Absorbent articles typically include an outer coating made of a layered material containing impermeable to the liquid film, and a nonwoven fabric of hydrophobic polymer fibers. However, such external covering is the difficulty to print fast and economical way, which would provide effective adhesion and stability of ink to abrasion. In particular, it is difficult to obtain good adhesion of the ink to the visible surface of the nonwoven fabric of synthetic fibers.

The need to ensure good adhesion of the ink to the outer covering of absorbent products increases due to the strength requirements of its outer coating. For example, during use, the outer coating of absorbent products may come in contact with oily compounds (for example, baby oil, lotions and the like), which can cause faster erase ink from its surface. When oil composition applied on the skin of the person wearing such a product, or person providing care for him, the ink can be transferred from the surface of a coating on the skin. Thus, the paint cause undesirable leaving spots on the skin, which in turn affects the General appearance of the coating.

To protect the image applied to the outer coating, the images printed on the surface of the underlying p is tochnogo layer of the outer cover, resulting in the overlying polymer layer of non-woven material helps to protect the image from Erasure. Although a non-woven fabric can protect the pattern on the underlying layer, it also reduces the color intensity of the picture that clearly shows the obtained absorbent product. In order to compensate for this loss of color is sometimes a film is applied, the excess amount of ink, which leads to an increase in the cost of materials absorbent products. In addition, such excess amount of ink may require a longer time for drying, which in turn can lead to slower speeds the production process.

In line with this, there is a need to improve the adhesion of the ink to the visible surface of the nonwoven fabric, for example, such that you can use as an external coating of absorbent products.

DETAILED DESCRIPTION of ILLUSTRATIVE embodiments of the INVENTION

Definition

Under used in the context of this application, the term "nonwoven fabric or canvas refers to the canvas, having a structure of elementary fibers or threads which are interwoven, but not in any particular order, as in the case of knitted material. Nonwoven fabrics or webs are produced by numerous methods, such as methods of forming from the melt-blow process, ways of spinning (spunbond) forming from the melt, the production methods associated cloth carding, and the like.

Under used in the context of this application, the term "removed from the melt canvas" generally refers to a nonwoven fabric formed by the method in which the molten thermoplastic material is extruded through a lot of fine, usually circular capillaries of a Spinneret in the form molten filaments into converging high-speed flow of gas (e.g. air), which thins the elementary fibers of molten thermoplastic material to reduce their diameter, which may correspond to the diameter of microfiber. After that, formed from melt blown fibers are picked up by the high-speed stream of hot air and laid on adopts the second surface of the forming fabric, consisting of randomly oriented fibers. This method is described, for example, in U.S. patent No. 3849241 issued Butin, etc. included here fully by reference. Generally speaking, the fibers blown from the melt, can be a microfiber, which are essentially continuous or discrete thin fibers whose diameter is typically less than 10 μm, and when laid on making the surface they usually are in a sticky condition.

Under used in the context of this application the term "spunbond fabric production method" refers to the canvas containing mainly small-diameter fiber. Fibers are formed by extruding molten thermoplastic material is emitted in the form of filaments from a variety of fine, usually circular Spinneret capillary channels with a subsequent rapid decrease in the diameter of the extrudable thread through, for example, pulling them under the action of a stream of air emitted from the ejector and/or with other known technologies spunbond production mechanisms. Spunbond technology for the production of non-woven sheets described and illustrated, for example, in U.S. patent 4340563 issued by Appel and others, and the U.S. patent 3692618 issued Dorschner and others, U.S. patent 3802817 issued by Matsuki and others, U.S. patent 3338992 and 334194, issued to Kinney, U.S. patent 3502763 and 3909009 issued by the Levy, and the U.S. patent 3542615 issued Dobo and others, which in its entirety is included in the scope of this application by reference for all purposes of the present invention. Fiber spunbond production method usually are not in a tacky state when put them to accept the surface. Fiber spunbond production method can sometimes have a diameter of less than 40 microns, and often they have a diameter in the range of about 5 to 20 microns.

Under used in the context of this application, the term "material joint molding", in General, refers to composite materials containing a mixture or stabilized matrix of thermoplastic fibers and a second non-thermoplastic material. As an example, the materials of the joint molding can be obtained by a method in which at least one cylinder of the extruder for fibers blown from the melt, is located near the tray, which serves the additional materials to the sheet during its formation. Such other materials may include organic fibrous materials such as woody or non-woody pulp, containing for example, cotton, rayon, paper recyclables, fluffed wood pulp, superficiale particles of inorganic and/or organic absorbent mother of the crystals, the treated polymeric staple fiber and the like, but are not limited to. Some examples of such materials joint molding is described in U.S. patent 4100324 issued by Anderson and others; US patent 5284703 issued by Everhart and others; and U.S. patent 5350624 issued by Georger and others, which in its entirety is included in the scope of this application by reference for all purposes of the present invention.

Used in the context of this application, the term "multicomponent fibers"refers to fibers that receive at least two components based polymers. Such fibers are typically formed by extrusion from separate extruders but the resulting filaments are combined together with the formation of the single yarn. The polymers in the composition of the relevant component filaments, usually differ from each other, but they can also include individual components are chemically similar or similar polymeric materials. Individual components usually are almost permanently located in certain areas of the cross-section of single fibers and extend continuously along its entire length. Such fibers by the nature of the location of the components relative to each other can be a structure, for example, type "side by side", type "layered cake" or any structure on the ugogo type. Multicomponent fibers and methods for their preparation are described in U.S. patent 5108820 issued to Kaneko and others, U.S. patent 4795668 issued Kruege and others, U.S. patent 5382400 issued by Pike and others, U.S. patent 5336552 issued to Strack and al. and U.S. patent 6200669 issued Marmon and others, which in its entirety is included in the scope of this application by reference for all purposes of the present invention. These fibers and their individual components can also have complex shapes, such as described in U.S. patent 5277976, issued in the name Hogle and others, U.S. patent 5162074 and 5466410, issued in the name of Hills, the U.S. patent 5069970 and 5057368, issued in the name Largman and others, which in its entirety is included in the scope of this application by reference for all purposes of the present invention.

Used in the context of this application, the terms "elastomer" and '"elastic" means a material which, under the action of tensile forces can be stretched at least in one direction (e.g., cross-machine direction) and which upon removal of the tensile force shrinks/restored almost to its original size. So, for example, an extruded material may have a stretched length that is at least 50% greater than its unstretched length in released condition and which will recover within at least 50% of its stretched length after the removal of the Oia tensile strength. As a hypothetical example, one (1) inch sample of a material which can be stretched, at least 1.50 inches and which, upon removal of the stretching force, will give the recovery length is not more than 1.25 inches. It is desirable that the amount of compression or recovery of such elastomeric sheet material comprised of at least 50% and even more preferably at least 80% of its elongation in the cross machine direction.

Under used in the context of this application, the term "breathable" refers to a material that is permeable to water vapor and gases, but impermeable to liquid water. For example, breathable barrier materials" and "breathable film" ensuring the passage of water vapor through them, but they are virtually impervious to liquids, such as water. The indicator of "permeability" of any such material is determined on the basis of the rate of passage through it of water vapor (VWTR), and upper values of this index correspond to a material with a higher permeability to water vapor, and lower values correspond to less permeable to water vapor of the material. Usually breathable materials have the rate of passage through them of water vapor (WVTR) in the range of from about 500 to about 20,000 g/m2for 24 h (g/m2/24 h), in some embodiments, implementation of the olo from 1000 to 15,000 g/m 2/24 h, and in other embodiments from about 1500 to about 14,000 g/m2/24 hours

Used in the context of this application, the term "absorbent article" refers to any product, which is able to absorb water or other liquids. As an example, some absorbent products may serve as, but are not limited to, absorbent articles for personal hygiene, such as diapers, training pants, absorbent underpants, absorbent underwear, products for adults suffering from incontinence and personal hygiene products for women (e.g., sanitary napkins), swimwear, wet wipes for kids and so forth; medical absorbent articles, such as medical garments, surgical consumables (cut adhesive surgical tapes), absorbent pads, bandages, absorbent surgical sheets and medical wipes: food napkins: garments, and the like. Materials and methods suitable for such absorbent articles are well known to specialists in this field.

Under used in the context of this application, the term "hydrophobic substrate" refers to any shaped product, if it consists entirely or partially of a hydrophobic polymer, and the term "porous hydrophobic substrate" refers to any substrate if it is a small town in which to place a porous material and consists entirely or partially of a hydrophobic polymer. For example, a hydrophobic substrate can be a sheet material, such as a sheet of porous material. Hydrophobic substrate may also be a fibrous material, such as fibrous material of the fibrillated tape yarns, or a nonwoven fibrous fabric, or nonwoven fabric. These fibrous structures can be predominantly hydrophobic or can be selectively with the formation of clearly showing different hydrophobic zones. Non-woven materials include in its scope, but are not limited to, such as non-woven material obtained aerodynamic method from the melt, non-woven spunbond material mode of production, non-woven material formed of carding or material based on fiber canvas, formed by the aerodynamic method. As the hydrophobic substrate can also be used laminated construction, comprising two or more layers of sheet material. For example, the layers can be selected from the group consisting of nonwoven materials, obtained aerodynamic method from the melt, nonwoven spunbond production method. However, other sheet materials such as films or foams, can also be used in addition to or instead of the above non-woven material is impressive. In addition, the layers of the layered structure can be obtained from the same hydrophobic polymer or different hydrophobic polymers. The term "hydrophobic polymer" is used in this application to designate any polymer that is resistant to wetting or trudnosmyvaemye water, i.e. no affinity for water.

The term "hydrophobic polymer" is used here to designate any polymer that is resistant to wetting or which is not easily wetted, i.e. has a lower affinity towards water. Hydrophobic polymers include in its scope, but only as an illustration, polyolefins, such as polyethylene, polyisobutene, polyisoprene, poly-4-methylpentene-1, polypropylene, copolymers of ethylene and propylene, copolymers of ethylene, propylene and hexadiene, copolymers of ethylene and vinyl acetate: polystyrenes, such as polystyrene, poly-2-methylsterol, copolymers of styrene and Acrylonitrile having less than 20 mol.% Acrylonitrile, and copolymers of styrene with 2,2,3,3,-tetraferriphlogopite; halogenated hydrocarbon polymers, such as polychlorotrifluoroethylene, copolymers of chlorotrifluoroethylene with tetrafluoroethylene, polyesteramide, polytetrafluoroethylene, copolymers of tetrafluoroethylene with ethylene, polyterephthalate, polivinilhlorid and polyvinylidene fluoride; vinyl polymers, such as polyvinylbutyral, polyvinyldiene is, polyvinyltoluene, polivinilatsetatnoj, polyvinylsilane, polyvinylpyridine, polivinilacetat, polyphthalocyanine, polyptoton-isopropoxypropylamine and polymethacrylamide; acrylic polymers, such as poly-n-butyl acetate, politicalit, poly(-1-chloroformyl)tetrathiotetracene, poly(di-(chloroformyl)formatiert, poly-1,1-dehydroepiandrosterone, poly-1,1-dehydropolymerization acrylate, poly(1,1-dihydroperfluoroheptylacrylate), poly(heptafluoroisopropyl), poly[5-(heptafluoroisopropoxy)pentyl acrylate], poly[11-(heptafluoroisopropoxy)undecylenate], poly[2-(heptafluoropropoxy)acrylate], poly(nonattributable); methacrylic polymers, such as poly(bezelmaterial), poly(n-butylmethacrylate), poly(isobutyronitrile), poly(tert-butyl methacrylate), poly(tert-butylmethacrylate), poly(dodecylammonium), poly(ethyl methacrylate), poly(2-ethylhexylacrylate), poly(n-hexyllithium), poly(fenilsalicilat), poly(n-propylbetaine), poly(octadecylammonium), poly(1,1-dihydroartemisininpiperaquine), poly(heptafluoroisopropyl), poly(heptadecafluorooctyl), poly(1-hydrotherapeutic methacrylate), poly(1,1-dihydroergocornine), poly(1-hydroxyhexafluoroisopropyl), and poly-tretinoinretin-m is takelot: and polyesters, such as polyethylene terephthalate and polybutylene terephthalate.

Moreover, those skilled in the art it is obvious that the invention can be implemented in various modifications and variations of its implementation within the scope and essence of the invention disclosed in this application. So, for example, features of the invention are illustrated in the examples described in this application as one variant of implementation, can be used in another variant implementation, which leads to the following variant of its implementation. It should be understood that the present invention covers all such modifications and equivalents within beings and disclosed in the claims. Specialists in this field of technology, you should keep in mind that the present explanation of the nature of the invention is merely a description of illustrative examples of its implementation, and the invention is not limited to the described variants, and that the invention may be implemented in other ways.

Generally speaking, disclosed in this application is sabreena relates to non-woven cloth of synthetic fiber with printed. This non-woven fabric demonstrate the improved resistance to staining by oils when applying the ink composition on the visible outer surface of the nonwoven fabric. For example, the proposed ink composition demonstrates improved resistance to erase it from the surface of the outer layer of nonwoven fabric, even if it comes in contact with oily composition (for example, baby oil, lotion and so on). Generally speaking, the proposed composition of the ink is made in the form, which allows you to tighten their grip forces (for example, chemical and/or mechanical) with the surface of nonwoven fabric, even if it is a water-based ink. Essentially, the proposed composition of the ink may remain on the surface of the nonwoven fabric to which it is applied, protecting the appearance of non-woven fabrics and the overall aesthetic appearance.

For example, the non-woven fabric with printed may exhibit resistance coloring to the effects of oil more than about 3.8, for example, more than approximately 4,0 defined in accordance with the test method described in this application. In some embodiments of the invention, non-woven cloth with printed can demonstrate the durability of the paint to the impact of oil that is greater than about 4.1, for example, greater than about 4.2.

In one embodiment, the invention is ecata the surface of the nonwoven fabric may be a visible surface of the layered material. For example, the printed surface may be visible outer surface (for example, as the outer visible surface) of the laminate absorbent articles consisting of a nonwoven fiber fabric and film coating. Essentially, the proposed composition of the ink may be printed directly on the face outward layer of non-woven cloth, not on the underlying layer of the layered material with an outer covering (e.g., film). When using absorbent products excluded erasing the proposed composition of the ink with its outer coating and transfer them to the skin of the user or caregiver of a person, even if the outer coating is in direct contact with the oily composition. Thus, in accordance with the invention it becomes possible application of the ink composition on face outward nonwoven layer that enables them to reduce their consumption, compared with a seal carried on the inner film layer, simultaneously achieving the desired aesthetic appearance and the necessary firmness coloring to oils. In addition, the color intensity of the proposed composition of the ink printed on facing outward nonwoven layer of the product can be stored without interfering with exposure to the overlying layer.

A. non-Woven cloth

Under this and the finding, the proposed composition of the ink is applied (printed) onto the surface of nonwoven fabric of synthetic fibers. Synthetic fibers can usually be fibers of a hydrophobic polymer. In one particular embodiment, the fiber nonwovens are primarily hydrophobic synthetic fibers. For example, more than about 90% of the fibers of the nonwoven fabric can be hydrophobic synthetic fibers, for example, more than about 95%. In another embodiment of the invention, almost all fiber nonwoven fabric (i.e., more than about 98%, about 99% or about 100%) are hydrophobic synthetic fibers.

Nonwovens can be produced by any well-known in the art methods. From a practical point of view, however, nonwoven fabrics and fibers of which form a non-woven material, usually obtained by way of extrusion from the polymer melt and the subsequent bonding of the obtained filaments with the formation of non-woven material. The technology of extrusion from the melt includes, among others, such well-known technology, as the technology of production of non-woven material made of a polymer melt blown technology in the manufacture of nonwoven material made of a polymer melt spunbond method. Known, of course, other ways of gaining the nonwovens, which can also be used. Such methods include laying the cloth in the air, the wet method of sheet formation, the formation of carding, and the like. In some cases it may be desirable or even necessary to stabilize the non-woven material using known means, such as spot, thermal bonding, bonding by passing through a stream of hot air and hydraulic tangling of the canvas.

As indicated above, the non-woven fabric may include predominantly of synthetic fibers, particularly synthetic hydrophobic fibers, such as polyolefin fibers. In one specific embodiment of the invention, for forming non-woven cloth, you can use polypropylene fibers. Polypropylene fibers may have a thickness of thread from about 1.5 to 2, 5 denier, and the non-woven fabric may have a value of basis weight of about 17 g per 1 m2(0.5 oz per square yard). In addition, the nonwoven material may include two or other multicomponent fiber. Typical examples of nonwoven materials produced from multicomponent fibers described in U.S. patent 5382400, issued in the name of Pike, and others, in the patent application U.S. 2003/0118816, published under the title "High Loft Low Density Nonwoven Fabrics Of Crimped Filaments And Methods Of leaking Same", and in the patent bid, medium, small the USA 2003/0203162, published under the title "Methods For Making Nonwoven Materials On A Surface Having Surface Features And Nonwoven Materials Having Surface Features", which in its entirety is included in the scope of the present application by reference for all purposes of the present invention.

Two-component fibers having a structure of type sheath/core, where the shell is made of polyolefin such as polyethylene or polypropylene and the core is made of a complex of the polyester, such as polyethylene terephthalate or polybutylene terephthalate, may also be used for the production of carded nonwovens or nonwoven spunbond production method. The primary role of the polyester core is providing elasticity and, thus, maintain, or restore the bulk elasticity in application and after removal of the load. Preservation and bulk modulus plays a role in the separation of the shell from the absorbent structure. This separation was demonstrated effect on dry skin. The combination of the separation membrane having a flexible structure, along with the treatment proposed in the scope of the present invention, may provide a more effective coating material to hold liquid and to ensure the dryness of the shell.

Since the ink composition can have improved durability of the paint when applied to neck the Noah fabric, it eliminates the need for pre-treatment, accelerating its adhesion to the canvas. Essentially, the proposed composition of the ink may be applied directly to the surface of the hydrophobic non-woven cloth without applying any other layer or coating located between the surface of nonwoven fabric and ink. However, if desired, the nonwoven fabric can be applied to any used for pre-treatment composition before rolling on his offer ink composition to improve the adhesion of ink to the non-woven cloth. Typical compositions that are suitable for pre-treatment of non-woven fiber fabric, is described in published patent application U.S. 2004/0121675 in the name of Snowden and others, in published patent application U.S. 2006/0003150 in the name of Braverman and others, in published patent application U.S. 2006/0246263 on Yahiaoui, etc. that are included in the scope of the present application by reference.

As already noted, the non-woven fabric may be part of the multilayer material as the outer surface. When using non-woven cloth composed of a multilayer material it gives him great softness to the touch, similar to the textile fabric. For example, a laminate structure film-nonwoven fabric can be formed from non-woven cloth, lying with the above film layer. In one embodiment, for example, non-woven fabric is superimposed on the film by thermal lamination with the formation of the multilayer material structure of the film-nonwoven fabric. However, any suitable method may be used to obtain such a multilayer material. Suitable methods for the connection film layer with a layer of nonwoven fabric described in U.S. patent 5843057, 5855999, issued in the name of McCormack; U.S. patent 6002064, issued in the name Kobylivker and others; US patent 6037281, issued in the name of Mathis and others, and international PCT application WO 99/12734, which in its entirety is included in the scope of the present application for reference for all purposes of the invention.

The film layer of the multilayer coating material is typically formed from a material that is virtually impervious to liquid. For example, the layer film coating can be formed from a thin plastic film or other flexible material impervious to liquid. In one embodiment, the layer film coating formed from a thin plastic film, having a thickness from about 0.01 mm to about 0.05 mm, for Example, thinned by stretching a polypropylene film having a thickness of about 0.015 mm, can be layered by thermal lamination with a nonwoven.

In addition, the film layer may be formed of material is a, impermeable to liquids, but permeable to gas and water vapor (e.g., "breathable"). This allows the vapors to pass through the multilayer material, but at the same time prevents the passing of the liquid secretions of the body. The use of breathable laminates particularly preferably, when a laminate is used as the outer coating of absorbent products to allow steam to escape from the absorbent core, but prevents the passage of fluids through the outer coating. For example, the breathable film may be a porous or solid film.

The film can be obtained from polyolefin polymers such as linear low density polyethylene (LLDPE) or polypropylene. Examples of predominately linear polyolefin polymers include, but are not limited to, polymers derived from the following monomers: ethylene, propylene, 1-butene, 4-methylpentene, 1-hexene, 1-octene and higher olefins, as well as their copolymers and ternary copolymers. In addition, copolymers of ethylene and other olefins, including butene, 4-methylpentene, hexene, hapten, octene, the mission and the like, are examples of predominately linear polyolefin polymers.

If desired, the breathable film may also contain an elastomeric polymers, such as al is staminia polyesters, elastomeric polyurethanes, elastomeric polyamides, elastomeric polyolefins, elastomeric copolymers, and so forth. Examples of elastomeric copolymers include block copolymers having the General formula a-b-A' or a-b, where each of the symbols a and a' means end block-based thermoplastic polymer, which contains styrene residue, such as poly(vinilkin), and where represents the average block-based elastomeric polymer, such as a conjugated diene or a polymer-based lower alkene (e.g., polystyrene-polyethylenimine-polystyrene block copolymers). You can also use polymers comprising Quaternary ABAB block copolymer, such as described in U.S. patent 5332613, issued in the name of Taylor and others, which in its entirety is incorporated into the present application by reference for all purposes of this invention. An example of such a four-block copolymer is SEPSEP-block copolymer is a styrene-poly(ethylene propylene)-styrene-poly(ethylene propylene). Commercially available a-b-A' and a-b-a-b copolymers include a few different compositions produced by the company Kraton Polymers, Houston, Texas under the trade name KRATON®. Block copolymers trademark KRATON® presents several individual songs, some of which are listed in U.S. patents 4663220, 4323534, 4834738, 5093422 and 530459, which in its full extent included in this application for all purposes of this invention. Other commercially available styrene block copolymers include S-EP-s, or the elastomeric copolymer is a styrene-poly(ethylene-propylene)styrene supplied by the company Kuraray Company Ltd., Okayama, Japan, under the trade name SEPTON®.

Examples of elastomeric polyolefins include elastomeric polypropylene and polyethylene is low density, such as obtained by means of catalysis with a single center of polymerization on metal or "metallocene" catalysts. Such elastomeric polyolefins are commercially available material manufactured by ExxonMobil Chemical Co., Houston, Texas under the trade names ACHIEVE® (based on propylene), EXACT® (based on ethylene), and EXCEED® (based on ethylene). Elastomeric polyolefins are commercially available materials which are produced by DuPont Dow Elastomers, LLC (a joint venture between DuPont and Dow Chemical Co.) under the trade name ENGAGE ® (based on ethylene) and the AFFINITY® (based on ethylene). Examples of such polymers are also described in U.S. patent 5278272 and 5272236, issued in the name of Lai and others, which in its full extent included in this application for all purposes of this invention. Also suitable for use some elastomeric polypropylene, for example, those which are described in p. the tent USA 5539056, issued in the name of Yang and others, and the U.S. patent 5596052 name Resconi and others, which in its full extent included in this application for all purposes of this invention.

If desired, mixtures of two or more polymers can also be used for forming a breathable film. For example, the film may be formed from a mixture consisting of elastomer with improved technological performance and elastomer with low technological performance. Elastomer with improved technological performance is typically an elastomeric material having a low potential of hysteresis, for example, less than about 75%, and in some embodiments, less than about 60%. Similarly, the elastomer with low technological performance is typically an elastomeric material having high potential hysteresis, for example, more than about 75%. The hysteresis can be determined by stretching at the beginning of the sample elastomer material relative to ultimate elongation of 50%, and then the sample is left to he could shrink to a size where the resistance value is equal to zero. As an example, particularly suitable for use hi-tech elastomers can serve as styrene block copolymers, such as those described above, and commercially available elastomeric materials, roizvedeniya by the company Kraton Polymers, Houston, Texas under the trade name KRATON®. Similarly, examples of particularly suitable elastomers with reduced technological indicators include in its scope elastomeric polyolefins, such as polyolefins obtained by the technology of metallocene catalysis (for example, metallocene-catalyzed linear low density polyethylene with a single center of polymerizatio), which supplies the market with company DuPont Dow Elastomers LLC under the trade name AFFINITY®. In some embodiments, the elastomer with improved technological performance can constitute from about 25 wt.% to about 90 wt.% from the polymer component of the film and the elastomer with low technological indicators may likewise constitute from about 10 wt.% to about 75 wt.% from the polymer component of the film. In addition, examples of such elastomeric mixture consisting of a high-tech and low-tech elastomers described in U.S. patent 6794024, issued in the name of Walton and others, which in its full extent incorporated in this application by reference for all purposes of this invention.

As already noted, the breathable film can be made microporous. Micropores form channels, which are often referred to as the winding paths from one surface of the film to the other. The liquid in contact with one side of the film, has no direct prog is Yes her through the film. On the contrary, the network of canals in the microporous film prevents the passage of liquids but allows the passage through it of gases and water vapor. The microporous film can be obtained from a mixture of film-forming polymers and fillers (e.g. calcium carbonate). The filler is a material in the form of particles or other form of material which can be introduced into the film-forming mixture for extrusion of the film and which do not interact chemically with extruded film, but which is capable of evenly dispergirujutsja across the film surface. Usually, based on the calculation of dry matter relative to the total mass of the film, laminated film contains from about 30 wt.% to about 90 wt.% the polymer. In some embodiments, the film comprises from about 30 wt.% to about 90 wt.% the filler. Examples of such films are shown in U.S. patents 5843057 and 5855999, issued in the name on McCormack; U.S. patent 5932497, issued in the name of Morman and others; US patent 5997981, issued in the name of McCormack and others: U.S. patent 6002064, issued in the name Kobylivker and other: U.S. patent 6015764, issued in the name of McCormack and others: U.S. patent 6037281, issued in the name of Mathis and others; US patent 6111163, issued in the name of McCormack and others; and U.S. patent 6461457, issued in the name of Taylor and others, which in its full extent included in this application by reference for all purposes of this invention.

Films usually get the breathable formed by stretching films with the placeholder with the formation of a microporous structure, with the aisles because during stretching of the polymer film is separated from the filler (e.g. calcium carbonate). For example, the breathable material contains thinned by stretching the film (stretch film), which includes at least two basic components, i.e. the polyolefin polymer and the filler. These components are mixed, the resulting mixture is melted and then ekstragiruyut inside film layer using one of a wide variety of technologies for films, well-known experts in the field of production of film materials. Such methods of production of films include, for example, methods of forming films of flat-slotted extrusion blow film.

Another type of breathable film is a monolithic polymer film, which is non-porous, solid film, and which due to its molecular structure can serve as impermeable to liquid and permeable barrier layer. Among components of different polymer films that fall under this type of films, you can specify the films made from polymers containing a sufficient amount of polyvinyl alcohol, polyvinyl acetate, ethylene vinyl alcohol, polyurethane, ethylene-methyl-acrylate, ethylene-methyl acrylic acid, in order to make them breathable. Have not had the intention to focus on a particular mechanism of action, I believe that films prepared from such polymers, solubilizing water molecules and facilitate their transfer from one film surface to another. Accordingly, these films can be quite continuous, i.e. non-porous, due to which they are virtually impervious to liquid, but at the same time permeable to water vapor. Breathable films, such as described above may form the entire surface of the breathable material or they can be part of a multilayer film. Multilayer films can be obtained by coextruding polymer layers as by extrusion technique with inflation, and by extruding flat film, coating, extrusion, or any traditional method of laminating. In addition, other breathable film materials that may be suitable for use in the present invention are described in U.S. patent 4341216, issued in the name Obenour; U.S. patent 4758239, issued in the name of Yeo and others; US patent 5628737, issued in the name Dobrin and others; US patent 5836932, issued in the name Buell; U.S. patent 6114024, issued in the name Forte; U.S. patent 6153209, issued in the name of Vega and others; US patent 6198018, issued in the name of Curro; U.S. patent 6203810, issued in the name of Alemany and others; and the U.S. patent 6245401, issued in the name of Ying and others, which in its full extent incorporated in this application by reference for all purposes of this invention.

In one embodiment, the invention is a multilayer material consists of two layers: non-woven cloth and film. On the other hand, in some embodiments, implementation of the multilayer material may include additional layers, in the case when the non-woven fabric forms the outer surface of the multilayer material for making ink composition. In this case, as an additional layer(s) laminated material may be a nonwoven fabric, film, foam and the like.

In one specific embodiment, the non-woven fabric suitable for use as the bottom sheet in the multi-layer structure (that is, the outer coating) absorbent products. The lower absorbent sheet products is normally impermeable to the liquid layer, which can also be breathable. For example, in a particular embodiment, the bottom layer is a multilayer material impervious to the liquid film attached to the nonwoven fabric of polyolefin fibers.

Exemplary multi-layer material containing the non-woven fabric with printed, used in the construction of the training pants, shown in figures 1 and 2. Figure 1 is a perspective view of a typical sample of the training pants 10, and Figure 2 - exploded view poper is knogo slice Figure 1 along the line 2-2. It is the outer visible surface 18 of nonwoven fabric 14 constitutes or forms the outermost visible surface of the training pants 10, on which the print image 16. Shown in these figures is a typical sample of nonwoven fabric 14 is coated with a printing image is used as the outer face layer of the bottom sheet 12 training pants 10, but which may be included in various types of absorbent articles, which may be desirable to print the printing information or the printed image, including its volume, but not limited to, diapers, personal hygiene products for women, products used in case of incontinence in adults, training pants, swim trunks, and so on.

For example, figures 1 and 2, the training pants 10 contain the lower sheet 12, which may be in the form of a two-layer laminate (laminate)comprising nonwoven fibrous fabric polyolefin 14 connected properly with impermeable for liquid film 22. Canvas 14 has opposite surfaces such as the inner surface 20 and outer visible surface 18. The film 22 has opposite surfaces, such as surface 24 facing surface of the inner layer 20 of the blade 14, and the surface 26 facing the compo is itemu absorbent element 26.

One way to make these products more attractive provides for imprinting on them vivid color images. Any desired pattern or other image can be applied or printed on the outer visible surface 18 defined by a nonwoven, when using the ink composition disclosed in the present application. For example, a number of intricate patented images can be printed on the outer visible surface 18 of the rear sheet 12. Under the outer "visible" surface refers to the surface that is visible, in the case when the product has areas that remain uncovered (for example, uncoated outer surface of absorbent products). As already mentioned, the introduction of cross-linking agent in the ink composition may slow erasing the image from the surface of the product during its use. This, essentially, allows to improve the resistance to fading printed on the outer covering of absorbent products of the images, and also prevents staining any surface (e.g. skin), which is in contact with the outer surface of such products.

Permeable to liquid top layer 30 and the layer from the side of the body) is located on the side of the absorbent core 28, the opposite lower impermeable layer 12, and he before the hat is layer, adjacent to the skin of the user. Permeable to liquid top layer 30 is usually used to facilitate isolation of the skin of the user from the liquid discharge held in the absorbent core 28. For example, permeable to liquid top layer 30 is a surface directed to the body, which is usually pliable and soft to the touch and does not irritate the skin of the user. Usually the top layer 30, in addition, is less hydrophilic than the absorbent core 28, which its surface adjacent to the skin of the user remains relatively dry. Permeable to liquid top layer 30 makes it easy to pass fluid throughout its thickness.

Permeable to liquid top layer 30 may be made of various materials, such as cellular plastics, reticulated foam, perforated plastic films, natural fibers (such as cellulose or cotton fibers), synthetic fibers (for example, fiber-based polyesters or polypropylene fibers), or combinations thereof. In some embodiments, the implementation to obtain permeable to the liquid of the upper layer 30 are woven and/or nonwoven materials. For example, permeable to liquid top layer 30 may be formed from a cloth polyolefin fibres obtained and the dynamic method from the melt or spunbond method. Permeable to liquid top layer 30 may be a bonded carded webs of natural and/or synthetic fibers. Permeable to liquid top layer 30, can also consist of mainly hydrophobic material, which optionally treated with a surfactant or otherwise to give it the desired level of wettability and hydrophilicity. The surfactant can be applied by any conventional methods such as spraying, printing, coating using a brush device, coating with a brush, applying intumescent coatings and the like. In the case of PAHs, it can be applied to the entire surface permeable to the liquid of the upper layer 30, or can be selectively applied to specific areas permeable to the liquid of the upper layer 30, such as the medial section along the median line of the diaper. Permeable to liquid top layer 30 can also be included as a component of the composition, which is made with possibility of transfer to the skin of the user to improve the condition of skin. Suitable compositions for use on the surface is permeable to the liquid of the upper layer 30 is described in U.S. patent 6149934, issued in the name Krzysik and others, which in all its full of the ones included in the scope of the present application by reference for all purposes of the present invention.

Absorbent core 28 may be manufactured from various materials, but typically includes a matrix of hydrophilic fibers. In one embodiment, as an absorbent cloth used is one that contains a matrix of crushed wood fibers. One type of such "fluff" material that can be used in the scope of the present invention, known under the trade name CR1654, which supplies the US market for the firm Alliance of Childersburg, Alabama, and he is a bleached, vysokobarnogo sulfate wood pulp containing primarily fiber, containing mainly fiber softwood. In addition, in accordance with the invention can also use cloth produced aerodynamic method of forming fabric. In accordance with an aerodynamic way the cloth is formed of bundles of short fibers generally have a length of about 3 to about 19 mm, which divide the air stream and under the action of the air stream is transported and placed on the mesh conveyor, typically using a vacuum feed system. Randomly laid fibers are then fastened to each other using, for example, hot air or glue applied by spray. Another type of absorbent non-woven cloth, suitable for receiving the absorbent core 28, before the hat is material joint molding, which can be obtained from a mixture of cellulose fibers and fibers blown from the melt.

In some embodiments, the absorbent core 28 may include superficiali material, such as swelling in water material which can absorb at least about 20 times its weight, and in some cases at least about 30 times its weight of an aqueous solution containing 0.9 wt.% sodium chloride. As an example superficialy materials you can specify natural, synthetic and modified natural polymers and materials. In addition, as superficialy materials can be inorganic materials such as silica gels, or organic compounds such as crosslinked polymers. As an example, synthetic superficialy polymeric materials can serve as alkali metal salts and ammonium salts of polyacrylic acid and polymethacrylic acid, polyacrylamide, polyvinyl simple esters, copolymers of maleic anhydride with vinyl ethers and alpha-olefins, polyvinylpyrrolidone, polivinilpirrolidon, polyvinyl alcohol and their mixtures and copolymers. Other superficiale materials include natural and modified natural polymers, such as hydrolyzed grafted Acrylonitrile starch grafted acrylic acid starch, ethylcellulose, chitosan, carboxymethylcellulose, hydroxypropylcellulose, natural gums, such as alginates, xanthan gum, carob bean gum and the like. In accordance with the present invention it is also possible to use a mixture of natural and completely or partially synthetic superficialy polymers. Other suitable absorbent gelling materials are disclosed in U.S. patent 3901236, issued in the name Assarsson and others, in U.S. patent 4076663 issued by Matsuda and others, and in U.S. patent 4286082 issued by Tsubaki and others, which in its entirety is included in the scope of the present application by reference for all purposes of the present invention.

Although not covered specifically, absorbent articles such as training pants, shown in figure 1, may also include other layers not shown in the drawings. For example, additional absorbent (holding) layer may be included in the design of such products in order to slow down the speed and penetration of growth or rapid discharge of the liquid, which can quickly enter and accumulate in the absorbent core 28. Preferably, an additional absorbent layer can rapidly accept and temporarily store the liquid before it enters the region of accumulation or to retain part of the portions coming into the absorbent core 28. the ri included in the design of this product such absorbent layer, it is usually located between the permeable for liquid top layer and the absorbent core. In an alternative embodiment, the absorbent layer can be located on the surface directed outwards to the permeable for the liquid of the upper layer. Specified absorbing layer is usually produced from vysokolegirovannyh materials. Suitable materials for the production of such a layer can include a porous woven materials, porous non-woven material and the perforated film. Some examples include, but are not limiting of the scope of the invention, a flexible porous sheet material of polyolefin fibers such as polypropylene, polyethylene or polyester fibers: spunbond nonwoven fabric from polipropilenovyy, polyethylene or polyester fibers; non-woven sheets of cellulose fibers bonded non-woven cloths made of synthetic or natural fibers or combinations thereof. Other examples of suitable materials for the absorbent (holding) layer is described in U.S. patent 5486166 and 5490846, issued in the name of Ellis and others, which in its entirety is included in the scope of the present application by reference for all purposes of the present invention.

In addition to the above components, the absorbent articles may also contain various other components known in the art. Example is, absorbent article may also include wrapping a layer of hydrophilic thin light fabric (not shown in figure 1), which allows you to maintain the integrity of the fibrous structure of the absorbent core, formed by the aerodynamic method of molding. This tissue layer is usually around the absorbent core, at least two main front surfaces and consist of an absorbent cellulosic material, such as a gasket of creped cellulose wadding or a high-strength wet cloth. The specified wrapping a layer of light thin fabric can be made in the form, which includes the presence of a layer with wicking effect which contributes to the rapid distribution of the liquid throughout the mass of absorbent fibers of the absorbent core. Wrapping material located on one side of the absorbent fibrous mass may be attached to the wrapping material located on the opposite side of the fibrous mass to ensure the effective packing of the absorbent core.

C. the ink Composition

In accordance with the present invention, the ink with which the may contain in its composition of a crosslinking agent in the amount sufficient for binding of the molecules of its components in a single system. As a result, the ink becomes more in the bond immediately after applying them to the substrate. For example, after applying the proposed composition of the ink to the substrate, they can instantly coupled with the surface of the substrate to form a 3-dimensional chemical structure. 3-dimensional structure of the proposed composition of the ink may prevent abrasion from the substrate by mechanical influences. For example, when applying the proposed composition of the ink on the non-woven fabric can be formed of a mesh structure, which coats the fibers of the nonwoven fabric, thereby preventing abrasion of the fibers with a thickened cross-linking agent ink.

In addition, a crosslinking agent can bind the molecules of ink themselves with the relevant sections on the substrate. Thus, the proposed composition of the ink may chemically to contact the substrate and prevent its Erasure from the fibers by chemical influences. For example, when applied to the nonwoven fabric, the ink molecules can be contacted with the polymers of the fibers of the nonwoven fabric.

In addition, the authors of the present invention have found that the introduction of the proposed composition of the ink of a relatively large amount of cross-linking agent dramatically increases the resistance to stir the of ink, under the action of fat deposited on such basis. For example, a crosslinking agent may be present in the ink composition in amounts of more than 2 wt.% in terms of dry weight of the ink composition, in particular more than 4 wt.%. In some embodiments, a crosslinking agent may be present in an amount of about 5 wt.% to about 20 wt.%, in particular, from about 7 wt.% to about 15 wt.%. For example, in a particular embodiment, the crosslinking agent may comprise from about 10 wt.% to about 12 wt.% in the proposed composition of the ink. It should be noted that after applying the proposed ink on layered material, they at drying usually contain a large % crosslinking agent, calculated on the dry weight due to evaporation of the solvent, as is more fully discussed below. Since the ink composition are usually to provide them quick drying after application on such a substrate, crosslinking agent has a short time to link all components of the resulting ink composition. In line with this, the amount of crosslinking agent used for crosslinking of the compositions of other types may not provide adequately linking all the components in the ink composition, which significantly affects the index of stability of ink to the effects of fat after applying them to the substrate. Not the same the friends to be bound by theory, the authors of the present invention believe that the relatively high content of crosslinking agent in the proposed composition of the ink may increase the degree of crosslinking, which occurs immediately after application of the ink of the present invention on a substrate. Suppose that the rate of crosslinking increases only within such a short period of time after application of the ink to the substrate, and not to complete their drying on the substrate, and thus, ink can be sufficiently crosslinked as a substrate, and to link their components.

A crosslinking agent can be selected from such agents, which are able to sew the components of the ink so as to form a 3-dimensional chemical structure. In addition, a crosslinking agent may facilitate the binding of the printed ink composition with the fibers of the nonwoven fabric. In some embodiments of the invention, a crosslinking agent capable of crosslinking at room temperature or slightly above it, which eliminates heating of the non-woven cloth above its melting point during vulcanization. In another private embodiment, use of a crosslinking agent, which becomes reactive at pH that is neutral or acidic, which allows to maintain the ink at a pH>8 while mixing and applying them to the substrate. Song DL is podocarpaceae support at pH> 8 using the solution of the volatile alkali such as ammonia alkali. Volatile alkali remain in the solution until, until evaporated during drying at room temperature, or alternatively by heating a small amount in order to accelerate the evaporation. In any case, the curing temperature may be at a temperature below the melting temperature of the canvas. Loss of alkali leads to a decrease in the pH of the composition, which results in starting the action of a crosslinking agent. Examples of suitable cross-linking agents that can be used in accordance with the present invention include, but are not limited to, HAM-2, HAM-7 and CX-100, supplied to the market a Noveon, Inc. of Cleveland, Ohio. These crosslinking materials are aziridine oligomers with at least two aziridine functional groups.

In addition, other amplifiers clutch can be added in the proposed composition of the ink. For example, Carboset N supplied to the market firm a Noveon, Inc. of Cleveland, Ohio, is an acrylic polymer colloidal dispersion in an aqueous ammonia solution, which dries to form a transparent, water-resistant, not adhesive thermoplastic film. In addition to the crosslinking agent, the ink composition generally contains a dye (e.g., pigment or dye), dissolve the ü and any other required ingredients. Usually, the pigment refers to the dye on the basis of inorganic and organic particles that do not dissolve in water or solvents. Typically, the pigments form an emulsion or suspension in water. On the other hand, the dye belongs mostly to the dye, which is soluble in water or solvents.

The pigment or dye may be present in the ink composition of the present invention in amounts effective to provide a visible imprint after applying ink to the substrate. For example, the pigment or dye may be present in the ink composition of the present invention in a concentration of from 0.25% to about 40% (based on dry weight, and preferably in a concentration in the range of greater than or about equal to 1% and less than or about equal to 10%.

Examples of inorganic pigments include titanium dioxide (for example, white pigment 6 Cl No. 77891), carbon black (for example, black pigment 7 Cl No. 77266), iron oxides (for example, red, yellow and brown micaceous iron pigment), black micaceous iron pigment (for example, black pigment 11 Cl No. 77499), chromium oxide (e.g., green chromakey pigment), ferric ammonium ferrocyanide (blue), and the like.

Examples of suitable dyes that can be used in accordance with the present invention as an additive include, for example, acid dyes and sulfonated dyes, including direct dyes. Examples of other usable dyes include azo dyes (e.g., solvent yellow 14, disperse yellow 23 and metamelomai yellow), antrahinonovye dyes (for example, solvent red 111, disperse violet 1, solvent blue 56, solvent orange 3), xanthene dyes (e.g., solvent green 4, acid red 52, basic red 1, and solvent orange 63), osinovie dyes (for example, a black colorant for ink-jet printing and the like.

Inks are usually obtained in the form of a dispersion or solution in low-viscosity media. As rest is ritala can be used aliphatic hydrocarbons in the mixture with the conventional binder, such as polyamide, shellac resin, nitrocellulose resin and a copolymer of styrene-maleic acid. Typically the ink-based solvents include non-catalytic polyurethane block copolymer, which usually demonstrates superior durability compared to traditional binder used in the ink composition for flexographic printing, such as solutions containing a styrene-maleic acid, rosin-maleic resin and acrylic resin. Examples of suitable mixtures of solvents include various acetates, such as ethyl acetate, N-propyl, isopropylacetate, isobutyl acetate, N-butyl acetate, and mixtures thereof; various alcohols, including ethanol, isopropyl alcohol, n-propyl alcohol, and mixtures thereof: and also ethers, glycol, including Ektasolve® EP (monopropylene ether of ethylene glycol), EB (monobutyl ether of ethylene glycol), DM (onomatology ether of diethylene glycol), DP (monopropylene ether of diethylene glycol) and RM (onomatology ether of propylene glycol), which can be obtained from the company Eastman Chemical of Kingsport, Tennessee. As examples of other glycols suitable for use in accordance with the present invention, it is possible to specify DOWANOL®supplied to the market by the company Dow Chemical, Midland, Michigan. Suitable for use with solvent mixture m which may be a mixture, containing from about 50 to about 75% of the common ether glycol, from about 25 to about 35% N-propyl acetate, and from about 15 to about 25% n-butyl acetate.

Examples of usable water-based inks include emulsions, which can be stabilized in aqueous ammonia solution, and they can optionally contain alcohols, glycols or ethers, glycol as cosolvent. Usually organic solvents (about or less than 7%) in the calculation of the total composition of water-based inks, for example, alcohols, in particular propane-2-ol, can be added to the ink in order to accelerate curing and facilitate wetting, glycols, for example, monopropellant to slow curing, ethers, glycol, for example, Dobropillya onomatology ether to facilitate the education of the film. These solvents can be chemical packaged products that supply on the market of different companies. Typically, the compositions water-based inks include smeshivaemost emulsion acrylic copolymers, which can exhibit excellent durability compared to traditional neobratimii cross-link polymeric binder such as aqueous dispersions of acrylic polymers and copolymers. In addition to the solvents and pigments in the ink composition may contain any binder re the Gent or its mixture. This binding promotes fixation of pigment on the surface of cover layer 12. In General, the ratio of pigment to binder is usually from 1:20 to 1:2.

Waxes can also be logged in the ink composition to increase slip and improve the abrasion resistance of the ink from the printed polyolefin substrate. In the common classification of waxes include animal waxes (such as beeswax and lanolin), vegetable waxes (e.g. Carnauba and kandellilsky), mineral waxes (such as paraffin wax and microcrystalline wax), synthetic waxes (such as polyethylene wax, polietilenglikolya wax, wax teleonomy ®). In one embodiment, the wax may be present in an amount of about 0.5% to about 5% based on the entire formulation of ink when they are wet.

In one embodiment, the ink composition used in the method according to the invention with the formation of the logo, is a composition of the ink, designed for a specific type of printing. And of course the selected ink must be safe for humans and should not have a harmful effect on the environment. In addition, it is desirable that the composition of the ink can be used for printing for a specific purpose and, preferably, that it was Usto the Chiva to temperature conditions of the technological process, used to obtain the absorbent products of the present invention, for example, the temperature used in the process of vacuum deposition of perforations on the film and similar methods where the use of elevated temperature.

C. printing Methods

The specific method of applying the proposed composition of the ink on the surface of the nonwoven fabric may be any suitable printing method, which includes flexographic printing, gravure printing, offset printing, ink jet printing and the like. The proposed method can be used to print any design, picture or other image on the surface of the nonwoven cloth.

It is well known to specialists in the art that for each printing method should usually be a specific ink composition used only for the specific printing method. Specific ink formulations are usually as a specific printing process depending on printing methods and printing substrates. For example, the ink composition for inkjet printing is significantly different from the ink composition for flexographic printing partly due to the use of these two methods of printing various types of printing systems.

For example, inks for flexographic printing is not limited icehouse type of ink and their composition can be used dyes and/or pigments, and even such pigments, which contain a relatively large particle size. However, the ink for inkjet printing, typically limited to ink formulations that do not contain particles, or, at least, such ink with a relatively small particle size. In fact, the ink for ink-jet printing typically contain dyes in contrast to pigments, which are used as coloring substance in the specified ink composition.

1. The ink composition for flexographic printing

In one specific embodiment, the ink composition can be applied to the nonwoven fabric by way of flexography, which allows us to provide the right balance between economic efficiency, high speed and high quality printing, and is particularly suitable for printing on any non-woven cloth. In General, flexography is a printing technology, which uses flexible printing form with a printing elements that extend over whitespace, or photopolymer plates to transfer images to polymer film. Flexible printing forms usually carry low viscosity ink directly on the polymer film. In the flexographic printing technology can be used as water-based inks and water-based ink. And because the systems flexographic the print can be used with water-dilutable ink or water-based ink, which are less expensive than ink oil-based, and the cost of printing is usually lower than other types of printing.

Flexographic inks are typically low viscosity ink, which has a composition similar to the ink used in gravure printing, but different from those used in lithography. Low viscosity ensures faster drying and, as a result, speeds up the printing process, which in turn allows you to lower the production process. Viscosity flexographic inks can vary at room temperature (e.g. about 20°C.) in the range of from about 300 centipoise (CP) to about 500 CPS. To determine the rate of viscosity usually use well-known in this field, methods, and you can use the viscometer to obtain accurate values of viscosity. For example, you can use a standardized method of measuring viscosity according to ASTM D445. Flexographic inks usually contain about 50% solids when they are in hydrated form, and an introduction to the wetted ink composition 2 wt.% cross-linking agent leads to the fact that the ink is dry contain about 3.5 wt.% to about 4 wt.% a crosslinking agent, calculated on the dry weight of the composition. Thus, in the dry the ink composition, the content of the crosslinking AG the NTA can reach more than 3.5 wt.% calculated on the dry weight of the entire composition, in particular, more than 7.5 wt.%, when ink is applied to the nonwoven fabric by flexography. In some embodiments, the dry ink composition may contain a crosslinking agent in an amount of about 10 wt.% up to 30 wt.%, in particular from about 15 wt.% up to 25 wt.% when applied to the nonwoven fabric by flexography.

The authors of the present invention found that flexo water-based ink containing in its composition of a crosslinking agent, can improve their resistance to abrasion under the influence of fat, compared with the composition of the flexographic ink, solvent-based. Thus, the method of flexographic printing water-based inks can provide additional advantages over other printing technologies.

Composition flexographic water-based inks typically includes a pigment or dye, a polymer resin, a binder or wax, an organic solvent and water. Of course, such ink compositions can vary depending on the characteristics of the original materials, the desired print quality, including various characteristics of materials supplied by numerous manufacturers.

2. The ink composition for inkjet printing (e.g., digital press)

The ink composition for inkjet printing typically has a relatively low wescast is, allowing you to apply the ink to the substrate by spraying or nabryzgivaniya ink through the inkjet print head. The viscosity of the ink for inkjet printing can vary in the range of from about 0 SP 50 SP, in particular from about JV 0 to 30 JV at room temperature (e.g. about 20°C). Ink for inkjet printing can be further divided into compositions for continuous ink supply system, having a viscosity of about from 0 SP 5 SP, and compositions for ink-on-demand, having a viscosity of about from 0 to 30 SP. Ink for inkjet printing typically contain from about 2% to 5% solids when they are in hydrated form, and an introduction to the wetted ink composition 2 wt.% cross-linking agent leads to the fact that the ink is dry contain from about 25 wt.% to about 50 wt.% a crosslinking agent, calculated on the dry weight of the composition. Thus, in the dry the ink composition, the content of the crosslinking agent can be more than 25 wt.% calculated on the dry weight of the entire composition, in particular more than 50 wt.%, when ink is applied by ink jet printing on non-woven material. In some embodiments, the dry ink composition may contain a crosslinking agent in an amount of about 40 wt.% up to 80 wt.%, in particular, from about 50 wt.% up to 70 wt.%, when ink is applied to the nonwoven fabric inkjet printing.

In some cases, the introduction of t is whom a relatively large amount of cross-linking agent may increase the viscosity of the ink composition, especially, if there is any premature crosslinking before applying the ink composition of the present invention the nonwoven fabric, which can significantly degrade the quality of inkjet printing. However, the authors of the present invention have found that the introduction of additives to enhance the adhesion, in the ink composition of the present invention can reduce the amount of crosslinking agent used in the ink, as without a significant increase in their viscosity, and without significant influence on the resistance erase ink when they dry.

As already noted, as an additive to enhance the adhesion, can be used Carboset 514H supplied to the market firm a Noveon, Inc. of Cleveland, Ohio, which is an acrylic polymer colloidal dispersion in an aqueous ammonia solution, which dries to form a transparent, water-resistant, not adhesive thermoplastic film. For example, acrylic polymer colloidal dispersion can be introduced into the liquid ink composition in an amount of about 15 wt.%, in particular, from about 1 wt.% up to about 10 wt.%, based on the ink composition in the liquid state.

Alternatively, the ink is dry can contain acrylic polymer in the form of a colloidal dispersion of about 80 wt.%, in particular, from about 5 wt.% up to 75 wt.%. For example, the ink in a dry type may contain acrylic polymer in the form of a colloidal dispersion of from about 10 wt.% up to 50 wt.%.

Test method

Used test method abrasion resistance to determine whether the combination of the treated non-woven sheets and ink have sufficient resistance to abrasion. Test method abrasion resistance was based on the standard 116-1983 testing according to the methods of the American Association of specialists in dyes for fabrics (AATS). Test method are included in full in this application, but with a few modifications described in the International application WO 2004061200 A1. In the method of testing according to the standard AATS use a device called a device with a rotating vertical unit for determining the stability of erasing, in which a piece of the test material tinder about exemplary material. In a modified test method abrasion resistance used the device Sutherland Rub Ink Tester (series Sutherland 2000 Rubtester)supplied by the company Danilee Company of San Antonio, Texas, as an alternative to the standard device for determining the resistance to abrasion. The device Sutherland Rub Ink Tester is used in the printing industry to assess persistence erase ink and coatings applied on the printed substrate. This device has a wider area of the test than the standard device for determining the resistance to abrasion. The measuring head is 2×4 inch square test is about sample 8 inch 2. The measuring head is moved horizontally over the test sample along the curved trajectory. Also includes various cargoes to load changes on the surface of the test specimen, and the number of elements of the head movement is a variable value. In this test method used weight 4.0 lb and 50 brushing movements at a frequency of 42 cycles per minute. The test sample of tissue can be used up about any material that can be easily attached to the opposite surface of the device. In accordance with the methodology EATS any transfer of ink from the test sample determined from the point of view of quality system evaluation from 1 to 5 on the standard gray scale, where 5 means no transfer of ink from the test sample, and 1 means the critical transition rate ink. The main difference between the test method used in the following examples, and methods AATS was quantitative method for assigning values of color stability. This used spectrodensitometer for assigning measurement values to the total transfer of the dye. This measured value is known as the "Delta E". Then put the equation to convert the value of Delta E is situated in the range from 1 to 5, which is equivalent to the scale of the evaluation of color stability by the method EATS.

In accordance with the test procedure, the samples were analyzed on a CIELAB color contrast, which is expressed as F (feeling). E then transformed into numerical score ranging from 1 to 5 according to the following formula: CR=Exp. (-B), where A=5,063244 and=0,059532 (E), if E is less than 12, or A=4,0561216 and=0,041218 (E), if E is greater than 12. This metric CR is an assessment of the strength of color. A rating of 1 corresponds to a low or poor durability (maximum color change), while a rating of 5 corresponds to the high resistance (minimal color change), and this value usually indicates the absence of transfer of the ink from the test sample to the sample material.

Using spectrodensitometer allowed us to assess more objectively the results obtained due to less dependence on the operator and allowed us to achieve high precision measurement and quality control throughout the entire printing process. Spectrodensitometer model X-Rite 938 manufactured by the company X-Rite, Inc., Grandville, Michigan.

Obtaining samples

As samples for testing used a layered material containing non-woven fabric of polypropylene spunbond fibers production method, and a film material having a basis weight of about 1 oz/yd2. The samples were cut with a precision of up to 2.5 inches wide and 7.0 inches in length, unless otherwise noted, with the testing center area at a right angle.

The testing methods

1. Cut out a sample size of about 2.5 cm wide and 7.0 cm in length in the machine direction of the substrate, unless otherwise specified in special instructions.

2. Mark undyed cotton lane 2×6 inches with the individual information of the sample.

3. Put undyed cotton strip over the entire length parallel to the NAP is to t the sample surface, subjected to friction. Attach the sample to the base of the test installation so that the surface with the imprint of the face was pointing up, and the area of the test center.

4. Weigh one piece of tissue for testing color fastness to wet rubbing. Thoroughly impregnated with the tested fabric baby oil to bring the level up to 65% ±5% and calculate the % moisture according to the formula: % moisture = wet Weight of tissue - Weight dry cloth divided by Weight of dry cloth ×100). (When determining color fastness to dry rubbing this stage can be eliminated. When determining color fastness to wet rubbing water substitute baby oil.)

5. Paste test unpainted fabric to the cargo weight 4.0 lbs, placing the test sample (with adjustment of the long side to long side) of the cargo and stick with sticky tape 610 to provide additional adhesion. Make sure that the sample is firmly stuck together and that the sealed side of the material directed upward, when put on load of sticky tape.
