable modifying agents include soluble additives, especially alkali metal, e.g. sodium and/or potassium and/or amine and/or substituted amine, salts of ordinary modifitsiruemoi oristic sources, such as nitryltriacetic acid, S,S-ethylenediaminetetra acid and the like.

The total concentration of such ingredients is low, preferably less than about 0.1%, more preferably less than about 0.05%, in order to avoid problems with the formation of films/strips. Preferably, the composition should be essentially free of materials that cause problems education films/strips. Accordingly, for the most part, buffer action, it is desirable to use an alkaline materials which do not cause the formation of films and/or strips. Suitable alkaline buffers include carbonate, bicarbonate, citrate, etc. Preferred alkaline buffers are alkanolamine having the formula CR2(NH2)CR2HE, where each R is chosen from the group consisting of hydrogen and alkyl groups containing from one to four carbon atoms, and the sum of carbon atoms in the connection device according to the invention contains from about 0.05% to about 0.3% detergent surfactant, preferably containing detergent surfactant based on linear alcohol ethoxylate (e.g., Neodol 1-5from Shell Chemical Co.) and alkylsulfonate (e.g., BiotergePAS-8s, linear C8the sulfonate from Stepan Co.), from about 0.5 to about 2.0% n-butyl ether of propylene glycol (Dow Co.), from about 0.5% to about 3.0 percent ethanol (Quantum chemicals), from about 0.05% to about 0.25% volatile alkaline material, for example 2-amino-2-methyl-1-propanol, optional auxiliary additives such as colorants and/or fragrances, and from about 99.9% to about 90% deionized or demineralized water.

SYSTEM ACCESSORIES PLUS CLEANSING PILLOW

System accessories plus cleansing cushion in the preferred embodiment, based on the provision of facilities. Therefore, it is preferable to use a device that contains cleansing pillow, preferably removable and/or fixed (removed), which contains overabsorbed material and which preferably also provides a significant cleansing useful effect. Preferred useful cleansing characteristics are relevant to the preferred structural characteristics, described below, in combination with the ability of the here, requires the use of the cleansing composition, as described below, to ensure optimum performance.

Cleansing pillows preferably will have the absorptive capacity, when measured at the bounding pressure of 0.62 kPa (0,09 psi) after 20 minutes (1200 seconds) (hereinafter referred to as "absorptive capacity (capacity) t1200)) at least about 10 g deionized water per g of the cleaning pad. The absorptive capacity of the cushion is measured after 20 minutes (1200 seconds) after he was subjected to deionized water, as this is the usual time for the consumer to clean a hard surface, such as gender. Limiting pressure is normal pressure, attached to the cushion during the cleaning process. As such, cleansing pillow should be able to absorb significant amounts of the cleaning solution during this period of 1200 seconds of 0.62 kPa (0,09 psi). Cleansing pillow would be preferable to have the absorptive capacity of t1200at least about 15 g/g, more preferably at least about 20 g/g, even more preferably at least about 25 g/g and most preferably at least about 30 g/g O, more preferably, the absorptive capacity of t900at least about 20 g/g

The cleansing pads are also preferably, but not necessarily, have a total capacity of liquid (deionized water) of at least about 100 g, more preferably at least about 200 g, more preferably at least about 300 g and most preferably at least about 400, Although the pillows with the overall performance of the liquid is less than 100 g, are within the scope of the invention, they are not as well suited for cleaning large areas, such as in a normal household, as pillows with a higher ability.

A. a Layer of absorbent

The layer of absorbent used for holding any liquid and dirt absorbed cleansing your pillow during use. Although the preferred scraping layer, described later, has some impact on the ability of the cushion to absorb fluid, the absorbent layer plays a major role in the it group layers which are adapted to provide cleansing pillow with numerous flat surfaces.

From a perspective of absorptive capacity for liquids, the absorbent layer will be able to remove the fluid and dirt from any "scraping layer so that the scraping layer was able to continuously remove dirt from the surface. The layer of absorbent material must also be capable of retaining the absorbed material during normal when using pressure to avoid "squeezing" of the absorbed dirt, cleaning solution, etc.

The absorbent layer may include any material that can absorb and retain fluid during use. In order to achieve the desired overall performance of the liquid, it is preferable to include in the layer of absorbent material having a relatively high capacity (expressed in grams of liquid per gram of absorbent material). In the description the term "overabsorbed material" means any absorbent material having the ability to water, at least about 15 g/g, when measured at the bounding pressure of 2.06 kPa (0,3 psi). Cleansing solutions (composition) disclosed above are water, so suppose the spines water-based.

Typical overabsorbed materials include water-insoluble, swellable in water overabsorbed gelling polymers (called "overabsorbed gelling polymers"), which are well known in the literature. These materials exhibit very high absorption capacity for water. Overabsorbed gelling polymers applicable in this invention can have a size, shape and/or morphology, varying within wide limits. These polymers can be in the form of particles that do not have great relations of the largest dimension to the smallest dimension (e.g., granules, flakes, obtained by dispersion of particles, meducation units, meducation stapled units, and the like), or they can be in the form of fibers, sheets, films, foams, laminates and the like. Application overabsorbed gelling polymers in fibrous form provides benefits in providing improved retention overabsorbed material compared to the particles during the cleaning process. Although their ability, usually lower for mixtures of water-based, these materials still exhibit significant absorption capacity for such mixtures. The Pat is Harper and others), issued June 13, 1972, U.S. patent 3770731 (Harmon), issued June 20, 1972, re-issued U.S. patent 32649 (Brandt and others ), re-issued April 19, 1989, U.S. patent 4834735 (Alemany and others), issued may 30, 1989.

Overabsorbed gelling polymers applicable in this invention include a variety of water-insoluble, but swellable in water, the polymers capable of absorbing large quantities of liquids. Such polymeric materials are usually also referred to as "hydrocolloids" and can include polysaccharides such as carboximetilkrahmal, carboxymethylcellulose and hydroxypropylcellulose; nonionic types such as polyvinyl alcohol and polyvinyl ethers; cationic types such as polyvinylpyridine, polivinilpirrolidon and N,N-dimethylaminoethyl or N,N-diethylaminopropylamine and methacrylates, and their corresponding Quaternary salts. Usually overabsorbed gel-forming polymers that are useful, have a lot of anionic functional groups such as sulfonic acid group and, more generally, carboxypropyl. Examples of polymers suitable for use include those that are derived from polymerized, unsaturated, containing acid monomers. So did the od-carbon olefinic double bond. More specifically, these monomers can be selected from alafinova unsaturated carboxylic acids and anhydrides of acids, alafinova unsaturated sulfonic acids and mixtures thereof.

Some non-acidic monomers may also be included, usually in small quantities, upon receipt overabsorbed gel-forming polymers useful in the invention. Such non-acidic monomers may include, for example, water-soluble or water-dispersible esters containing acid monomers, and monomers which do not contain any carboxylic group or sulfonic acids. Optional non-acidic monomers can, thus, include monomers containing the following types of functional groups: the group of esters of carboxylic acid or sulfonic acid, hydroxyl groups, amide groups, amino groups, nitrile groups, Quaternary ammonium salts, aryl groups (e.g. phenyl groups, such as groups derived from monomer styrene). These non-acidic monomers are well known materials and are described in more detail, for example, in U.S. patent 4076663 (Masuda and others), issued February 28, 1978, and in U.S. patent 4062817 (Westerman), issued December 13, 1977.

These polymers can be used either as such or in the form of a mixture of two or more different polymers. Examples of such polymeric materials are disclosed in U.S. patent 3661875, U.S. patent 4076663, U.S. patent 4093776, U.S. patent 4666983 and U.S. patent 4734478.

Most preferred polymer materials for use in obtaining overabsorbed gelling polymers are poorly sewn mesh polymers of partially neutralized polyacrylic acids and their derivatives with starch. Most preferably, forming the hydrogel absorbent polymers contain from about 50% to about 95%, preferably about 75%, neutralite stitching makes the polymer is essentially insoluble and partially determines the absorptive capacity and characteristics of the extracted content of the polymer overabsorbed gelling polymers. How net crosslinking of these polymers and typical mesh cross-linking agents are described in more detail in U.S. patent 4076663.

Although the preferred overabsorbed gel-forming polymers of the same type (i.e. homogeneous), mixtures of polymers can also be used in the devices used in the preferred embodiment. For example, the present invention can be used mixtures of graft copolymers of starch and acrylic acid and weakly crosslinked mesh polymers of partially neutralized polyacrylic acid.

Although any of overabsorbed gel-forming polymers described in the prior art, can be useful in this invention, recently found that, when a significant amount (for example, more than about 50% by weight of the absorbent structure) overabsorbed gelling polymers should be included in the absorbent structure and, in particular, when one or more portions of the layer of absorbent material will contain more than about 50% by weight of the parcel, the problem of blocking of the swollen gel particles can impede fluid flow and thereby adversely affect the ability of gelling polymers can absorb up to their 49335 (Kellenberger and others), issued September 22, 1992, describe overabsorbed gelling polymers in relation to their absorption capacity under load (AUL), where gelling polymers absorb liquid (0,9% saline solution) under limiting the pressure of 2.06 kPa (0,3 psi). (The contents of each of these patents are included in the description). Methods for determining AUL described in these patents. Those described in these polymers can be particularly useful in embodiments of the present invention, which contain areas of relatively high concentration overabsorbed gelling polymers. In particular, when high concentrations overabsorbed gel-forming polymer include cleansing pillow, these polymers should preferably have AUL, measured according to the methods described in U.S. patent 5147343 at least about 24 ml/g, more preferably at least about 27 ml/g after 1 hour, or AUL, measured according to the methods described in U.S. patent. 5149335, at least about 15 ml/g, more preferably at least about 18 ml/g after 15 minutes. Located on the simultaneous consideration of the application of the U.S. with the assigned sequence numbers 08/219547 (Goldman and others), filed on March 29, 1994, and 08/416396 (Goldman and others), filed on April 6, 1995, taki overcome this phenomenon. These applications specifically describe overabsorbed gel-forming polymers, which allow to avoid blocking gel even at a higher limiting pressures, specifically of 4.8 kPa (0,7 psi). In embodiments of the present invention where the absorbent layer will contain areas containing a high concentration (for example, more than about 50% by weight of the parcel) overabsorbed gelling polymer, it may be preferable to overabsorbed gelling polymer was the same as described in the aforementioned applications of Goldman and other

Other useful overabsorbed materials include hydrophilic polymeric foam, such as those described in located on the simultaneous consideration of the patent application U.S. assigned serial 08/563866 (DesMarais and others ), filed on November 29, 1995, and U.S. patent 5387207 (Dyer and others), issued February 1, 1995. These references describe polymeric hydrophilic absorbent foam, which is produced by polymerization of emulsion water-in-oil with a high content of the internal phase (usually called HIPE). These foams are easily adapted for varying physical properties (pore size, capillary absorption, density and so on) that affect the ability of the such foams or fibrous structures to ensure total capacity.

When overabsorbed material included in the absorbent layer, the absorbent layer will preferably contain at least about 15% by weight of the layer of absorbent material, more preferably at least about 20%, even more preferably at least about 25% overabsorbed material.

The absorbent layer may also consist of a fibrous material, or contain it. Fibers useful in this invention include those that occur in nature (modified or unmodified), as well as synthetically derived fiber. Examples of suitable unmodified/modified naturally occurring fibers include cotton, grass Esparto, bagasse, hemp, flax, silk, wool, wood pulp, chemically modified wood pulp, jute, ethylcellulose and cellulose acetate. Suitable synthetic fibers can be obtained from polyvinyl chloride, polyvinyl, polytetrafluoroethylene, polyvinylidenechloride, polyacrylic compounds, such as ORLON, polyvinyl acetate, RAYON, polyethyleneamine, insoluble or soluble polyvinyl alcohol, polyolefins such as polyethylene (e.g., PULPEX, polyurethanes, polystyrenes, and the like. The absorbent layer may contain only naturally occurring fibers, synthetic fibers, or any compatible combination of naturally occurring and synthetic fibers.

Useful in the invention, the fibers may be hydrophilic, hydrophobic or can be a combination of both hydrophilic and hydrophobic fibers. As indicated above, the specific choice of the hydrophilic or hydrophobic fibers will depend on other materials included in the layer of adsorbent (and, to some extent, scraping the layer). That is the nature of the fibers is preferably such that the cleansing pillow detects the preferred fluid retention and overall absorptive capacity for liquids. Suitable for use in this invention are hydrophilic fibers include cellulosic fibers, modified cellulosic fibers, rayon, polyester fiber, such as hydrophilic nylon (HYDROFIL). Suitable hydrophilic fibers can also be obtained by hydrophilization hydrophobic fibers, such as processed surface-active substance or treated silicon dioxide thermoplastic fiber is s, polyamides, polystyrenes, polyurethanes and the like.

Suitable fibers from wood pulp can be obtained by a well-known chemical processes such as sulfate and sulfite pulping processes pulp. Especially, it is preferable to obtain these fibers from wood pulp of soft wood southern rock because of its good characteristics of absorptive capacity. These fibers from wood pulp can also be obtained by mechanical processes such as the processes of pulping, mechanical grinding, thermomechanical, chemical-mechanical and chemi-thermomechanical. Can be recycle used or recycled fiber from wood pulp and fiber from bleached and unbleached wood pulp.

Another type of hydrophilic fibers for use in this invention are chemically hardened (thickened) pulp fibers. In the description, the term "chemically hardened cellulose fibers" refers to fibers which have been hardened by chemical means to increase stiffness of the fibers in both dry and aqueous conditions. Such means may include the addition of chemical uprochenie fibers by modifying the chemical structure, for example, by cross-linking of polymer chains.

When fibers are used as the absorbent layer (or component), optional fiber can be combined with a thermoplastic material. Melting at least part of this thermoplastic material migrates to the intersections of the fibers, usually due to interfiber capillary gradients. These intersections become places due to a thermoplastic material. When cooled, thermoplastic material at those intersections otverzhdajutsja education places ties that hold the matrix or webs of fibers together in each of the respective layers. This can be useful to give additional overall integrity cleansing pillow.

Along with their various effects, binding at the intersections of the fibers increases the overall modulus of elasticity in compression and the strength of the resulting heat-related item. In the case of chemically reinforced cellulose fibers, melting and migration of thermoplastic material also has the effect of raising the average pore size of the obtained fabric, while at the same time, the density and basis weight of the fabric, as Pern canvas with the initial impact of the liquid, due to the enhanced permeability for liquids and subsequent impact, thanks to the combined capacity of reinforced fibers to maintain its rigidity when the wetting and the ability of thermoplastic material to be connected at the intersections of the fibers during wetting and compression in a wet state. In the structure thermally connected cloth reinforced fibers retain their original total volume, but the volume areas previously occupied by thermoplastic material, to be open, to thereby increase the average size of interfiber capillary pores.

Thermoplastic materials useful in this invention may be any of a variety of forms, including particles, fibers, or combinations of particles and fibers. Thermoplastic fibers are particularly preferred form due to their ability to form numerous places interfiber bonds. Suitable thermoplastic materials can be obtained from any thermoplastic polymer that can be melt at temperatures that will not significantly harm the fibers that contains the primary fabric or matrix of each layer. Preferably, temperate 75oWith and about 175oC. In any case, the melting point of this thermoplastic material should be no lower than the temperature at which it remains the likelihood of heat-related structures of the absorbent when used in cleansing pillows. The melting temperature of thermoplastic material is usually not lower than about 50oC.

Thermoplastic materials and, in particular, thermoplastic fibers can be made from a variety of thermoplastic polymers, including polyolefins such as polyethylene (e.g., PULPEXand polypropylene, polyesters, complex sobolifera, polyvinyl acetate, polietilenimin, polyvinyl chloride, grades, polyacrylic compounds, polyamides, copolyamids, polystyrenes, polyurethanes and copolymers of any of the foregoing such as vinyl chloride/vinyl acetate and the like. Depending on the desired characteristics for the resulting thermally linked absorbent element suitable thermoplastic materials include hydrophobic fibers that have been made hydrophilic, such as processed surface-active substance or treated silicon dioxide thermoplastics the developments polyamides, polystyrenes, polyurethanes and the like. The surface of the hydrophobic thermoplastic fibers can be made hydrophilic by treating the surface-active agent such as nonionic and/or anionic surfactant, for example by spraying the surface-active substance on the fiber by immersing the fiber in a surface-active substance or by including a surfactant as part of the polymer melt in the production of thermoplastic fibers. Melting and re-solidification surfactant will tend to remain on the surfaces of thermoplastic fibers. Suitable surfactants include nonionic surfactants such as Brij76 manufactured by ICI Americas, Inc. of Wilmington, Delware, and various surfactants sold under the trademark PegosperseGlyco Chemical, Inc. of Greenwich, Connecticut. In addition to the nonionic surfactants can also be used anionic surfactants. These surfactants can be applied to thermoplastic fibers in amounts, for example, from about 0.2 to about 1 g/one polymer (single-fiber) or can be made of more than one polymer (for example, bicomponent fibers). In the description of the "two-component fiber" refers to a thermoplastic fibers, which contain heart-shaped fiber obtained from the same polymer, which is enclosed within a thermoplastic sheath, derived from another polymer. The polymer comprising the shell, often melts at a different, typically lower temperature than the polymer comprising the core. As a result, such a two-component fibers provide thermal binding due to melting of the polymer shell, while at the same time the required strength characteristics of the polymer core.

Suitable for two-component fibers may include fibers are sheath/core having the following polymer combinations: polyethylene/polypropylene, polietilenimin/polypropylene, polyethylene/polyester, polypropylene/polyester, copolyester/polyester, and the like. Particularly suitable for use with two-component thermoplastic fibers are those which have a core of polypropylene or polyester and the sheath of the more low-melting of sobolifera, polyethyleneamine or polyethylene (e.g., such as from Danaklon a/s, Chisso Corp., and CELBONDfrom Hercu the concentric" and "eccentric" attitude towards does the shell thickness, which is the same or different cross-sectional area of a two-component fiber. Eccentric bicomponent fibers may be desirable to provide greater strength in compression for smaller thicknesses of the fiber.

Methods of obtaining thermally related fibrous materials are described in concurrently pending application U.S. serial 08/479096 (Richards and others), filed July 3, 1995 (see especially pages 16-20), and in U.S. patent 5549589 (Dogpaw and others), issued August 27, 1996 (see especially columns 9-10).

The absorbent layer may also contain HIPE-derived hydrophilic polymer foam, which has a high absorption capacity of those materials described above as "overabsorbed materials". Such foams and methods for their preparation are described in U.S. patent 5550167 (DesMarais), issued August 27, 1996, and located on the simultaneous consideration of the patent application U.S. appropriated 08/370695 (Stone and others, filed January 10, 1995.

A layer of an absorbent cleaning pad can consist of a homogeneous material, such as a mixture of cellulose fibers (optional thermally connected) and razbegaevo overabsorbed is a, such as a layer of thermally linked material obtained by coating the air, and a discrete layer overabsorbed material. For example, a thermally-linked layer of cellulosic fibers may be placed lower than (i.e., below) overabsorbed material (i.e., between overabsorption material and scraping the layer). In order to achieve a high level of absorption and retention of fluids under pressure, while at the same time initial delay absorption of the liquid, it may be preferable to use such discrete layers during formation of the layer of absorbent material. In this respect overabsorbed material can be placed away from the scraping layer by incorporating less absorbent layer as the lower side of the absorbent layer. For example, a layer of cellulosic fibers can be placed below (i.e., below) than overabsorbed material (i.e., between overabsorption material and scraping layer).

In a preferred embodiment, the absorbent layer will contain thermally connected, the obtained coating air webs of cellulose fibres (Flint River from Weyrhaeuser, Wa, and AL With Thermal-thermoplastic material from Danaklon a/s, Varde, Denmark) and nabuhay the top and the concrete layer is placed near the surface of the layer of absorbent material, which is remote from the scraping layer. Preferably, a thin layer of, for example, of cellulose fibers (optional thermally connected) is placed over overabsorbed gelling polymer to improve retention.

C. an Optional, but preferred scraping layer

Scraping the layer is part of the cleansing pillows which come in contact with contaminated surface during cleaning. As such, the materials useful as scraping layer are preferably strong enough so that the layer will retain its integrity during the cleaning process. In addition, when cleaning the pillow used in combination with solution, scraping the layer preferably is able to absorb liquids and dirt and to transmit these fluids and dirt absorbent layer. It will ensure that scraping the layer will be able to constantly remove additional material from the surface being cleaned. If they use the device with a cleaning solution (i.e., wet) or without cleaning solution (i.e., dry), scraping the layer will, in addition to removing particles, to facilitate other functions, such as polishing, wipe dust and polishing the cleaned Powergen which can be cut, to facilitate ottiene contaminated surface and absorption of particles. This scraping layer as it passes over the contaminated surface, interacts with the dirt and cleaning solution, when it is used), loosening and amblyraja dense pollution and allowing them to move freely in the layer of absorbent pillows. Scraping the layer preferably contains openings (e.g., cracks), which provide an easy way for larger dirt particles, so that it moves freely and was located inside the layer of absorbent pillows. For use as a scraping preferred layer structure of low density, to facilitate the transfer of particles to the layer of absorbent pillows.

In order to provide the required integrity, materials, especially suitable for scraping layer include synthetic materials such as polyolefins (e.g. polyethylene and polypropylene), polyesters, polyamides, synthetic pulp (for example, RAYON) and their mixtures. Such synthetic materials may be manufactured using a known method, such as the search on the carding machine, binding, twisting, blowing from the melt, coating the transport stream of the present invention may not necessarily have the anchoring layer, which allows you to attach the pillow to the handle attachments or supporting (supporting) the crown in preferred devices. Anchoring layer will be required in those embodiments where the absorbent layer is unsuitable for attaching the cushion to support the head arm. Anchoring layer can also function as a means to prevent fluid flow through the upper surface (i.e. the surface in contact with the arm) cleansing pillows, and may additionally provide enhanced integrity of the pillow. As scraping and absorbent layers anchoring layer may consist of single layer and multilayer structures until it meets the above requirements.

In a preferred embodiment of the present invention anchoring layer will contain the surface, which is able to mechanically attach to the support cylinder and arm by using a known method of fastening the hook and loop. In this embodiment, anchoring layer will contain at least one surface, which may be mechanically attached to the hooks that are permanently attached to the bottom surface of the reference head arm.

Crispelltoday layered structure, containing, for example, a film formed by the blowing of the melt, and the fibrous nonwoven structure. In a preferred embodiment, anchoring layer is a three layer material having a layer formed by the blowing of the melt polypropylene film, placed between two layers of linked twist (twisted) fibers of polypropylene.

D. Optional, but preferred the numerous flat surface

Although the ability of cleansing pillows to absorb and retain liquids, as defined, is an important characteristics for cleaning a solid surface (see, for example, located on the simultaneous consideration of the patent application U.S. serial 08/756507 (Holt and others), located on the simultaneous consideration of the patent application U.S. serial 08/756864 (Sherry and others) and found on the simultaneous consideration of the patent application U.S. serial 08/756999 (Holt and others), all filed November 26, 1996), desirable characteristics can be achieved by determining properly the overall structure of the cleansing pillows. In particular, pillows, having essentially a flat surface in contact with the floor, (i.e., essentially one flat surface for contact with zagrjaznen the tends to accumulate at the leading edge, which is also an important point where the cleaning solution is transferred to a layer of absorbent material.

Preferred pillows have many flat surfaces during the cleaning and provide improved operational characteristics. In the figure 2 cleansing pillow 100 has an upper surface 103, which allows you to attach the pillow with the possibility of release to the handle. Cleansing pillow 100 has a lower surface 110, which is in contact with the floor or other hard surface during cleaning. This bottom surface 110 actually consists of 3 essentially flat surfaces 112, 114 and 116. Plane corresponding to the surfaces 112 and 116 intersect with the plane corresponding to the surface 114. Therefore, when the device to which you attach the cushion 100, move from a state of rest in the direction of Yfthe friction causes the cushion 100 to oscillate so that the bottom surface 112 is in contact with the surface being cleaned. When the movement in the direction of Yfweakened, then the bottom surface 114 will be in contact with the surface being cleaned. When the device and the cushion is moved from its rest position in the direction of Ybthe friction causes its movement again, part of the cushion in contact with the contaminated surface, constantly replaced.

It is believed that improved cleaning preferred pillow is partly a consequence of the "lifting" action, which is the result of the reciprocating movement during cleaning. In particular, when the cleaning motion in one direction, stop and effort applied to the device, allow the cushion 100 to oscillate so that contact with the cleaned surface is a flat surface moves from the surface 112 (or 116) to the surface 114, the dirt is moved in the upward direction.

Cleansing the pillow of this invention must be capable of retaining the absorbed liquid even during the pressure exerted during the cleaning process. It is considered as the ability of cleansing pillows to exclude "wringing out" of the absorbed liquid, or, conversely, the ability to retain the absorbed fluid under pressure. Method of measurement "push-UPS" described in "test Methods". In short, the test measures the ability of rich cleansing pillows to retain fluid when it is subjected to pressure of 1.66 kPa (0.25 psig). Preferably, the cleansing pillows completion 25%, even more preferably not more than about 15% and most preferably no more than about 10%.

CLEANING EQUIPMENT

Detergent compositions described above can be preferably used with a device for cleaning the surface, which contains the handle and removable (deleted) purifying the pillow, containing an effective amount overabsorbed material and has many essentially flat surfaces, where each of the essentially flat surfaces in contact with the surface being cleaned. More preferably, this pillow is removable cleaning pad having a length and width, and pillow contains scraping layer and the absorbent layer containing the first layer and the second layer, where the first layer is placed between the scraping layer and the second layer (i.e. the first layer is below the second layer and has a smaller width than the second layer.

An important aspect of cleansing characteristics, provide the preferred pillow, refers to the ability to provide numerous flat surfaces that come into contact with contaminated surface during cleaning operations. As for cleaning equipment such as mops, these flat over the but and forth in the direction essentially parallel to the Y-dimension or width of the pillow) each of the flat surfaces in contact with the surface being cleaned in the "variations" cleansing pillows. This aspect of the invention and the resulting advantages are discussed in detail with reference to the figures.

The specialist will understand that various materials can be used for carrying out the invention. Thus, although the preferred materials described below for the various components of fixtures and cleansing pillows, it should be understood that the invention is not limited to such disclosures.

Arm

Handle the specified cleaning equipment can be made of any material which would facilitate grasping cleaning equipment. The handle of the cleaning device is preferably to contain any longer durable material, which will provide practical cleaning. Arm length will be determined by the end use devices.

The handle will preferably contain at one end of the abutment (supporting) head, to which can be attached with the possibility of liberation cleansing pillow. To facilitate the s connecting nodes. Can be used with any suitable means for fastening cleansing pillows to support the head while cleaning the pillow remains attached during the cleaning process. Examples of suitable anchoring means include clips, hooks and loops (e.g., VELCRO), and the like. In a preferred embodiment, the supporting cylinder will contain hooks on its lower surface, which will be mechanically attached to the top layer (preferably a separate anchoring layer) absorbent cleansing pillows.

The preferred arm containing the means of the liquid distribution shown in figure 1a and described in detail are on the simultaneous consideration of the patent application U.S. serial 08/756774, filed November 15, 1996 V. S. Ping and others (Case 6383). Another preferred arm, which does not include funds liquid distribution, shown in Fig.1A and 1b and described in detail are on the simultaneous consideration of the patent application U.S. serial 08/716755, filed September 23, 1996 A. J. Irwin and others (P&G Case 6262).

Cleansing pillow

Cleansing pillows, described above, can be used without attachment to the handle or as part of the above ochimusha. so that they can be used either in combination with a handle, or as a separate product. Thus, it may be preferable to make pillows with optional anchoring layer, as described previously. Except for the anchoring layer, pillows themselves are the same as described above.

In the description, the term "direct liquid message" means that the liquid can easily be transferred between two components or layers cleansing pillows (i.e., scraping the layer and the layer of absorbent material) without significant accumulation, transfer or restriction layer introduced between them. For example, fabrics, non-woven cloth, structural binders and the like may be present between two separate components, while at the same time, the "direct fluid communication" as they essentially do not interfere or not to keep the liquid as it passes from one component or layer to another.

In the description, the term "Z-dimension" refers to the dimension perpendicular to the length and width of the cleaning pads of the present invention or its components. Z-dimension usually corresponds to the thickness of cleansing pillows or component pillows.

In the description termie generally correspond to the length and width, respectively cleansing pillows or component pillows. Typically, when cleansing the pillow is used in connection with the handle, the device will move in a direction parallel to the Y-size pillows (see discussion below).

In the description, the term "layer" refers to an element or component cleansing pillows, essential dimension which X-Y, i.e., along its length and width. It should be understood that the term "layer" is not necessarily limited to single layers or sheets of material. Thus, the layer may contain laminates or combinations of several sheets or cloths required types of materials. Accordingly, the term "layer" includes the terms "layers" and "layered".

In the description, the term "hydrophilic" is used with respect to the surfaces which are wetted by water liquids placed on them. The hydrophilicity and wettability is usually defined in terms of contact angle and surface tension of liquids and entrained solid surfaces. This is discussed in detail in a publication of the American chemical society, entitled "Contact Angle, Wettability and Adhesion", published by Robert F. Gould (Copyright 1964). The surface is called the wetted by a fluid (i.e., hydrophilic), or when the contact angle between the liquid and the surface status and, usually both conditions coexist. Conversely, a surface is considered hydrophobic if the contact angle is more than 90oand the liquid is distributed spontaneously on the surface.

In the description the term "rough canvas" means any durable material that provides texture on the contact surface side of the scraping layer cleansing pillows and also has sufficient openness to allow the necessary movement of a liquid to the layer of absorbent cleaning pad. Suitable materials include materials that have continuous open structure, such as the sieve of synthetic and wire mesh. The open area of these materials can be easily adjusted by changing the number of interconnected strands that contains the grid, by regulating the thickness of these interrelated strands, etc. Other suitable materials include texture which provide intermittent pattern printed on the substrate. In this aspect, durable material (e.g., synthetic) may be caused to be printed on the substrate in a continuous or discontinuous pattern, such as a single point or line, to provide the necessary texture is St then will act as a rough canvas. These drawings can be repeated or they can be messy. It should be clear that one or more of the approaches described to provide the desired texture can be combined to education optional material coarse canvas. The height direction Z and an open area of rough linen and/or scraping the substrate layer to help regulate and/or slow down the flow of liquid into the absorbent core material. The height Z of the rough canvas and/or scraping of the substrate helps to provide a means to regulate the amount of liquid in contact with a cleaning surface, adjusting at the same time the speed of the absorption liquid, liquid a message in the absorbent core material.

For the purposes of this invention "top" layer of cleansing pillows is a layer that is relatively remote from the surface that must be cleaned (i.e., relatively close to the handle of the device during use). The term "lower" layer, on the contrary, refers to the layer of cleansing pillows, which is relatively close to the surface that must be cleaned (i.e. relatively remote from the arm of the unit during ispolzovaniya to scraping layer. The terms "upper" and "lower" are used with respect to the layers that are laminated (for example, when scraping the layer is double-layered material). The terms "above" and "below" are used to describe relative locations of two or more materials in the thickness of the cleaning pad. For illustration, the material a is "above" the material, if the material is located closer to the scraping layer than material A. Similarly, the material is "below" the material in this illustration.

All percentages, ratios, and proportions used in the description, taken in the mass, except otherwise indicated, all numerical limits are normal approximations within the normal range accuracy.

OTHER OPTIONS CLEANSING PILLOWS

To enhance the ability of the cushion to remove dense dirt and increase the amount of cleaning fluid in contact with a cleaning surface may be desirable to include material coarse canvas in cleansing the pillow. Rough canvas will contain a solid dense material, which will provide texture scraping a layer of cushion, especially when the pressure to make the pillow during use. Preferably, the coarse canvas baby canvas can be included as part of scraping a layer or layers of absorbent material, or it may be included as a separate layer, preferably located between the scraping layer and the absorbent layer. In one preferred embodiment, where the material is coarse canvas has the same X-Y-size, as all cleansing pillow, it is preferable that the material of coarse canvas was included so that it is not directly in contact, to a considerable extent, with the surface being cleaned. This will support the ability of the cushion to move easily on a hard surface and will help prevent uneven removal of the used cleaning solution. So, if rough canvas is part of the scraping layer, it will be the top layer of this component. Of course, rough canvas at the same time must be positioned low enough in the pillow to ensure that its scraping function. So, if rough canvas is included as a part of the layer of absorbent material, it will be the bottom layer. In a separate embodiment, it may be desirable to place a rough canvas so that he was in direct contact with the surface being cleaned.

In addition to the importance of correct positioning of coarse canvas is what rough canvas does not significantly impede the flow of liquid through the pillow. Therefore, rough canvas is relates processed, to ensure sturdy canvas with an open texture. Such materials include polyolefins (e.g. polyethylene, polypropylene), polyesters, polyamides and the like. The specialist must understand that these different materials exhibit different degrees of rigidity. Therefore, the rigidity of the material of coarse canvas can be adjusted depending on the final application pillows/accessories. When the coarse canvas include in the form of a discrete layer, there are many commercial sources of such materials (for example, project number V01230 from Conwed Plastics, Minneapolis, MN). Alternatively, coarse canvas can be enabled by applying an imprint resin or other synthetic material (e.g., latex) on the substrate as disclosed in U.S. patent 4745021 issued by Ping, III, and others may 17, 1988, and U.S. patent 4733774 issued by Ping, III, and others on March 29, 1988.

Different layers that contains cleansing pillow, can be linked together by any means which provide sufficient integrity pillows during the cleaning process. Scraping and anchoring layers can be attached to the layer of absorbent or to each other by any of a variety of binders, including the use of uniform continuously the th or points of the binder. Alternatively, the connecting means may contain links warmth, connection pressure connection ultrasound, dynamic mechanical connection or any other suitable connecting means or combinations of these connecting means, which are known in the art. The connection can be around the perimeter cleansing pillows (for example, hot fill scraping layer and an optional anchoring layer and/or material coarse canvas) and/or over the entire area (i.e., in the X-Y plane) cleansing pads so as to form a pattern on the surface cleansing pillows. The connection layers cleansing pillows by ultrasonic welding with the formation of ties in a square pillow will ensure the integrity, to avoid sliding of the individual layers of the pillow during use.

Figure 3 is a perspective view removable (deleted) cleansing pads 200, containing scraping layer 201 anchoring layer 203 and the absorbent layer 205 located between the scraping layer and the anchoring layer. Cleansing cushion 200 is not depicted as having numerous essentially flat surface. As indicated above, while figure 3 depicts each of the layers 201, 203 and 205 as a single layer of material, edocfile version scraping layer 201 is a two-layer laminated material of combed polypropylene, where the bottom layer is cut. Also, although not shown in the figure 3, the materials that do not inhibit the flow of liquid may be placed between the scraping layer 201 and the absorbent layer 205 and/or between the absorbent layer 205 and the anchoring layer 203. However, it is important to scraping and absorbent layers had substantial liquid message to provide the necessary absorptive capacity cleansing pillows. Although figure 3 depicts the cushion 200 as having all the layers of pillows equal dimensions in the X - and Y-dimensions, it is preferable to scraping the layer 201 and the anchoring layer 203 is greater than the absorbent layer, so that the layers 201 and 203 can be joined together around the periphery of the cushion to ensure integrity. Scraping and anchoring layers can be attached to the layer of absorbent or to each other by any of a variety of connecting means, including the use of a uniform continuous layer of binder, the layer of binder in the form of a drawing or of any number of separate lines, spirals or spots of the binder. Alternatively, the connecting means may contain links warmth, connection pressure connection ultrasound, dynamic mechanical connection, or any others whom the Association may be around the perimeter cleansing pillows and/or over the entire surface scraping layer with the to form a pattern on the surface scraping layer 201.

Figure 4 is a disassembled perspective view of a layer of absorbent 305 variant cleansing pillows of the present invention. Scraping the layer of purifying air bags and optional anchoring layer is not shown in figure 4. The absorbent layer 305 is depicted in this embodiment as consisting of three-layer structure. Specifically, as shown, the absorbent layer 305 comprises a discrete layer of powdered (particulate) overabsorbed gelling material 307, placed between two separate layers 306 and 308 of the fiber material. In this embodiment, because of section 307 high concentration overabsorbed gel-forming material preferably overabsorbed material did not show blocking gel that was discussed above. In a particularly preferred embodiment, the fibrous layers 306 and 308 each will be thermally connected by fibrous substrate of cellulose fibers and lower fibrous layer 308 is in direct fluid communication with scraping layer (not shown). (Layer 307, an alternative may be a mixture of fibrous material and overabsorbed material, where overabsorbed material predoni as of equal width, in a preferred embodiment, the layer 306 is wider than the layer 307, and the layer 307 is wider than the layer 308. When scraping and anchoring layers, this combination will provide a pillow having multiple essentially flat surface of the present invention.

Figure 5 represents a cross section (along the y-z plane) cleansing pillows 400 having scraping layer 401 anchoring layer 403 and the absorbent layer 404 disposed between scraping and anchoring layers. The absorbent layer 404 consists of three separate layers 405, 407 and 409. Layer 409 is wider than the layer 407, which is wider than the layer 405. This narrowing of the materials of the layer of absorbent material provides numerous flat surfaces 411, 413 and 415. (For the purposes of discussion surface 411 call the front edge of the cleansing cushions 400, when the pillow is attached to the device surface 413 call back edge of the cushion 400). In one embodiment, the layers 405 and 407 contain a high concentration of overabsorbed material, while the layer 409 contains a small amount or does not contain overabsorbed material. In such embodiments, one or both layers 405 and 407 may consist of a homogeneous mixture overabsorbed material and fibrous material. Alto essentially continuous layer overabsorbed particles.

It was found that it may be desirable to reduce the concentration overabsorbed particles or exclude them in the extreme front and rear edges. This is done in the cushion 400 by constructing absorbent layer 409 without overabsorbed material.

TEST METHODS

Operational characteristics under pressure

In this test determines the absorption gram/grams deionized water for cleansing pillows, which horizontally limit in the piston/cylinder during the initial limiting the pressure of 0.09 psi (about 0.6 kPa). (Depending on the composition of the sample cleansing pillows to limit the pressure may be slightly reduced when the sample absorbs water and swells during the test). The purpose of the test is to assess the ability of cleansing pillows to absorb fluid within a practical period of time, when the cushion is exposed to conditions of use (horizontal mitilene and pressure).

Sample cleansing pillows is round, having a diameter of 5.4 see (Although the pattern 560 is depicted as a single layer, the sample will actually consist of all of the sample with all layers accommodated by the pillow, from which a sample is cut out). The cylinder 554 is made from a transparent LEXAN rod(or equivalent) and has an internal diameter of 6 cm (size 28,25 cm2) with a wall thickness of approximately 5 mm and a height of approximately 5 cm Piston 556 has the form of a Teflon Cup and machined for a tight fit in the cylinder 554 with small tolerances. Cylindrical cargo 558 stainless steel machined for a tight fit inside the piston 556 and is inserted with the handle on top (not shown) for convenience when it is deleted. The total mass of the piston 556 and cargo 558 equal 145,3 g, which corresponds to a pressure of 0.6 kPa (0,09 psi) square 22.9 cm2.

Components at the pressure of 10 cm are equal, at least 0.01 t/cm2/s, where the flow velocity is normalized by the area of the melted funnel 518. Factors that have a particular impact on the flow velocity, is the permeability of the fused disk in melted funnel 518, the internal diameter of the glass tube 524, 530, 534, 542, 546 and a and valves shut-off valves 528 and 540.

The reservoir 512 is placed on an analytical balance 516, which has an accuracy of at least 0.01 g with a deviation of less than 0.1 /h Scales are preferably connected via an interface with computer software that can track changes in the contrast set intervals of time from the beginning of the test PUP and be installed on avtorizirovannye load change by 0.01-0.05 g, depending on the sensitivity of the balance. Capillary tube 524, a part of the reservoir 512, should not be in contact with either its bottom or cover 514. The volume of fluid (not shown) in the tank 512 should be sufficient so that the air does not penetrate into the capillary tube 524 during measurement. The fluid level in the reservoir 512 first measurement should be approximately 2 mm below the top surface of the molten disc in melted funnel 518. This can be maintained by placing multivar 512. This level should not significantly change when the node 520 of the piston/cylinder is placed inside the funnel 518. The tank should have a significantly larger diameter (for example, ~ 14 cm), so that the removal of portions of ~40 ml led to changes in the height of the liquid is less than 3 mm

Before measurement site is filled with deionized water. Fused disc in melted funnel 518 directed washed so that it is filled with fresh deionized water. If possible, air bubbles are removed from the bottom surface of the fused disk and from the system, which connects the funnel with the tank. The following procedure is carried out by successive steps 3-way shut-off taps:

1. The excess liquid on the upper surface of the molten disc is removed (for example, drain) of the melted funnel 518.

2. The height and weight of a solution in the reservoir 512 is brought to the appropriate level and amount.

3. Melted funnel 518 is placed exactly in height relative to the reservoir 512.

4. Melted funnel 518 then cover with a lid 522 for molten crater.

5. The reservoir 512 and melted funnel 518 counterbalance valves 528 and 540 knots shut-off valves 526 and 538 in the open soybeans is to, that funnel opening to the drainage tube 544.

8. The system allows to be balanced in this position for 5 minutes.

9. The valve 540 is then returned to its closed position.

Stages 7-9 temporarily "dry" surface melted funnel 518 by exposure to small hydrostatic suction ~5 see This absorption makes, if the open end of the tube 544 is at ~5 cm below the level of the molten disc in melted funnel 518, and fill the funnel with deionized water. Usually ~0.04 g of the liquid is drained from the system during this procedure. This procedure prevents premature absorption of deionized water when the node 520 of the piston/cylinder placed inside a sealed funnel 518. The amount of fluid that drains from the melted craters in this procedure (referred to as the mass correction melted funnel or Wffc"), measured by testing PUP (see below) for a period of time of 20 minutes without node 520 of the piston/cylinder. Essentially all the fluid leaked from the melted funnel through this procedure, very quickly re-absorbed by the funnel, when you start the test. It is therefore necessary to subtract the weight correction of the mass of liquid removed is between the cylinder 554. The piston 556 vidvigayt in the cylinder 554 and placed on top of the sample 560 cleansing pillows. Node 520 of the piston/cylinder is placed on top of the melted part of the funnel 518, cargo 558 flushed down the piston 556 and the top of the funnel 518 then close the lid 522 for molten crater. After checking the readings of the scales on the stability begin the test by opening valves 528 and 540 so as to connect the funnel 518 and the reservoir 512. With avtorizirovannym data collection begins immediately when the funnel 518 begins to re-absorb the liquid.

Data recorded at intervals over a total time period of 1200 seconds (20 minutes). The absorptive capacity of the PUP is determined as follows:

t1200absorption capacity (g/g)=[Wr(t=on)-Wr(t=1200)-Wffc]Wds,

where t1200absorptive capacity refers to the capacity yoy pillows after 1200 seconds, Wr(t=o)indicates the weight in grams of reservoir 512 before initiation, Wr(t=1200)indicates the weight in grams of reservoir 512 1200 seconds after initiation, Wffc denotes the mass correction melted funnel and Wds indicates the dry mass of the sample cleansing pillows. From this it follows that t30and t900the absorption capacity of the sample measure is. the Assu tank in 30 seconds and 900 seconds after initiation, respectively). t30absorptive capacity of the sample in percent is calculated as

[t30the absorptive capacity]/[t1200the absorptive capacity]100%.

Squeezing

The cleansing ability of the cushion to retain fluid when it is subjected to pressure during use, and therefore avoid "squeezing" of fluid is another important parameter of the present invention. "Squeezing" is measured throughout cleansing pillow by determining the amount of liquid that can be absorbed from the sample filter paper Whatman paper under a pressure of 0.25 psi) (1.5 kPa). The squeezing is carried out on the sample, which was filled to capacity with deionized water by horizontal mitilene (specifically, through faylene from the surface of the cushion, consisting of scratching or contact with the surface layer). (One way to obtain the saturated sample is described as "Horizontal Gravimetric Wicking method" in patent application U.S. serial 08/542497 (Dyer and others), filed on October 13, 1995). Containing liquid sample is placed horizontally in the apparatus, is able to apply the relevant pressure preferably with isolierende sample. The amount of squeezing is presented as the weight loss of the liquid to be tested on the weight of the wet sample.

EXAMPLES

This test is carried out in relation to the absorbent cleaning pads (containing an effective amount overabsorbed material sodium polyacrylate, preferably transverse cross-linked sodium polyacrylate).

The test report

The test involves pollution the paint (about 0.5 g mud on the tile after evaporation of the solvent). Each floor area is then cleaned, using 8 ml (printed on 2 tiles) and absorbent pillow size is approximately 14,38 14,38 see Cleaning the pillow is attached to the head on the handle of the MOP by means of "velcro" and wipe the surface of the floor, using motion up and down, going up over the surface one way and then back the other way. The floors are then sorted by the appearance of the cleanup at various time intervals (10, 30 and 60 minutes). The tiles are then re-contaminate and conduct a second test cleanup. In the second test the same contaminated air bags after the first test is used to reproduce (simulate) the load situation of the cleanup and to determine the effect of accumulation. Compare the final results are based on a scale of 0-4, where 0 means no and 4 indicates strong band. In table.1 and 2 show examples of some of the data (the difference between the values of 0.25 is significant).

FIELD: medicine.

SUBSTANCE: antimicrobial wipe, which contains a polymer coating consisting of a synergetic combination of ingredients in order to provide controlled release of the antimicrobial agent and good antimicrobial efficacy. One of the ingredients is a high-molecular polyamidoamine agent controlling antimicrobial agent release. By reason of its polycationic nature, the agent controlling antimicrobial agent release is able to attach to a wet wipe, which generally consists of fibres with a negative surface charge (e.g. of cellulose fibres). The agent controlling antimicrobial agent release may be applied in the binding centres on the wipe and inhibit antimicrobial agent attachment that promotes supplying it into a bactericidal solution for microbial de-contamination of the desired surface. Intensifying the attachment of the agent controlling antimicrobial agent release to the wipe is ensured by cross-linking of polyamide with its molecular mass supposed to be increased that makes it possible to form a structure mesh, which is physically attached to the wet wipe and blocks the antimicrobial agent attachment thereto. Besides, polyamidoamine is amidated so it contains secondary and/or tertiary amides. The polymer coating also contains an agent modifying a microbial cell membrane permeability to increase the efficacy of the antimicrobial agent when in use. More specifically, the polycationic materials are especially suitable for increasing a cell surface permeability with no negative effect on a polyamidoamine ability to release the antimicrobial agent inside the wipe.

EFFECT: higher efficacy of the antimicrobial agent when in use.
