The present invention relates to the field of textile products non-woven materials, and applied it to the manufacture of nonwoven material, especially to the normal products of nonwoven material for various applications, e.g., for use in the household and personal care products.
Wet or soaked wipes are widely used in several areas. For example, cloths (rags) of nonwoven material used for cleaning, and they can be impregnated with waxes or other cleaning solutions. Wet wipes are also used for personal hygiene, and they can contain detergents, perfumes funds or even cosmetic lotions or creams.
These products are usually made from raw materials based on cellulose (100% cellulose or, in any case, with a high content of cellulose, e.g. viscose, cotton etc having absorbent properties.
High absorptive capacity is a necessary property of the material, intended to moisturize and retention of sufficiently large quantities of desired substances type (detergent, cosmetics, etc.). However, another important property of these products is the ability to release such a solution of the substance and transfer it to the surface to be treated. RAS�e known materials based on cellulose, as described above, did not meet this requirement, as the solution of the substance was strongly resist cellulose fiber so that only 50-60% solution of the substance is released during the application.
The consequence of such partial release of substance solution was not only the low efficiency of the product and increase value for consumers, but also that resulting as a result, the waste materials were still soaked potentially polluting substances.
WO 2005/116317 discloses a nonwoven substrate to obtain the wipes, which is designed for dry cleaning a variety of substances.
The aim of the present invention, therefore, is the creation of a wet product of nonwoven material, impregnated with a substance having a high absorptive capacity and a high potential for release of the substances and transfer it to the surface.
An additional objective of the invention is to provide a method of manufacturing mentioned textile product.
These objectives were achieved through the use of a wet product of nonwoven material, impregnated with a substance, characterized in that said nonwoven material is bonded fibrous cloth having hydrophilic properties, or fibrous fabric, which has g�ProfiLine properties by treatment moisturizing additives, and through the use of a method of manufacturing the above-mentioned product, as defined in the appended claims, the definitions of which are an integral part of the present description.
Non-woven fabric to be used according to the present invention may contain fiber or continuous filaments, or a mixture thereof.
Continuous filament can be obtained through use of the method of molding with the use of a Spinneret containing 1 to 5 holes, preferably 2-3 holes.
Continuous filaments can be produced in the form of a single component of filaments or in the form of a bi-component, three-component or multicomponent elementary filaments.
In one embodiment of the fiber contains more than about 90% synthetic fiber, more preferably more than 95% synthetic fiber. In a particularly preferred embodiment of the fiber used for the manufacture of a fibrous fabric containing almost 100%, and preferably 100% synthetic fiber.
In one embodiment, the implementation of continuous filaments contain more than about 90% synthetic continuous filament yarns, more preferably more than 95% of synthetic continuous filament yarns. In a particularly preferred�tive embodiment of the continuous filaments used for the manufacture of fibrous webs, containing nearly 100%, and preferably 100% synthetic continuous filament yarns.
In one embodiment, the implementation of synthetic fibers (staple fibers) and/or continuous filaments made of a material selected from the group consisting of: polyester, polypropylene, polyamide, acrylic substances and their mixtures; preferably they consist of 100% polyester or 100% polypropylene.
In one embodiment, the implementation of synthetic fibers and/or continuous filaments made of a material selected from the group consisting of: polyester, polypropylene, polyamide, acrylic substances and their mixtures; preferably they consist of 100% polyester or 100% polypropylene and contain from 5 wt.% to 30 wt.% bicomponent fiber from the complicated polyester/polyethylene; polypropylene/polyester; polyester terephthalate (PET)/polyester PEN; nylon-6,6/PCT polyester; copolyamide nylon-6; polylactic acid/polystyrene; acetal-soluble polyurethane or copolymer of polyester and high density polyethylene (HDPE)/foundry of low density polyethylene (LLDPE).
The term "bicomponent fiber" means a fiber obtained by joint extrusion of two different polymer�. It is also called "dual fiber". Not limiting the scope of the invention examples of bicomponent of filaments include the configuration: "sheath-core" (concentrically or eccentrically); "side by side" (equal or unequal parts); and "Islands in the ocean". According to the proposed invention are particularly suitable bicomponent fiber with the structure of the "sheath-core" and "side by side".
In one embodiment, the implementation uses HOLLOFIL fiber*, separately or in a mixture with the above-mentioned fibers or continuous filament fibers. HOLLOFIL* is a trademark of hollow fiber made of a modified silicone 100% polyester (Dacron, polyethylene terephthalate), manufactured by the DuPont company.
In one embodiment, the implementation proposed in the invention, the nonwoven material is bonded fibrous fabric containing more than one BATT, preferably from 3 to 9 procesov. Through the use of a number of procesov in the range stated above, get more isotropic textile structure and accordingly providethe maximum possible uniform distribution of the fibers in space, resulting in providethe maximum possible surface contact of the fiber with water. Thus, water droplets are adsorbed structure in low prices� spaces the resulting chaotic fiber distribution.
Textile product according to the invention typically has a surface density (ratio of mass to surface area) comprised between 20 g/m2to 150 g/m2,preferably from 20 g/m2to 50 g/m2or more than 25 g/m2but less than 35 g/m2.
Bonded fibrous fabric according to the invention can be obtained in various ways known to specialists in this field, for example, by the methods provided in subsequent descriptions of the variants of the implementation.
In the first variant of implementation proposed in the invention, the fibrous web may be bonded by a well-known way entanglement of the fibers by the liquid jets and the thus obtained fibrous cloth, called "Spunlace". This method ensures the entanglement of fibers in the fibrous cloth, moving perforated or patterned mesh conveyor belt, by the impact of jets of water under high pressure. The water pressure usually increases in the direction from the first injector to the last; pressure jets of water directed on fibrous cloth, is up to 15.47 kg/cm2(2200 psi). Blows jets of water on the fibrous fabric cause entanglement of the fibers. Released water UD�collected by suction from beneath the conveyor belt for the exception of the Gulf of fiber web by water. The free water trapped in the pores between the fibers is then removed by drying.
After the entanglement of the fibers by the liquid jets may be followed by optional treatment with hydromineral according to conventional technologies. These provide increased softness of the product and increase its volume.
In another embodiment of the binding fiber web is carried out by so-called dry method of formation. The dry process of the formation may include providing fiber web, usually tissue carrier containing, as indicated above, from 5 wt.% to 30 wt.% bicomponent fibers as described above, and the direction it in the dryer, in which the material is subjected to heating to a temperature in the range from 120°C to 200°C, usually within 3 to 15 C. Under the influence of high temperature polymer with a low melting point included in the bicomponent fiber is melted, resulting in formation of point bonding throughout the fibrous web. This method, known as method of stitching through procosa <hot> air favorable if you want to obtain a softer and thicker fibrous cloth, especially if you use a bicomponent fiber with the structure of "side by side". It should be noted that with this softer material structure polysalts� adsorptive capacity and ability to release liquid, what is important for the present invention.
In yet another embodiment proposed in the invention the fibrous fabric fasten well known to chemically bond. In this case, the fibrous fabric is treated, for example by impregnation, printing, spraying, powder-coating or foam material using a solution or in solid form the latex polymer, or binder, in amounts constituting in the range of 5wt.% up to 60% by weight. The thus treated fibrous cloth is then subjected to heat-setting, for example, by heat treatment. Suitable binders are selected from: styrene butadiene rubber; vinyl copolymers; vinyl acetate; acrylates modified with styrene, or vinylacetate; polyvinyl chloride. In the binder composition may include additional ingredients, for example: surfactants (to improve the adhesion of the binder, stability, and the ability to transform in a foamed state); substances for the formation of an external cross-linking; protivovospalitel (to minimize foaming during processing); repellents; salt (to impart flame retardant properties and to impart antistatic properties); thickeners (for adjusting the rheology of the bonding liquid); catalysts (with�of sobstveny cure and cross-linking); acids and bases (for pH regulation binder); dyes and pigments; fillers (to reduce stickiness of the binder and to reduce the cost); optical brightening agent (to increase white); excipients to facilitate crosslinking (for lubrication).
In another embodiment of the binding fiber web is carried out needle-punched method. Provide fibrous cloth, usually from the BATT of staple fibers. The fiber in the fabric mechanically mix through its perforations with metal needles with notches, which are mechanically moved at high speed reciprocating forward and backward through the fibrous fabric, in a direction essentially perpendicular to the plane of the fiber web. This movement of the needles with notches cause entanglement of fibers in the fibrous sheet with adjacent fibers, turning the fibrous web in associated, durable structure.
As mentioned above, the product according to the invention comprises a bonded fibrous fabric having hydrophilic properties (due to the included in the composition of the polymer), or a fibrous fabric, which impart hydrophilic properties by treatment moisturizing additives.
Fibrous fabric having a hydrophilic with�the properties, may be a fibrous fabric, which was subjected to a hydrophilic surface finishing treatment. Such nonwoven materials are available for purchase on the market. However, in this case, the method of entanglement of the fibers by the liquid jets to create a bonded structure, as in the processing of the water jets wash away the hydrophilic finishing agents. Thus, when using such material, it is preferable in the dry method of forming and bonding, or chemical bonding method.
Fibrous cloth, which has hydrophilic properties by treatment moisturizing additives, can be obtained by the methods described below.
Moisturizing treatment can be performed using both the previously received product "Spunlace" and other bonded fiber web; a moisturizing treatment can also be done with their manufacturing process.
If you use the method of entanglement of the fibers by the liquid jets to bond the fiber web, moisturizing treatment is performed after the entanglement of the fibers by the liquid jets and before drying in the drying chamber.
Moisturizing additives are the substances commonly used in this field, for example: cationic, anionic or nonionic surfactants.
In preferably�m variant implementation as a moisturizing ingredient used anionic surfactants. Mentioned anionic surfactant is preferably an alkyl-polyglucoside ester. In one embodiment of the above alkyl-polyglucoside ester is selected from: companylogos sulfosuccinate, denetria, companylogos citrate denetria, companylogos sodium tartrate or mixtures thereof. These surfactants are known under the brand names EUCAROL® AGE SS, EUCAROL® AGE EC and EUCAROL® AGE ET, respectively, and are available to purchase from the company LAMBERTI spa. During testing, the application of this supplements showed greater efficiency from the point of view of giving an absorbent capacity of the finished product at low dose. In fact, with the small dose administered supplements is an increase in the quality of products in comparison with products obtained through the use of large doses, which is shown in more detail below.
Method moisturizing treatment can be selected from the methods used in common practice. These methods, among others, are as follows:
- coating: mixture product is applied by spraying on the fiber;
- coating: mixture product is applied with a pin shaft, which distribute the products on the surface of the fiber web;
- print: method similar to the coating, but they use a printing machine;
- drunken�a: fibrous cloth, either already formed, or at an intermediate stage, immersed in a mixture of the selected products, then the excess amount of food press in a calender or similar devices;
coating foam: mixture of chosen ingredients is stirred with a gas (usually air) in a high speed mixer until then, until the mixture turns into foam, and foam is then applied on fibrous cloth, using conventional techniques for coating.
Dosing moisturizing additives change depending on the fiber characteristics of nonwoven fabric (density, fiber distribution, etc.) and the desired level of adsorption (this refers to the amount adsorbed, retained water and the duration of the process of adsorption, capillarity).
Impregnation, followed by a spin in the calender, is the preferred method of treatment, has the advantage over other methods, namely that it allows you to more evenly distribute the moisturizing additive to all parts of the fibers and the nonwoven material. In this case, the concentration of the composition of the bath must be in the range from 1 g/l to 10 g/l, preferably from 1 g/l to 5 g/L. for Example, if the solution is used at a dosage of 1 g/l, and absorption no�anago material is 100% it turns out that the number of carbon additive is 1%.
In this case, the fibrous fabric is passed through the bath with a moisturizing agent in concentrations described above, and then fed to the calender for pressing, then served in the drying chamber for drying.
The release calender should be set so that the pressing has been calibrated, i.e. that the pressure was such that there was very small amount of liquid, so finding the material in the drying chamber was as short as possible. At the same time, the pressure should not be so high as to fibrous cloth was pressed in the calender that would lead to modification of the structure of the nonwoven material. After several tests it was found that the best results were obtained at a pressure ranging from 4 bar to 8 bar, preferably about 6 bar, with its application to the fibrous cloth is submerged in the solution moisturizing additive in the above concentrations.
After extraction in the calender, non-woven material is directed into the drying chamber. The temperature in the drying chamber depends on the speed of the passes of the product through the chamber and should be adjusted so that it is ensured complete evaporation of water. For example, if a product with a surface density of 55 g/m2transported �ri manufacturing at a speed of 150 m/min, the temperature in the drying chamber must be set to the value of approximately 120°C for complete evaporation of the water.
Proposed in the invention, the fibrous web may contain various additives. After several tests it was found that the quality of the finished product, especially from the viewpoint of softness and absorption capacity depends on the fraction of additives introduced into the mass of the original fiber.
Manufacturers are injected into a mass of synthetic fibers or continuous filament yarns are several types of additives, for example: the sizing additive to impart flatness and to ensure easy processing AIDS; anti-static additive to prevent harmful electrostatic currents that can degrade the quality of the product or in the worst case, lead to reduced performance of the machine; a hydrophilic additive; antifoaming additives to prevent formation of foam, especially at the stage of fiber entanglement jets of liquid.
Synthetic fibers or continuous filaments, which can be used for the purposes of the present invention must contain a very small fraction of the original supplements. For example, a suitable proportion, ranging from 0.1 wt.% to 0.2 mass%. Examples of these fibers are: 100% fiber from the complicated polyester Dupont, Motefibre, Hochst, Catalana, etc.
In one embodiment, the implementation proposed in the invention the nonwoven fabric, in addition to handling moisturizing additives, also treated with antifoaming additives to control the surface tension of the solution moisturizers. Examples mentioned antifoaming agents are additives based on silicone. Preferred antifoaming agent composition of the brand HANSA SP®, available for purchase from the company HANSA spa. Antifoaming substance can be applied to the nonwoven fabric using various processing techniques, as described above. Antifoaming substance successfully applied by impregnation, along with a wetting agent, i.e. prepare a single bath containing both additives: wetting and antifoaming. A solution of antifoaming substances, which was successfully used for the manufacture of the product proposed in the invention, has a concentration comprised between 1 g/l to 7 g/l, preferably about 2 g/L.
As mentioned above, antifoaming substance is used to regulate the surface tension of moisturizing substances, i.e. to control the volume of the formed foam material in its application. Available for purchase is also hydrophilic additives that malefic�ivny, although they are weakly foaming substances, and therefore it is required to use them in large doses. As mentioned above, as the original Supplement, and hydrophilic and antifoaming additives which are introduced during manufacturing, degrade the quality of the finished product when they are added in large doses. Thus, the best choice, proposed in the present invention, the use of fibers with a low content source supplements to which is added a reduced number of very highly foaming wetting agents, especially alkyl-polyglucoside esters, for example, as described above, and at the same time also reduced the number of antifoaming additives.
As mentioned above, the product of nonwoven material in the form of a fiber web according to the invention is obtained by impregnating substance mentioned bonded fiber web possessing hydrophilic properties, or fiber web, which impart hydrophilic properties by treatment moisturizing additives, as described above.
The term "substance" when used in this description means a solution, suspension, gel, emulsion or other moist composition of matter for personal hygiene, for use in the household or for local processing in m�medical purposes or combinations thereof, as it may be in practice.
Not limiting the scope of the invention examples of substances for personal hygiene are: solutions or lotions for personal hygiene and/or sanitation, skin creams, lotions, waxes, creams or tanning lotions, sunscreen formulations, insecticides, repellents, deodorants, perfumery means, antibacterial agents, antiviral and/or antifungal compositions, lotions or solutions for removing makeup and cosmetic products in General.
Not limiting the scope of the invention examples of substances for use in the household are: solutions or emulsions detergents, waxes for ceramic or wooden floors, waxes for wood furniture surfaces, disinfection of surfaces, antibacterial agents, antiviral and/or antifungal agents for use in the household, emulsions for polishing metals, solutions or creams and formulations for cleaning, in General.
Not limiting the scope of the invention examples of substances for topical use in medical applications are: means for disinfection of the skin, means for antibacterial skin treatment, antiviral and/or antifungal agents, compositions for healing wounds and, in General, any medical compounds that m�may be assigned as a means for local use, or composition for cleaning medical installations, apparatus or device.
In particular, if the substance is viscous, which may be in the case of emulsions, suspensions, gels, creams or waxes, it is important that the wetting agent was particularly effective in imparting hydrophilicity of nonwoven material and to facilitate subsequent release of the substance during use. In one embodiment, the implementation was successfully used non-woven material containing these viscous substances, processed alkyl-polyglucoside ester. More preferable to use companylogos sulfosuccinate, denetria, thanks to its thinning action.
Use of the substance in the form of a cream, wax or gel is particularly preferred because these forms of the compositions contain lower amounts of water, which is favorable to contain breeding colonies of undesirable microorganisms. In this case, can be used small quantities of biocide additives or even the product may be substantially free of biocide additives.
If the substance is a cream, wax or gel, it is convenient that the viscosity of this substance has declined at a temperature of about 30-35°C, so that it can be easily applied to the human body.
Proposed in the invention, the fibrous sheet can be p�opicana mentioned substance by any known method, of the above moisturizing treatment, provided that the impregnated product of nonwoven material according to the invention will be Packed while it is still wet. In particular, can be successfully used method of applying a substance on the fibrous fabric using suitable nozzles. Impregnation and coating are suitable methods for the introduction of solutions or lotions. For insertion creams and waxes can be effectively used to supply them in the form of a melt, due to the high viscosity of such forms of matter. Proposed in the invention, the textile product may be, for example, in the form of rags, cloth and similar textile materials, napkins, etc.
Textile product obtained according to the invention, is very hydrophilic product, which has a significant adsorption capacity and softness, and it is pleasant to touch, and this property is preserved also after the first application.
In addition, it was unexpectedly found that in addition to this ability of adsorption of aqueous formulations, at the same time, he has a superior ability to release such aqueous compositions under the application of pressure, for example, if the textile material is compressed between the fingers or pressed against the surface to be treated.
It was experimentally defined�but more than 80% vol. or even more than 90% vol. substances released from the product of non-woven material under the application of pressure. The term "pressure" means the normal average pressure applied by the user's hand, when laying the cloth, flap, or other piece of textile material on the surface to be processed.
This amount of released substance is large in comparison with the amount of the released substance, comprising only 50-60% vol. (or even less in the case of waxes/creams), which could be released when using the previously known products of non-woven materials based on cellulose. Not linking this phenomenon with any theory, the authors believe that this is probably happening due to the fact that in the textile material according to the present invention, the fibers or filaments of the fiber web does not absorb the substance which is held only in the cavities between the fibers or continuous filament fibers.
The volume ratio of voids and fibres in the proposed in the invention the textile material is, therefore, an important distinguishing feature. Thus, the observed bulk density of the textile material, defined as the mass per unit volume of the material, where for about�jam take fiber volume and the volume of the cavities, preferably is from 20 g/DM3to 30 g/DM3.
Parameters which can influence the achievement of such low bulk density, are as the diameters of the fibers or of filaments and method used for the entanglement of these fibers or of filaments.
Fibers or continuous filaments preferably have a diameter of from 0.5 to 6.7 dtex dtex, the diameter of continuous filament yarn is preferably from 0.9 dtex to 2.5 dtex, more preferably about 2.0 dtex, while the diameter of the staple fibers is from 0.5 to 3.7 decitex decitex, and preferably approximately 3.3 dtex.
The preferred method of entanglement to increase the amount of textile material according to the present invention is a method that provides the possibility of increasing the thickness of the textile material in the range from 20% to 70%, while maintaining substantially constant surface density. The preferred method of scrambling is bound by prisasyvaniya air. This method has an additional advantage, namely, to exclude the use of water, which, therefore, contributes to the protection of the finished product from microbial growth.
More nodules�but proposed in the invention the product is characterized by a lower time of adsorption of the substance, a greater capacity for retention of this substance, as well as greater ability of the release agent by application of pressure and elevated total softness.
During testing of textile material made as described above, showed a significant adsorption capacity, which remained almost unchanged during use (see Table 1).
Estimate the adsorption capacity was performed according to the standard EDANA 10.4-02 on the method of determining the absorption (EDANA-European Association of manufacturers of nonwovens and disposable products).
In addition, in comparative tests, it was confirmed that proposed in the invention product, at the same thickness, has a high tensile strength in longitudinal and transverse directions and an increased elongation in the longitudinal and transverse directions in comparison with the material, consisting of a mixture of fibers: 50% rayon fibers and 50% of the fibers from the complicated polyester (see Tables 2 and 3).
