BRIEF DESCRIPTION OF THE INVENTION

The present invention aims to create a composite material consisting of non-woven cloth and film and has properties that would make it particularly suitable for use as loopy component fasteners, and which would be a layered material of the film layer and the layer of nonwoven material with a pre-established relationships, in which the links of the layered material is separated and independent from the relations of non-woven material with a pre-made ties, with strands and fibers between such places relations layered material can be both related and unrelated. For superior comfort and create opportunities to use as fastening components the ial group can be performed so what he was going to pass air at a transmission rate of water vapor above about 100 g/m2/24 hours and can have a value of hidronor at least 50 mbar (5 kPa). When used with a component of complementary hooks loopy clasp formed from this composite material provides the ability to lock in any position of the fastening element on the product, provided the corresponding possibility of re-engaging after a certain period of time and a certain number of cycles continents liners and fastening, suitable for many use cases as a product of single use products or restriction. The layer of nonwoven material contains a pattern of relations, which is a uniform or nonuniform drawings, the education which is obtained from the surface area without wires constituting at least 70% of the area of any square of side 100 cm of the surface of the nonwoven material. In addition, the frequency location of connections allows to obtain the density of the pattern lying in the range from about 50 to about 200 links per inch2(7,8-31 links/cm2), while ecstasy or a multilayer structure, or press together the structure with an open layer of soft amorphous polymer, or monoclinal structure, and in any case, essentially a microporous barrier to liquids and which is comfortable to wear and compatible with non-woven material. The creation of the layered structure can be accomplished by application of heat and/or pressure, with the use of the properties of amorphous polymer or in a multilayer film, or in a separate overlay binder layer, for example, in the variant embodiment with the monolayer film. Selected independent pattern ties layered material so that the area between the bonds laminates contain a separate communication nonwoven material, which additionally collect fibers or strands on the surface of the nonwoven material. For example, the patterns of relations of the layered material can cover less than 50% of the surface area of the layered material, preferably less than about 30%, can form a uniform or non-uniform shape, and/or can be configured in the General case, so that the number of these relations will be significantly fewer than the number of pre-established relationships of non-woven material. DL the elements when used as a loopy component elongated layered material can be formed by stretching the film before its combination with non-woven material with subsequent implementation vacation layered structure or its compression, which leads to the formation of a pincushion, a high degree of fluffy layered structure consisting of a film and a nonwoven material in the areas between the bonds, in areas where the film and the nonwoven material remain firmly United. The present invention also provides a method of manufacturing such a composite material.

DETAILED DESCRIPTION OF THE INVENTION

Definition

In the present description the terms will be used with the following meaning, unless the context otherwise requires or will not be expressed any other value; in addition, singular, in common case, include the plural, and the plural, in common case, includes the singular, unless indicated other.

"Nonwoven fabric" means a fabric made of fibers or strands, which are formed by using a method, not a knitting or weaving, and which provides the links between some or all of the fibers or strands; however, such relationships can be formed, for example, using heat, adhesives or mechanical means, such as entanglement of the fibers.

"Fiber" means an elongated strand of a specific length, such as basic flocon can have the same or different length.

"Thread" means in General a continuous strand, which has a very large ratio of length to diameter, for example, 1000 or more.

"Yarn formed by the ejection of high-speed air flow" means non-woven material of the strands, which are formed by extrusion of molten polymer into strands, which are usually cooled with air supplied at high speed, to strengthen the yarn strands that are collected on the forming surface and often associated with the application of heat and pressure in a specific pattern. The formation of the yarn ejection of high-speed air flow is described, for example, in the following patents, the link to which can be done for additional details: U.S. patent 4340563 authors - Apple and others (Appel et al.), U.S. patent 3802817, the authors Matsuki and others (Matsuki et al.) and U.S. patent 3692618 authors - Dorsner and others (Dorschner et al.).

"Loop" means an area in which at least one fiber or strand separated from the other in non-woven material and includes, but is not limited to configurations in which the same fiber or strand does not necessarily overlaps itself, that is, for example, formed a complete circle or oval.

"Viescas fastener and which has projections to the profile, height, density, geometry and orientation such that they can be attached with the possibility of disconnection of the material of the loops of the fasteners in accordance with the present invention and provide the required level of properties hooks tensile and shear strength. These projections do not necessarily have to form a hook, but may have other configurations, such as a form of fungus. Suitable materials hooks can be unidirectional or bidirectional and often contain from about 16 to about 620 hooks per square centimeter, and the height of the hooks is approximately 0,00254 cm to approximately 0,19 see Such materials are supplied, for example, the firm Velcro INTERNATIONAL, Manchester, new Hampshire (Velcro International of Manchester, NH.), and 3M company in Saint Paul, Minnesota (3M of St.Paul, MN).

The term "amorphous polymer" is used here to describe a binder layer, used as a component of a multilayer film or separate overlay layer, which means a thermoplastic polymer, such as some of the polyolefin with a density in the range from about 0.85 to about 0.89 as of low crystallinity, for example, less than approximately 30%tx2">

"Thermal point connection comprises passing the fabric or material of the fibers, which must be connected between the heated flatting roller and thrust roller. Flatting swath has a certain pattern, through which the connection will not be formed around the material throughout its surface. As a result, for the calender roller has developed a number of patterns from the point of view of functional and aesthetic aspects. As will be clear to experts in this field, the magnitude of the percentage surface area with ties on the need described more or less in certain ranges, as the joints are usually thinned and over time wear out. For professionals in this field also it is clear that the designation "studs/inch2" and "connections/inch2" are to some extent interchangeable studs hard roll will create links in the substrate is essentially the same size and relationship of the surface area as the actual studs, located on a hard roll. For non-woven material, one example of a pattern has points ties with a pattern called pattern Hansen Pennings or "H&P" (Hansen Pennings or "H&P"), in which the area of STS U.S. patent 3855046, authors - Hansen and Pennings. Pattern H&P has a square region of pixels ties or pins, where each pin can have a width equal of 0.038 inches (0,965 mm), for example, that allows to obtain a pattern having a surface area links approximately 30%. Another typical pattern of connection points is an advanced pattern links Hansen and Pennings or "ENR" (Expanded Hansen and Pennings), which allows to obtain the surface area of the links from approximately 15% to 18%, which can be formed using square studs having, for example, the size of the hand, equal 0,037 inches (0,94 mm), and the density of the pins is approximately 100 pins/inch2(15.5 connections/cm2). Another typical pattern point connection, referred to as "714", has an area points of communication with square pins, where each pin can have a width equal to, for example, is 0.023 inch (0.58 mm), with a surface area relationships from 15 to 20% and approximately 270 studs/inch2(42 connections/cm2). Other common patterns include a diamond pattern ramish" ("Ramisch") with a repeating pattern of diamond-shaped, having a surface area relationships from 8 to 14% and 52 pins/inch2(8.1 connections/cm2), as well as uwasa from 15 to 20% and 302 studs/inch2(46.8 pins/cm2). Usually a percentage of the surface area of relationships varies widely from approximately 10% to approximately 30% of the surface area of the layered tissue, and the number of pins/inch2also may vary within a wide range. From a virtually infinite number of combinations of configurations of relationships, but only some patterns of ties may be used in accordance with the present invention. They will have a surface area relationships in the range of from about 5% to about 30%, preferably in the range of from about 10% to about 25% and the density of pins in the range from approximately 50 to approximately 200 pins per square inch (7,8-31 pins per square centimeter), preferably in the range of from about 75 to about 125 pins per square inch (the 11.6-19.4 pins per square centimeter). When used in this description, the term "nonwoven material" with a pre-established relationship means a non-woven material, in which the links were created with a pattern defined as used in accordance with these parameters. As is well known in the art, the bond spots allows you to keep the layers of the layered structure with each layer.

Examples of decorative patterns used for bonding the layered structure, which are used to create secondary links or for the connection of non-woven material with a pre-established relationship with the film are patterned "S-Stars" or "Baby items" (C-Stars or Baby Objects), which is shown in Fig. 5 and 6. The pattern With the Asterisks represents a transverse line pattern, or a pattern in the form of ribbed "velvet", which is interrupted by flying the stars and in General has a percentage of surface area ties approximately 17%, and the pattern "Baby items" (which is also described in the jointly submitted a U.S. patent for an industrial design 356688 authors - Uitenbroek and others (Uitenbroek et al.) on March 28, 1995) has a surface area relationships in a range from approximately 12% to approximately 20%.

Test methods

Hidronor: Measuring the barrier properties of the fabric to the penetration of liquids is geranamine test. Geranamine test determines the height of water (in millibars), in which the fabric will retain liquids before a certain amount of fluid will pass through it. Higher values of hidronor indicate that the fabric is a pressure to perform in accordance with the Federal Standard test method A, method 5514.

Burst tests during capture: burst Test when capture is a measure of the effort to break and the elongation or deformation of tissue that is subjected to unidirectional stress. This test is known in the art and conforms to the specifications of the method 5100 of Federal Standard methods of tests A. The results are expressed in pounds or grams required to break and percent elongation before rupture. Higher values indicate a stronger and more tensile fabric. The term "load" means the maximum load or force, expressed in units of weight required to break or rupture of the sample when testing for the gap. The term "total energy" means the total energy under load depending on elongation curve and is expressed in units of weight-length. The term "elongation" refers to the increase in length of the specimen during the test gap. When tests break when capturing using the two clamps, each of which has two jaws, each jaw has a surface in contact with the sample. The clamps hold the material in a certain plane, usually vertically, at a distance of 3 inches (76 ri capture and elongation at capture are obtained by using the sample size of 4 inches (102 mm) by 6 inches (152 mm), with dimensions of square jaws 1 inch by 1 inch (25 mm) and at a constant rate of elongation of 300 mm per minute. Used a broader sample than sponge clamps to obtain representative results, the effective tensile strength of the fibers sandwiched in width, together with the additional strength, which creates an additional fibers in the fabric. The specimen is clamped in, for example, the tester of the type sintek 2 (Sintech 2), the company supplied Sintek Corporation (Sintech Corporation, 1001 Sheldon Drive, Cary, North Carolina 27513, model type Instron Model TM (1001 Sheldon Dr., Cary, NC 27513, an Instron Model TM), the company supplied Instron Corporation 2500, Washington Art. , , Canton, mA 02021 (Instron Corporation, 2500 Washington St. , Canton, MA 02021) or model Thwing-albert INTELLECT II (Thwing-Albert Model INTELLECT II) production Company Thwing-albert Instrument Co. , 10960 Dutton road, Philadelphia, Pennsylvania 19154 (Thwing-Albert Instrument Co. , 10960 Dutton Rd., Phila., PA 19154). This method closely simulates the conditions of a voltage of tissue in real use. Described in this description, the results represent an average value obtained by testing three samples, and tests can be performed with the samples in the transverse direction (MO) or the machine direction (MN).

Test lead: When test lead or test for delamination of the layered material, the layered material is tested for the amount of tearing efforts, which breaks up the layers of the layered material. Values tearing efforts are obtained by using a certain width of the tissue sample, the width of the jaws of the clamps and the constant expansion rate. For samples having side film side of the film sample is covered with a film mask or any other suitable material, so that the film is not torn during the test. The film mask is applied to only one side of the layered structure and does not contribute to the force to peel the sample. This test uses two clamps, each of which has two jaws, each jaw has a side in contact with the sample, in order to keep the material in one plane, usually vertically, with a distance of 2 inches (51 mm) at the beginning of the gap. A sample size of 4 inches (102 mm) in width and at such length, which is necessary to determine the adequate length of the specimen. Side of the sponge has a size of 1 inch (25 mm) in height, at least 4 inches (102 mm) in width and a constant rate of extension of 300 mm/min, the Sample is split manually to adequate the direction from each other with a specified rate of expansion, however, to break the layered material. The sample is broken at 180othe separation between the two layers, and the force on the gap, shown here, represents the average of three trials, with peak load expressed in grams. Measurement effort begins when 16 mm laminate was cut off from each other, and continues until all 170 mm layered structure will not be separated. Used tester Sintek 2 firm Sintek Corporation, 1001 Sheldon drive, Cary, North Carolina 27513, model Instron TM produced by Instron Corporation, 2500 Washington Art.,, Canton, Massachusetts 02021, or Thwing-albert Model INTELLECT II, manufactured by Thwing-albert Instrument Co., 10960 Dutton road, Philadelphia, Pennsylvania 19154. These tests can be performed with the sample in the transverse direction (MO) or the machine direction (MN).

Test Martindale abrasive wear: this test measures the relative abrasion resistance of the fabric. The test results are presented on a scale of values from 1 to 5, and 5 means the least wear and 1 the highest, after 120 cycles at a load of 1.3 pounds per square inch (0.09 kg/cm2). The test is performed with ispolzovanie firm James X. Hilo & company, LTD, West Yorkshire, England (James H. Heal & Company, Ltd. Of West Yorkshire, England). Used abrasive material, which represents the wheel of silicone rubber dimensions of 36 inches by 4 inches and a thickness of 0.05 inches (91 cm 10.2 cm 1.27 mm), reinforced with glass fiber, having a rubber hardness of the surface izmerennoe. A shore a 81 9. Abrasive material supplied by company to company F insulation Inc. (Flight Insulation Inc.), which is the distributor of the Connecticut Hard rubber end, 925 Industrial Park, NE, Marietta, GA 30065 (Connecticut Hard Rubber 925 Industrial Park, NE, Marietta, GA 30065).

The weight per unit area: weight per unit area of various materials described herein were determined in accordance with the methods of the Federal test A/5041. The size of the sample material was 15,24 15,24 cm, and for each material were obtained three values, and then determined their average value. The following values are average values.

The gap hooks: Test for breaking strength at an angle 180odesigned to measure how well the components of the hooks and loops are connected to each other, and it contains a compound material of the hooks with the EC at an angle 180o. The maximum load is recorded in grams as the average of the three highest values of peak load required to detach or separation of these two materials. To perform this test requires the application continuously increasing efforts in the tester with a full scale load of 5000 grams, such as Syntec Systems 2 Computer Integrated Testing Systems, manufactured by Syntec, Inc., which has offices at the research Triangle Park, North Carolina (Sintech System 2 Computer Integrated Testing System, available from Sintech, Inc., Research Triangle Park, N. C.). This uses a sample of the material of the loops of size 3 inches (7.6 cm) to 6 inches (15.2 cm). The sample material hooks size 2.5 inches (6.3 cm), which are glued and connected to the ultrasound with essentially non-elastic nonwoven material, is placed side on which the hooks down on top of it and is placed on the upper surface so that it covers the material sample loops with an overlap of approximately one inch (25 mm). To ensure adequate and uniform connection of the hooks material with material eyelets, used the compacting roller, model LW 1, part number 14-9969 manufactured by Atlas electric Devices To. , , Chicago, illa state one cycle, thus one cycle passes through the compacting roller uses a weight of 40 pounds (18 kg). One end of the material of the tongue for engagement by the fingers, which is fixed on the material of the hooks is clamped by the upper jaws of the tester at the gap, while the end of the material eyes are directed to the upper jaw, is folded down and clamped the lower jaws of the tester at the gap. The location of relevant materials in the jaws of the tester on the gap should be adjusted so that in the respective materials was minimal sagging, and the length of the template was 3 inches (7.6 cm) before turning on the tester at the gap. Elements of hooks material hooks are oriented in a direction generally perpendicular to the intended direction of movement of the jaws of the tester at the gap. Tester at break is activated at a constant rate of separation of 500 mm per minute, and the maximum load in grams required to separate or rupture of the material of the hooks from the material of the loops at an angle 180owritten on the basis of the average of the three peak values.

Shear strength at break: a Test of the dynamic force of resistance to shear includes a compound material of the hooks with the mother of elec. The maximum load required to separate the hooks from the loops, measured in grams. To perform this test requires the use of the tester to break with constant velocity increment efforts with a full load of 5000 grams, such as Syntek 2 Computer Integrated Testing Systems. A sample of the material of the loops of size 3 inches by 6 inches (76 mm 152 mm) attached with ribbon mask on a flat surface of the holder. The sample material hooks size 2.5 inches to 0.75 inches (63.5 mm 19 mm), which are glued and connected to the ultrasound with essentially non-elastic nonwoven material, is located on top of and attached to the upper surface of the sample material loops in the shorter direction and 2 inches (51 mm) deeper from the edge of the slice. To ensure adequate and uniform connection of the hooks material with material eyelets used the compacting roller, model LW 1, part number 14-9969 manufactured by Atlas electric of Devices Co., , Chicago, Illinois (Model LW 1, part number 14-9969 from Atlas Electric Devices Co., Chicago, IL), to compress the United materials of hooks and loops per cycle, one cycle is equal to the aisle in the direction of MN (longer size) through the compacting roller using a total weight of 40 fontelera

The best option of carrying out the invention

The present invention will be described with reference to the drawings and examples, which illustrate certain variants of the embodiment of the present invention. To a person skilled in the art will understand that these options embodiments do not define the full scope of the present invention, which can be widely applied in the form of various modifications and equivalents in accordance with the attached claims. It is expected that the claims cover such modifications and equivalents.

Let us consider Fig. 1, on which is which forms by extrusion film 10 with the filler, which is then routed through the guide rollers 42, rotating together with the supporting rollers, in section 44 oriented in the machine direction. During the orientation temperature of the film 10 will depend on its composition, but also on the ability of the film to pass air, and other required at the end of the process properties of the composite material. For example, in the case petelicki zipper retractable USB adapter cable-tion will affect the size is equipped with a substrate of non-woven material. In most cases, the film will be maintained at a temperature below its melting point, but not more than 10oC. the Need for heating of the film due to the fact that it must quickly be stretched without the formation of any defects therein. The heated film is stretched in the machine direction in section 44, orienting the film in the machine direction and which contains a rotating rollers 46. The rollers 46 can rotate at increasing speeds, which leads to stretching of the film in the direction of motion ("machine direction" or "MN"). The amount of stretching will depend on the required at the end of the process properties petelicki fasteners, but, in General, the film will be stretched by at least 300% of its initial glista applications, involving the use of films based on polyolefins, stretching, for example, is at least 200% of the original length of the film, but often this value is in the range from about 250% to about 500%. Section forming a nonwoven material, such as a section, which includes forming apparatus 48, the feed 50 strands of fibers on a substrate 52 which forms a non-woven material 54, which is then submitted to the connecting clamp formed by rollers 56. This pre-fitted connections, non-woven material 30 is connected with the formation of the laminate film 10, when this is applied on the second pattern at the point of generation compression between the rollers 58. After creating a layered material using compression with heating or without it, these two layers of release, then layered material is wound with decreasing speed, for example, the value of which is equal to 80 to 90% of the speed at the site of compression, which allows the film 10 to be reduced, causing the formation of multiple folds on the surface layer 30. After reduction, the United layers may be subjected to operation holiday by contact with the heated roller or similar element, which rotates with the I. The temperature of the suspension may vary depending on the desired end process material properties loopy clasps and composition of the layers, but may be selected, for example, within the 15oWith the temperature used when stretching. After surgery vacation United layers can be cooled, for example by contact with air from the air scraper or cooling rollers, if necessary, or can be collected directly in the roll 60, or sent on a conveyor line for inclusion in the personal care product.

As will be clear to a person skilled in the art, the above process can be adapted for the production of various films and surface layers upon receipt permeable to air and impermeable to the air barrier materials used as loopy fasteners that have a wide range of properties. To work effectively as a material loopy fastener made in accordance with the present invention, when selecting the components of this material should take into account a number of factors. For example, a film having a low birth weight, should be strong enough that it could withstand all stages of the process, Eome this, the film should be able to effectively connect with outer layer and to maintain the barrier properties and rate of moisture vapor transmission. For many applications it is required that the stretched film was also given composite material opaque properties.

Film corresponding to such requirements include polymers, such as polyethylene, polypropylene, a mixture comprising polyolefin and such copolymers like ethylene and propylene, for example, in General, having a weight per unit area in the range from about 10 grams per square meter to about 50 grams per square meter and preferably for use as a loopy component in the range of from about 15 grams per square meter to about 30 grams per square meter. Specific examples include linear low density polyethylene, such as Dowlex2535, 3347 and 3310, Affinity5200, manufactured by Dawe Chemical company, Midland, Michigan (Dow Chamical Company of Midland, Michigan). The composition of the film preferably includes up to about 40 weight. % filler, such as calcium carbonate, and it would be preferable if such a filler would be from about 45 wt.% to about 65 wt.%. Samples include calcium carbonate brand Supercoat which contains the coating in an amount of about 1.5 wt.% of or stearic acid, or beganovi acid to improve the distribution of the filler. Particularly preferred examples of the film include jointly press film having on one or both sides of a thin outer layer of the amorphous polymer, such as polyalphaolefins thermopolymer, enriched with propene, or a copolymer, which allows you to link external layer without needing to impose a separate connecting layer. An example is a Catalloy polymer production company Montell, USA. Inc., , Wilmington, Delaware (Montell USA, Inc. of Wilmington, Delaware), which is a product of multi-olefinic reaction in which an amorphous statistical copolymer of ethylene propylene molecular mainly distributed in semi-crystalline continuous matrix vysokobarievogo monomer/nitroethylene monomer, an example of which is described in U.S. patent 5300365 the author - Oval (Ogale). In addition, a layer of amorphous polymer may also include fusible adhesives or other amorphous polyalphaolefins resin, which preferably have a melt viscosity of 100,000 MPa per second or more, in number, for example, to approximately 100 wt.% the layer. Commercially available amorphous poly-alpha-olefins, the invention and include, but not limited to, REXTACethylene-propylene, AREA E-4 and E-5 and a butylene-propylene VM-4 and BH-5, and REXTAC2301 production company huntsman Corporation, , salt lake city, Utah (Huntsman Corporation of Salt Lake City, Utah), and VESTOPLAST792 production company Hula A.,,, marl, Germany (Huls AG of Marl, Germany). These amorphous polyolefins are usually synthesized catalyst of Ziegler-Natta (Ziegler-Natta) and alkylamino socializaton and olefin, such as propylene, the nails are polymerized in combination with different amounts of ethylene, 1-butene, 1-hexane, or other materials to obtain mainly stereobitrate hydrocarbon chain. Also used some elastomeric polypropylene, such as described, for example, in U.S. patent 5539096, the authors Yang and others (Yang et al.) and in U.S. patent 5596092, the authors Resconi and others (Resconi et al.), which are fully provided here as a reference, and polyethylene, such as AFFINITY, EG 8200, the company Dow Chemical, from Midland, Michigan (Dow Chemical of Midland, Michigan), as well as EXACT4049, 4011 and 4041 company ackson, , Houston, Texas (Exxon of Houston, TX), and mixtures comprising one or more substances for enhancing adhesiveness, and substance KRATON< material with a bonding layer on one side may have an advantage, consisting in a higher rate of moisture vapor transmission, if required. Such films are described in more detail in co-assigned application for U.S. patent, registration number 08/929562 (reference number a patent attorney room 13257), registered on the same day in the name of MacCormack and Haffner (McCormack and Haffner), entitled "Layered structure of the film with filler, the air-tight" ("Breathable Filled Film Laminate") (Express mail RB 879662575 US), the contents of which are fully cited here as reference. Other layers of the film will be understood by specialists in this area when considering these descriptions of the examples.

The outer layer with a pre-established connections is chosen so that it was compatible with film or a binder layer and having properties such as weight per unit of area, volume and strength appropriate to its intended use. First of all, for economic reasons, non-woven materials are preferred, in particular nonwovens, formed with the ejection of high-speed air flow and having a weight per unit area lying mainly in the range from about 10 grams per square meter to about the approximately 25 grams per square meter. The composition of the outer layer is chosen so that it was compatible with the film layer, providing the required properties loopy fasteners. In the General case are synthetic polymers, such as polyolefins, for example polypropylene, polyethylene, mixtures thereof and copolymers comprising propylene and ethylene.

Such nonwoven materials described above and in the cited references, and their production is known to specialists in this field of technology. Specific examples include non-woven material, formed by the ejection of high-speed air flow, brand - ACCORDproduction company Kimberly-Clark Corporation, Dallas, Texas (Kimberly-Clark Corporation, Dallas, Texas). The pattern of relationships of the outer layer, as described above, is applied to create loops between the connections for the formation of areas of attachment under the complementary hooks. Currently used options include the use of advanced pattern RHT described in U.S. patent for an industrial design 239566 the author - Vogt (Vogt), pattern ENR, pattern Delta Dot (Delta Dot pattern), which contains a series shifted circular relationships with approximately 102 studs/inch2(16 pins/cm2) for the surface area with the, formed by the ejection of high-speed flow of air, is a "S" weaving pattern, which is described in co-assigned and concurrently registered the application for a U.S. patent (Registration number 08/929808, reference number patent attorney - 13324) in the name of McCormack, Fuqua and Smith (McCormack, Fuqua, and Smith), entitled "Patterns for connection of non-woven material, which allows to obtain a material with improved strength and wear resistance" ("Nonwoven Bonding Patterns Producing Fabrics with Improved Strength and Abrasion Resistance") (Express mail room EAT 331625424 US), which is incorporated fully herein by reference. In all cases, the percentage of the area would be less than about 30%, for example from about 5% to about 30%, and preferably from about 10% to about 25%, and preferably in the range of from about 75 to about 125/inch2(11,6/cm2- 19,4/cm2). The density of the links will be from about 50 to about 200/inch2(31/cm2). In addition to use as peelaway fastener coating preferably will have a tensile strength, measured as described above, at least 3000 g in the machine direction and at least about 1500 g in a direction transversely to the machine direction, and LASS="ptx2">

When using a separate overlay layer of amorphous polymer compound will be compatible with both the outer layer and the film layer and will provide a link between them without compromising the ability to skip a pair of moisture. It would be preferable if the connecting layer would be imposed by the blowing of the melt, for example, amorphous polyolefin, such as REXTAC2730 or 2330, production company Hunstman Corporation, , salt lake city, Utah (Hunstman Corporation, Salt Lake City, Utah). Issued from the melt layer, if it is applied with a low weight per unit area, for example less than 10 grams per square meter, preferably less than 5 grams per square meter, breathable and is efficient from a cost perspective. Other examples include the use of the material Vestoplast703, 704 and 508, the production company Hula AG, marl, Germany and nasl Starch NS 5610 production company nasl Starch Chemical company, Bridgwater, new Jersey (National Starch Chemical Company of Bridgewater, New Jersey), and elastomeric compositions described above.

Regardless of whether applied separate connecting layer or not, the joint strength between the outer layer and the film is measured using visheopisannie effort gap between the outer layer of hooks and complementary hooks, as measured by the above test gap hooks in order to prevent undesirable delamination of the layered structure. It would be preferable that the difference would be at least about 100, in Addition, for many applications, particularly as a substrate for personal care products, such as, for example, a diaper, a composite material must withstand a hydraulic pressure, which is measured using a burst pressure test, described in "test methods", equal to at least about 50 mbar (5 kPa) at the first drop, and preferably at least about 90 mbar (9 kPa). Especially when used as a substrate for products personal care disposable use of the composite material should have a measure of abrasion on Martindale equal to at least about 3, and it would be desirable - the rate of moisture vapor transmission of at least about 100 g/m2/24 hours, and preferably at least about 800 g/m2/24 hours. For this application, the breakout hooks, as measured by Federal Test Standard A, Method 5514, should preferably be in the range of from about 100 g to about 800 g, and the force of the resistance is to be in the range of from about 1000 g to about 6000,

Let us consider Fig. 2, which depicts a cross section of a variant embodiment of loopy component of a fastener made in accordance with the present invention. The front layer 114 consisting, for example, from a material formed by the ejection of high-speed air flow, contain the pattern, due to the presence of regions 115 (Fig. 2A) with a pre-established relationships, which differs from the pattern of links 112 of the layered structure. Loops 110 between regions 112 links of the layered structure are formed in the outer layer 114, which is formed by the ejection of high-speed air flow and which is connected together with press film 116 containing the connecting side or layer 118 with relationships and the base layer 120, in each of the links 112 of the layered structure. As shown, region 110 loops consist of strands or fibers that are not related to jointly press film 116 and which can cling to the elements 122 complementary hooks 124. As shown, a layer of hooks and layer loops split partly for more complete understanding. In Fig. 2A presents an enlarged image of the area shown in the circle in Fig. 2, which depicts a single item pattern pre-loopy component, made in accordance with the present invention and as substrate material for personal care products disposable use, namely for of the diaper. The diaper 210 contains a gasket 212, absorbent 214 and the substrate 216. As it is well known that urine passes through the spacer 212 and is absorbed by the absorbent 214, while the substrate 216 (shown partially cut-out, allowing you to see the layers 118 and 120 (Fig. 2A for clarity of understanding) is impervious to urine and prevents leakage. In this case, the entire substrate is formed from a material loopy fastener made in accordance with the present invention, as described with reference to Fig. 2, with the location of the non-woven eyelets on the outside. This provides essentially infinite level adjustments at the connection line elements 218 fasteners. When using the hook elements 218 can be stretched to a comfortable fit and fastened anywhere on the substrate 216. Then, if you need more adjustment, hook elements 218 may be simply detached home and re-installed at another location of the substrate 216. In preferred embodiments the embodiment of the strip passes in pairs is used on non-woven with pre-established relationships, made in accordance with the present invention. In Fig. 4 shows the pattern "baby items", obtained as described above, area 400, equipped with a pre-established connections, and Fig. 5 shows the pattern "S-stars", obtained as described above, area 500, equipped with a pre-established connections.
