Prior art Absorbent personal hygiene products include such products as diapers, training pants, feminine hygiene products such as sanitary napkins, pads and tampons, garments and devices for people suffering from urinary incontinence, wound dressings and the like. The simplest model of such products typically includes a layer facing the body, an outer layer and an absorbent inner layer located between the layer facing the body and an outer layer. Typically, the layer facing the body, and the outer layer sealed around the perimeter so that they have sealed absorbent layer, thus allowing him to catch and retain any liquids contained in the absorbent layer. Depending on the model-specific absorbent articles may also be included other components. Thus, the product may contain such items as elastic side details, confining fluid barriers, clasps and other permeable layers or holding liquid materials.

Previous items personally is oishii patterns. In such cases, the boundary between adjacent layers is quite clear, often marked by the presence of adhesive that is used to hold the layers together, giving a layered structure. Separate each layer and bonding them together with obtaining the layered structure is expensive technique requiring the involvement of many different pieces of production equipment. This method allows to obtain material for personal hygiene items, with a clear distinction between each layer at the interface or boundary, which may lead to a decline in the rate of transfer of fluid between adjacent layers.

Therefore, the object of this invention to provide a material for use in personal hygiene, which does not require many stages when it is received. Another object of this invention to provide a material for personal hygiene, in which the adjacent fibrous layers have a fuzzy boundary, mixed and entangled fibers in order to improve the transfer of fluid between adjacent layers.

Definitions the Term "disposable" means that the products are thrown away after use and cannot be washed or reused.

The terms "front" and "rear" ispolnie, which takes underwear on the owner.

The term "hydrophilic" refers to fibers or surfaces that are wetted by water liquids that come into contact with the fibers. The degree of wetting of the materials, in turn, can be described by terms such as wetting angle and surface tension of the contacting liquids and materials. The equipment and techniques used for measuring the wettability of particular fiber materials, can be represented by a Cahn SFA-222 Surface Force Analyzer System or essentially equivalent system. When measured with this system, fibers having boundary wetting angles less than 90oare referred to as "wettable" or hydrophilic, while fibers that have a boundary wetting angles equal to or more than 90oare referred to as "non-wetted" or hydrophobic.

The terms "inner" or "outer" refer to positions relative to the center absorbent subject, and particularly transversely and/or longitudinally close or remote from the transverse and longitudinal center of the absorbent product.

The term "layer" when used in the singular can have the dual meaning as a single element or multiple element which may take the internal shape of the vessel in which it is located or infused.

The term "transmission fluid" means the fluid can move from one layer to another layer or from one location to another within the same layer.

The terms "longitudinal" and "transverse" have their ordinary meaning. The longitudinal axis lie in the plane of the product, which is flat and fully stretched, and generally parallel to the vertical plane which bisects a standing user on the right and left halves of the body, and at the moment the product is to the consumer. Transverse axis lying in the plane of the product and generally perpendicular to the longitudinal axis. The product in the longitudinal direction is longer than in the transverse direction.

The term "particles" in the context of this invention refers to any geometric forms, such as, but not limited by them, spherical grains, fibers or filaments, a flat surface or a rough surface, sheets, tapes, ropes, threads and the like.

The term "spray" or its variants refers to the thrown with the force of liquid or in the form of a stream or in the form of twisted fibers or sputtered particles through the orifice, nozzle or the like, by pressure of air or other gas, with the use of the fibre" refers to fibers, formed of at least two polymers extruded from separate extruders but twisted together for one fiber. Conjugated fiber is sometimes referred to as multi-component or two-part fiber. The polymers are usually different from each other, although conjugated fibers can be monocomponent fibers. The polymers are essentially permanently located in certain areas across the fiber cross-section and elongated along the length of the conjugated fiber continuously. The configuration of such a conjugated fiber may represent, for example, the structure of the sheath/core, in which one polymer is surrounded by another, or the structure side by side, the structure of the "pie" or structure "Islands in the sea". Conjugated fiber is described in U.S. patent 5108820 Kaneko et al., U.S. patent 5336552 Strack et al. and the U.S. patent 5382400 Pike et al. In conjugated fibers polymers may be present in ratios of 75/25, 50/50, 25/75, or in any desirable proportions. Fiber can also have a shape, such as described in U.S. patent 5277976, Hogle et al. and 5069970 and 5057368, Largman et al. fully incorporated here by reference, which describe fibers with unusual shapes.

The term "two-part of the same extruder in the form of a mixture. The term "mixture" is defined above. The two-part fiber does not have the various polymer components that are permanently located in a relatively specific zones across the cross-section of the fiber and the various polymers are usually not located along the entire length of the fiber, instead, usually derived fibrils or protofibrils are chaotic. The two-part fiber is sometimes referred to as multicomponent fiber. Fibers of this General type are also described in U.S. patent 108827 Gessner. Conjugated and the two-part fiber is also described in the textbook of Polymer Blends and Composites by John A. Manson and Leslie H. Sperling, copyright 1976 by Plenum Press, a division Plenum Publishing Corporation of New York, ISBN 0-306-30831-1 pages 273-277.

"The laying of the air" is a widely known method, which can be obtained non-woven fibrous web. When laying air bundles of small fibers having typical length of about 3 to about 19 millimeters (mm) are separated and fond in the supply air stream and then applied to form the lattice, usually with the help of vacuum. Random fibers are then connected with one another by using, for example, hot air or spray glue. Stacking air is described, for example, in Patan the UNT 853006260 and the application for patent in the UK 2191793.

The term "personal care items" refers to diapers, training cowards, absorbent underwear, hygiene items for adults suffering from incontinence, the bandages and feminine hygiene.

The term "feminine hygiene" refers to sanitary napkins or pads.

The term "impact" refers to the area or position on the subject of personal hygiene, which usually fall excretion from the body of the consumer.

Methods of test material Size (thickness). The size of a material is a measure of thickness and is measured at a pressure of 0.05 psi (0,0035 kg/cm2) using a device for measuring the volume Starret in millimeters.

The density. The density of a material is calculated by dividing the weight per unit area of the sample in grams per square meter (g/m2) the volume of the sample in millimeters (mm) while for 68.9 Pascals, and multiplying the obtained result by 0.001 to get the value in grams per cubic centimeter (g/cm3). Appreciate the three sample and calculate the arithmetic mean of the density.

Detailed description of the invention the Absorbent personal care items include such items as what I underwear and tampons, garments and devices for people suffering from urinary incontinence, wound dressings, and so forth. The simplest model of such products typically includes a layer facing the body, an outer layer and an absorbent middle layer located between the layer facing the body and an outer layer. Usually the gasket adjacent to the body, and the outer layer sealed around the perimeter so that they have sealed absorbent layer, thus allowing him to catch and retain any liquids contained in the absorbent layer. Depending on the model-specific absorbent articles may also be included other components. Thus, the product may include such items as elastic side details, confining fluid barriers, clasps and other permeable layers or holding liquid materials.

Discussion of the materials for personal hygiene items contained in the patent application of the same applicants, with the same registration date, as this application, with the number on the register of patent attorney 13303.10. A discussion of how to obtain application materials 13303.10 can be found in the patent application of the same applicants under joint consideration with the number on the register Ah personal hygiene, which is produced in such a way as to obtain the fuzzy edges or joints between adjacent fibrous layers. Previous personal hygiene items were made from materials that were obtained separately and then combined together with obtaining layered coating. In such cases, the boundary between adjacent layers was relatively clear and specific, often marked by the presence of adhesive that was used to hold the layers together with obtaining the layered structure.

The material of this invention preferably receive according to the method of laying the air, in which the fibers are suspended and transferred to the gas stream, preferably air, is applied to the substrate with a receiving layer. The material of this invention obtained from several layers that are arranged in series. Such a serial arrangement of materials is possible through the use of a number of units for stacking air. In this process, the fibrous layers are not obtained separately, separately stable and folded together with the receipt of the layered structure, and the one on top of another. Although all of the material must, of course, be uniformly stable, OTDELENIE, which, if it is activated with heat, obviously, requires heat treatment after deposition of the fibers.

The individual fibrous layers of the material of the present invention contain fibers that are mixed and confused with the fibers of adjacent layers when laying air. This aspect of the laying of the air and the usual absence of adhesive between adjacent layers gives the boundary or interface between adjacent layers, which is not clear and specific, but rather is implicit.

The receiving material through the installation of air from a number of units is much more cost effective than obtaining separate layers and then merge them to produce a layered structure, and thereby reduce costs to the final consumer.

The material of this invention has a layer facing the body, optional layer, the conductive liquid, the layer that holds the liquid and the layer facing to the garment. The material may also include distributing layer or other optional layers to provide specialized functions.

The layer facing the body, sometimes referred to as the gasket facing the body, or the upper layer. In the direction of thickness of the product which is the first layer, contact with the liquid or other secretions of the body of the consumer. The layer facing the body, also serves to isolate the users ' skin from liquids held in the absorbent structure, and therefore it should be flexible, soft and not irritating.

The layer facing the body, can have a weight per unit area, for example, from about 10.0 grams per square meter (g/m2) to about 100 g/m2and a density of from about 0.05 grams per cubic centimeter (g/cm3) to about 0.5 g/cm3. The layer facing the body, contains synthetic fibers and binder in a ratio of from about 90/10 to about 0/100, more preferably from about 50/50 to about 20/80, and more preferably about 30/70. It should be noted that the preferred fibrous binder material rather than a liquid binder, especially in those cases when it contains more than 10%.

The surface layer facing the body, can be treated with a selected amount of surfactant, such as about 0.28 per cent surfactant Triton X-102, or processed in any other way to improve the desired level of wettability and hydrophilicity. If you use a surfactant coating, application using brush device and the like, before applying the next layer.

The layer holding the liquid, the present invention should absorb fluid from the adjacent layer facing the body in a controlled way, so the liquid was kept not in contact with the body. Suitable retaining materials for this invention should have a weight per unit area of from about 50 to about 250 g/m2a density of from about 0.05 to about 0.5 g/cm3. The retaining material contains a binder material, synthetic fibers and natural fibers. The binder material should be present in an effective amount, typically from about 3 to about 15%, or, more preferably, about 10%. Synthetic and natural fibres, not taking into account the binder material may be present in a ratio of from about 0/100 to about 50/50, more preferably from about 10/90 to about 20/80, and most preferably about 40/60. Although any of the layers of this invention may optionally contain overabsorbed, the layer that holds the liquid, is the most appropriate layer for its content. This layer may contain from 0 to 85 wt.% overabsorbed, which should be included as natural is in can be anything although especially useful additional layer is the second confining layer. This second holding layer may be located between the first holding layer and the layer facing to the garment, and may contain a binder material in an effective amount and not given binder, about 75% natural fibers and about 25% of the fibers overabsorbed. As noted above, overabsorbed should be considered as the natural fiber in the calculation of the ratio of fibers in the layer, thereby obtaining the ratio of synthetic and natural fibers in this layer 0/100, not given binder.

Layer facing to the garment, also called the wrong layer or outer cover layer, is the most remote from the body of the consumer layer. The outer coating layer is traditionally produced from a thermoplastic film such as polyethylene film, which is essentially impervious to liquid. The function of the outer cover layer is to prevent wetting or soiling the clothes of the user, bedding or other materials in contact with the subject of personal hygiene, secretions of the body contained in the absorbent structure. Although Vasyliev) to about 5.0 mils (0,12 mm), preferably, the outer coating layer was developed as an integral part of the material of the present invention. In this case, it is preferable that the layer facing to the garment, or the outer covering layer had a weight per unit area of from about 10 to about 100 g/m2and contained synthetic fibers and binder in a ratio of from about 50/50 to about 0/100.

The outer coating layer may be embossed and/or have a matte finish to give it an aesthetically pleasing appearance. Other alternative designs for the outer cover layer include woven and non-woven fiber fabric, which is sourced or processed in such a way as to give the fabric the desired level of impermeability to liquids, or layered materials obtained from woven and non-woven cloth and thermoplastic film. The outer cover material may not be permeable to vapors or gases, micro-porous "breathable" material which is permeable to vapors or gases, but essentially impermeable to liquid. The permeability can be attached to the polymer film by using, for example, the use of fillers in the composition of the polymer film, extruding competitiveprices degree, and thus, breathable (air-permeable) film. Usually the more filler and the higher the degree of stretching, the greater the permeability. External coatings also serve as mating parts for mechanical fasteners in the case, for example, if the non-woven fabric is an external surface.

An optional layer that transmits fluid, also designated as the transmissive layer, usually located in close, allowing the transfer of fluid, the contact between the layer facing the body, and another layer, such as layer distribution or fluid retention. Layer, the transmitting fluid, or permeable layer allows fluid to move through it is usually in the Z-direction, i.e. away from the body and in the direction of the garment. The transmissive layer generally adjacent to the inner (invisible) surface layer facing the body. It is preferable that the transmissive layer had a density of about 0.05 g/cm2to about 0.5 g/cm2and the weight per unit area of from about 10 to about 100 g/m2. The transmissive layer may be a layer composed of synthetic fibers, a binder material and natural fibers, where the binder material is present in an effective and from about 40/60 to about 10/90.

Optional distribution layer may be located above (towards the body of the user) layer, holds the liquid, and should facilitate the passage of the liquid from the place where she originally gets to the point where it is desirable holding it. The layer of liquid distribution therefore, in addition to the passage of the liquid through it in the Z-direction contributes to its advancement in the X and Y directions. The distribution shall be made with reasonable speed so that the area of liquid, usually perineal region, was ready for the next arrivals. The time between the receipt of the discharge may vary from several minutes to hours, usually depending on the age of the consumer and purpose of the subject of personal hygiene. To achieve this transport function of the distribution layer should have a high index of capillary pressure. Capillary pressure in distributing the materials is measured simply by using equilibrium vertical wicking of 8.5 g/l saline solution, and this indicator must be above 15 see Test on leaking carried out as follows: place the end of the material vertically in a physiological solution, wait until t is which can be obtained from the distribution layer, can be made from synthetic and natural fibers with a small amount of binder.

Synthetic fibers include fibers derived from polyamides, polyethylene terephthalate, the hydrated cellulose fibers, polyolefins, such as polypropylene, cellulose hydrate Lyocel, and any other suitable synthetic fibers, known to specialists in this field. Such synthetic fibers can include conjugated two-part and homopolymer fiber staple or different lengths, and mixtures of such fibers with other types of fibers. Synthetic fibers can also include kosmotrope for decomposition product, as described below.

Natural fibers include cellulose such as wood pulp, cotton and so on. Cellulose include standard pulp of soft wood in the form of fluff, such as Coosa Mills CR-1654 from Kimberly-Clark Corporation, does not contain formaldehyde cellulose with the addition of increasing volume (HBAFF), commercially available from Weyerhaeuser Corporation of Tacoma, WA, which is a crosslinked cellulose fibers from southern soft wood with improved coefficient of moisture, chemically cross-linked fibers, such as Weyerhaeuser NBH416. HBAFF passes khimicheskogo stiffness in wet and dry condition and elasticity. Other suitable cellulose is cellulose Buckeye HP2, and another is cellulose IP Supersoft from International Paper Corporation. Suitable hydrate cellulose fibers are fibers Merge 18453 1.5 denier from Courtaulds Fibers Incorporated from the Axis, Alabama.

Binder materials include fiber, liquids, or other binders that can be activated by heating. Exemplary binder materials include conjugated fibers of polyolefin and/or polyamide and liquid adhesives. One suitable binder material is a conjugated fiber type "shell/core", commercially available from Trevira Inc. (former Hoechst-Celanese), PO Box 4, Salisbury, NC 28145-0004 under the trade designation T-255, although experts know many other suitable binder fibers are produced by many manufacturers, such as Chisso and Hercules Inc.

Issue attention is the production of personal hygiene products that are "rinse-off (down) or which can be thrown in the regular toilet and which are safe for disinfecting or municipal wastewater treatment plants. One of the ways to increase the Biodegradability of personal hygiene is to produce pieces that quickly decompose under the conditions existing at such stations. There are many mechanisms to obtain such a result, though most of them are not applicable or are not reliable and result in damage to the product at inopportune moments or unrealistic time requirements time that passes before the collapse of the product.

One of the mechanisms that can be used to initiate decomposition in water within a reasonable period of time, is the sensitivity to ions, where the term "ion" is given its ordinary meaning of the atom or molecular bound group of atoms that has gained or lost one or more electrons and therefore received a negative or positive charge. Certain polymers containing acid (R-COO-) the components that are held together by hydrogen is about a high concentration of ions, such as urine, the polymer still remains relatively untouched. However, when the same polymer is adjudged to be in large quantities of water with low content of ions, which may be in the toilet, the ion concentration is reduced, and the hydrogen bonds begin to break down. Once this occurs, the polymer starts to decompose in the water. Materials having such characteristics, known as kosmotrope (see, for example, U.S. patent 4419403 Varona, which is fully incorporated here by reference).

In conjugated fibers, for example, the polymer of the first component, which is stable in liquid media with high concentration of ions (for example, the urine of a child or an adult and menstrual periods), may represent a sulfonated polyesters, marked AQ29, AQ38 and AQ55 from Eastman Chemical Company of Kingsport, Tennessee. The polymer Eastman AQ 38 consists of 89 mol.% isophthalic acid, 11 mole% nutritionposition acid, 78 mol.% diethylene glycol and 22 mol.% 1,4-cyclohexanedimethanol. It has a nominal molecular weight of 14,000 Daltons, an acid number less than 2, a hydroxyl number less than 10 and a glass transition temperature 38oC. Other examples can be a mixture of poly(vinyl alcohol) or copolymers of the RA, mixed with polyacrylic or methacrylic acid. Polymers Eastman stable in liquid media with high content of ions, but rapidly degrade in sewage water during flushing (excess water), decreasing the concentration of ions. The Eastman polymers can be combined with the second polymer component with a higher temperature melting point, such as polyethylene.

Other first polymer components, stable at high ion concentrations, include initiated, water dispersible polymers". This implies that when the first component of the conjugated fiber comes into contact with the originating component, such as, for example, sulfate ion or chloride ion, at the first level of concentration present in ordinary tap water, the polymer forming the first component is dispersed or degraded no more than 30 minutes. However, when the first component of the conjugated fiber comes into contact with the same initiating component at the second, higher level of concentration normally present in body fluids, such as child or adult urine or menstrual flow, the polymer forming the first component remains stable and is not dispersed.ednie polymers, such as complex sobolifera polymers, available from National Starch and Chemical Company under the trade designations 70-4395 and 70-4442. Conjugated fiber having a first component containing initiated, water dispersible polymer is not sensitive to the presence of a particular initiating component when the concentration levels present in the urine or menstrual flow, while they are very sensitive and easily dispersed in a period of time not exceeding 30 minutes in the presence of the same initiating component at another, lower level of concentration, usually available in excess of tap water, such as in the toilet. Thus, fibrous material obtained from or comprising initiated, dispersible in water, the polymers are not sensitive decomposing contamination from liquids coming from the body, such as urine or menstrual periods at the same time, getting in ordinary tap water, they tend to disintegrate, as the dispersed first component of the conjugated fiber.

In addition, it is preferable that all the material has been embossed preferably from the side facing the body. Embossing may be small, eno liquid layer and distribution layer, and the layer holding the liquid. The embossing pattern may be selected so as to maximize the compaction of the material, which improves the penetration of the liquid and its dispersion through the product and distribution of liquid along the front to rear axis. Embossing may also provide visual cues to the consumer stating that the product is almost full and should be replaced, and embossing can be used for aesthetic purposes. Examples of suitable relief patterns are given on the drawings. In Fig.1 shows the embossed pattern of the subject of personal hygiene, designated as form of the sinusoid of Fig.2 shows the embossed pattern of the subject of personal hygiene, is designated as the shape of the shell.

Although there have been described only certain embodiments of the present invention, the person skilled in the art will understand that there are many possible modifications of the embodiments that fall within the scope of new ideas and advantages of this invention. Accordingly, all such modifications are included in the scope of the present invention and defined in the claims. In the claims the items related to the devices, and functional items cover the described destructure. Thus, although a nail and a screw may not be structural equivalents, because the nail is used cylindrical surface for connecting wooden parts together, whereas in the screw used screw surface, from the point of view of connections of wooden parts, a nail and a screw may be equivalent structures.

Further, it should be noted that any patents, patent applications and publications referenced in this description included in it completely.
