Abstract

This invention relates to making nonwoven fabrics which are durable for machine washing and durable for other wet and hard use or abusive applications. The inventive fabrics comprise two layers of fabric sheet bonded together at closely spaced locations where the bonding includes fibers from both fabrics thoroughly involved with the binder. The inventive fabrics retain the qualities of a spunlaced nonwoven fabric which include low cost, comfort, drapability, softness, absorbency, breathability and others while having the durability comparable to traditional knitted or woven fabrics.

Description

487633 V. Description of the invention (i) Field of the invention The present invention relates to a spunlaced nonwoven fabric, and specifically relates to a spunlaced nonwoven fabric suitable for durable use and reuse. The present invention, more specifically, relates to suede-type materials. BACKGROUND OF THE INVENTION DuPont has manufactured and sold Sont ara⑫ spunlace nonwovens for many years. Such spunlace nonwovens have many uses, such as surgical gowns and drapes, absorbent wipes and durables such as window cleaners and clothing linings. S: ntara ⑥ spunlace nonwoven fabric has been successfully used in the city because of its low cost of use and its 4 shell characteristics, such as bedding, softness, comfort, drape and absorption. Du f = spunlace nonwoven fabric is made of fibrous fabric entangled with high-energy water jet nozzles. Twenty percent, * Evans et al. US Patent No. 3,485, 706 basically: Ϊ Ϊ Ϊ 可由 can be made from a variety of fibers , Such as polyacetate, cellulose (adducts. Non- pulp), acrylic and other fibers, and some fiber admixtures-the fabric can be sealed by adding appropriate additives to the fiber or fabric v Improved to include antistatic and antimicrobial properties, etc. However, after many: j: French non-woven fabrics and non-woven t-woven fabrics are generally made in addition to the single 4 ", and its durability. Therefore, the spunlace nonwoven fabric, in addition, large ^ ^ = clothing such as surgical gowns and protective clothing with limited use; The purpose of strong non-U ί knitting can be made at a much lower cost, which can be made to break down tangled fibers and effectively destroy the fabric; ^

487633 V. Description of the invention (2) Intended use ’Because the fiber may have a significantly worse appearance or may be damaged. On several occasions weaving the fabric ie almost always appears to have been torn. Non-woven companies in the creation of spunlaces have borrowed stitching patterns to line this problem. Fibrils or short yarns are extremely resistant to cyclic tension of the fabric or will not suffer from ordinary unreinforced shots. The stitchbonded structure has proven to be quite satisfactory and can tolerate hundreds of times and cost considerations, which may have led such other people to try to weave fabrics. Adhesives tend to make things more durable than they need to stiffen. For many uses, such as clothing mixtures, the second problem is their result. Adhesives can be felt anywhere on the surface after hardening. Humans in clothing may have quite a pair of dyes and prints, like fabrics where the agent becomes visible and unsightly. Has been tangled 丨; After under washing, fabric mg) or "worn π prepared 3 甬 ΔΑ d 1" such as pilling (P1 ~ A π sale) outside washing, ordinary jet spray method for non-purpose use is not useful In one method of fabric durability of outer fabrics, the fabric is introduced into the fabric to form a stitched structure and the solution is to knit into the fabric with a dense pattern. Therefore, the washed fabric is sprayed with a mesh method. Weaving fabrics are as durable and reproducible as performance I wash and rinse. However, the beautiful solution of the stitched appearance is hesitant. 'Adding adhesive to the fabric to make durable fabrics is quite stiff. In fact, weaving more adhesives. It is clear that stiffness and furniture are not the desired properties. It often spreads to the surface, which produces some undesired and will become very hard, and its expansion is shown in the table: ϋ. It is irritating to wear these materials. The second problem is that the fibers of the adhesive often do not respond. Therefore, the bonding 487633 V. Description of the invention (3) Resistant to numerous washing and irrigation or similar And the quality of fabrics available. " Non-woven fabric with self-jetting method is also widely known as' suede is a material that is thrown away because of its absorptive properties. Tianmiao Lianshi 焱 山 焱 is silent π Α RAN suede Made of treated animal skin. There are also many man-made suede-type materials with heteroabsorptive properties, but none provide extremely high durability and excellent invention. Summary of the invention It has now been discovered that a durable fabric can be formed from two layers. The composite fabric structure has the habit of two: bonding-starting and making the fabric sheet, but it is notable. The flow-spreading nonwoven fabric structure includes two layers of bonding-starting fabric, and the property of the compound. The relatively tightly separated discrete adhesive bond is composed of two layers of fabric and a fiber portion of the fabric. The surface is at least one layer. The invention has a further aspect to provide a natural Suede and other man-made suede materials = cheap and economical, with a brief description of the drawings S product °

Description of the invention ㈣ 84 Preheater 99 Composite fabric η yyyyyyyyy 85 Modified 85 Preheater A detailed detailed example of a preferred specific example is now Referring to FIG. 1 of the accompanying drawings, a device for manufacturing a composite fabric of the present invention is generally indicated by the number 10. Fig. 1 is a high-level diagram intended to convey a general understanding of the device and method without making the drawings too detailed. The preferred method basically consists of three generally separate steps, shown in order in Figure 1. The first step is to make two separate water-entangled sheets, which are made from the first and second fabric forming threads indicated by numbers 20 and 30 above and below the attached drawings. Methods for forming hydroentangled sheets are generally described in U.S. Pat. No. 3,797,074, et al. And U.S. Pat. No. 3,485,706, in Evans et al., Which are incorporated herein by reference. In the case of the second fabric forming thread 30, the method includes sending a fibrous wool layer 32 to an airlaid machine 35. The airlaid machine 3 5 includes a toothed diffuser roller 36 which rotates at a high speed with respect to the feed speed of the wool layer 32. The fibers are pulled out of the wool layer 32 by the diffuser roller 36 and sent to the air flow in the nozzle 37. The fibers on the conveyor belt 41, now commonly referred to as a web, are transported to a second conveyor belt 42, which is suitable for supporting the fiber web under a series of high-performance water nozzles generally designated by the number 45. High-energy nozzle entangles fibers

" 1. Generally speaking, the fabric is transported around the roller 49 so as to be entangled with water from below by being impacted by the second water spray nozzle 50. Thereafter, the fabric is dried with steam heating rollers 54 and 55 to produce a base fabric 59. 90 ° βα and the second fabric line 20 and 30 are basically similar, and the base fabric is manufactured separately. Preferably, the base fabric should be collected at the end of each line 20 and 30. The production speed of the bus bars 20, 30 and the composite combination line 60 (described below) can be adapted, and each line can be independently operated for the maximum time. Looking at the method of joining the fabric layers together, the composite combination line in the middle part of Figure 1 is generally represented by the number 60. The base fabric 59 is fed into a composite composite thread and a two-layer roll 62 is provided thereon with a mesh-like adhesive layer 6 of a thermoplastic netting. The network I layer 61 is shown in Fig. 3, and contains a very fine knotted mesh material. The thermoplastic material has a relatively small junction 63. The fine strands 64 of the thermoplastic material hold the mesh adhesive layers together and effectively govern the spacing of the bonding points of the composite fabric 99 or the netting. In the preferred configuration, the diameter of point 63 is less than 1 mm and is about 1 mm from the adjacent f63. The fine strands 64 are quite thin and only a few microns thick. These materials are commercially used in medical and automotive products and are available in |

Nephew, Appiieci Extrusion Technologies, and other sources. The second base fabric 29 is placed on the mesh adhesive layer 61 to form a sandwich. The fabrics 29 and 59 are above and below. The interlayer is then fed into the middle of the rolls 7 1 and 2 under a controlled temperature, pressure, and speed to calender the thermoplastic material in the mesh adhesive layer 61. By the surface tension of the molten thermoplastic material, the dots 63 of the mesh adhesive layer 6 form discrete adhesive beads 6 5 (see FIG. 5), so that the fine connecting strands 64 between the points 63 are split, and the material therein Lots of retraction into small balls

487633 —----—— V. Description of Invention (6) 65. At the same time, the difference is pressed into the small ball: the pressure encapsulates or encapsulates a considerable part of the fiber of the base fabric: the adhesive will make every-base fabric the same number of points. ^ A, ,, 7, 9 ^ " See Figure 5, the structure of the composite fabric can be #, the main aunt 7 the first f A: to show the interface between the two-layer base fabric 29 and 59 'it: the point of the fiber r . Fiber = Any = dimensional network. The fiber is described as having two entanglements: the fiber is preferably laid flat on the fiber-^ the fiber is pushed into the fabric "toward. After the fabric has been entangled with water, it is directed to the front. Z vector fibers and [Y fiber correction = middle up and down The extended Z contains most of the fibers, and the XY fibers continue to be seen, some of the fibers 78 have a water-entangled fabric. As shown in Figure 5 ::: It is a powerful combination of the two fibers M of the water-entangled fabrics so far. Contribution. Of course, the durability is provided by the durability, and even more so that the fiber is entangled. Not all are entangled in the Z direction. The ball is entangled to form a magnetic resistance * w. And the most durable fabric with armor f I, but as long as it has at least-non-mechanical

Entangling or wrapping [ίί open but discrete bonding points (straight; eight V related to the ball and the fiber of the 之 fabric) can be included in the present invention ": 65 included in the fabric, and does not extend to: u The other observations are that the small ball leaves the surface of the fiber and the surface of the fiber 77. Therefore, the composite fabric is used as a foundation to form the softness and appearance characteristics of the base fabric. Do not surface. Page 10 487633 V. Description of the invention (7) The ball 65 preferably encloses or surrounds at least one surface of at least one fiber at the border of the two base fabrics, and the quasi-77 surface. These fibers are at a distance of several fibers from the border. The fiber combination is: So, the degree to which the small ball of the mixture 6 5 enters the small ball can also be described by the percentage of the knife, the fruit fiber, and the accuracy, preferably == thick fabric per base fabric, HA + ^^ 軏 Jia is a ball that should not extend through 100% of the base: because of this, it spreads the taste adhesive to 80% to 90% of the possible surface ... there is about 10% or more of the base Fabric / In another aspect, better response ^ _ sound objects are trapped in the ball, although the bran is too invented Xi Ming Ifl is about making compound Although the material is durable, although the dry weight of the present invention; the weaving number is broken or does not exist, it is also very good. The fabric of the present invention-θ: river will be a coarse green product and can be shot and force with the conventional; After that, the thickness will swell after tight compression.

Separation bonding point = interconnection, then they will make the composite fabric more rigid composition stand, that is, two will not make a continuous film layer in the middle of the fabric, but will form if the water entanglement is sufficient to make the fiber: f connection also Does not penetrate the surface of the fabric. The surface layer can still be freely connected to each other and maintain the surface integrity and strength, especially in the washing or machine :; but it is soft, drapeable, flexible material, special, ah moth effect After ...

Base fabric dilute alcohol, as well as other vinyl, polyurethane, polyurethane, polypropylene and polyethylene as adhesives. Preferably the adhesive should be thermoplastic

487633 V. Description of the invention (8) State, when the base fabric is pressed together with a roller or other configuration and compressed, the small ball can be controlled. Although it is better to find, its direct adhesive should be applied to the person shown below. For a simple series of adhesive fabrics 5-9. A small amount of sticky dots are formed to form small dots that are evenly distributed while maintaining points. Applying to the composite layer 6 1 net has ideal characteristics. The small ball of matter fiber is explained. In fact, they are all protective. According to the surface of the fabric, the fibers are often small or sometimes, when knotted, laminated, the size is not the size of the fabric. In the middle, it is flat and wide. It is recommended that it should not be non-thick. The capacity of the adhesive particles is preferably comparable to that of π oozing out to π. It has been noted that the permissible limits of the fabrics of the present invention are often apparent, while the lower limit is permissible. Most of the results on a single millimeter ball are also best shaped. Another consideration is. However, it has become

The mesh adhesive layer 61 is applied in the form of a mat, but has been placed on a base fabric. Please refer to Fig. 4 for a developer applicator 80, which refers to a small amount of the adhesive mixture as drops, and adheres in a similar manner to a reticulated ball. The configuration of the drops may not be similar, but the distribution of the salty letter can be close enough to establish the bonding point or location to provide other desired or boundary fabrics. Although amorphous, it is in the quality of the adhesive. For reasons and circumstances, it is certain that the adhesive on the two sides of the two-layer weave. The term small ball means that it is most likely not spherical, because one side of the fabric can be hidden or covered by the jaw pressure. However, the extension of any side to one side is the adhesive. The upper limit of the pellet size may be surrounded by the adhesive. Each pellet will be less than 2 mm in space between the fabric layers. It is believed that when the balls are closely spaced from each other, it is recognized that when the balls are better spaced, they are more spaced apart, and the non-woven fabric is more durable.

Page 12 487633 V. Description of the invention (9) Composite fabric. For example, it may be appropriate to accompany a small ball with a gap of 4 to 5 millimeters in the middle of the opening and closing of the ball. At the same time, greater glare & π t 4 a ^ U may be possible. However, these intervals may imply or require large small balls, which will stride, adopt t, and tebebe penetrate the thickness of the fabric. Therefore, in this case, the fabric layer can be used as a base,, ^ animal husbandry .., ^ ^, moon phase can be prepared, or the adhesive may be extended to

surface. In a preferred configuration, the interval is A mm or less. ^ Or smaller, better for appointments! The activation of the adhesive requires a balance of considerations. For example, the speed through the jaw will depend on the melting point of the adhesive, the temperature of the heating roller, and the other factors that will affect the adhesion, including the diameter of ::::. The dot or pellet-shaped adhesive is preferably applied to the fabric by means of a stiffened roller. u not drill This system is another option that may speed up the manufacturing process: two fabrics, 、, and 俾. The roller does not have to heat the fabric from room temperature. To pre-heat one or set the lower roller 72 to be heated by hot oil or other heat source, and the two dry chains and 72 are pressurized at the pressure of the heating light 72. Therefore, it is preferable to heat the distance to the lower base fabric 29. However, the preheater can be placed in multiples, the farthest above the mirror is the word 82, 83, 84, and 85, or the Z% position that is considered acceptable, such as the number, the preheating of the mesh adhesive layer 6 1 has been It doesn't matter what cascade. It has been evenly distributed, and no two fabrics may fix the points when they are fixed. . ,,, ‘h ball or point joints. The 疋’ water edge knot, which should also be considered, is not the weaving technology of the present invention. Needle-punched fabrics, which have a Z-fiber orientation configured by the only web that benefits from physical puncture & gain, are intended to orient the fibers within the scope of the present invention. Can also be effective

487633 V. Description of the invention (ίο) It should also be noted that in some cases, it may be necessary to adhere non-woven fabrics, kappa fabrics, knitted fabrics, or materials made by techniques other than the down-jet method or stitch technology of the present invention. For example, it may be necessary to deny a low-weight non-woven fabric with a heavy-duty jet-jet method as a ‘: ΐ 2 soft-money back layer. The woven fabric is fixed to the non-woven fabric 1 by a spray-jet method or a needle-punched non-woven fiber surrounded by a sufficient amount of the agent, and the resulting fabric can withstand repeated washing. The following is a more detailed description of the fabric sample of the present invention: a layer of a thermoplastic fiber web such as Delnet (D fusible polyethylene 丨 »square green grams per square meter, comparison: Γ 0 ^ 3-0.5 square meters per square yard or 10.2_17 .0 g / m 2) flat on the middle of the second layer of non-woven fabric. The fabric layer should be at least 0.6 ring / square yard (20.3 grams / square meter) up to about $ ring / square when heating the close contact fabric or up to 8 hours when " non-preheated "fabric (Square gram) (271 g / m 2). The preferred range is about 009_4 0 嗝 / square yard (two 1.6 on / m 2). These two fabric layers can be made of cellulose products such as snail == 利 驮 赛 ( L y cece 丨) or thermoplastics such as polyacetate or polyamines or mixed with others to produce specific properties.

The first and the spray-spray method 4 'lamination are available. The explanation of the jet gauze is not clear. The top encounter is a hermit ugly turtle. However, the top surface appears to be more related to the outer stability of the laminated fabric. The stability of the material in the temperature measurement table is made of the second and second layers of non-woven woven inner (or outer) method of non-woven fabric. However, after the fact, the first water jet can be used. Stable). The unwinding of the heat roller and the adhesion to the bottom surface of the stabilizer turn to a top layer and a bottom surface to explain the needles that are not located in the Z-Meeting. The degree and stability of the pressure surface are the same by using the top surface of the object. After the optimization, the variable must be set to achieve the inner layer of the most unfavorable layer adjacent to the agent layer. The obtained energy should be kept in the direction of the axis in the lamination. Observe that the pressure and the radiation caused by washing and unwinding the area cause it to shoot. When the configuration of the pair of layers is a surface. The inner surface of the object can be better with the Hirth Theorem fiber. Even if the bottom surface makes the temperature and

In the example, the back edge system is made to provide the optimal top and top configuration. A string up is performed to give the top and bottom of the laminate some preheating. At the same time, wrap it on the hot roll 180 ° before using the jaw and wrap it on the cold roll 180 ° when leaving the mouth. Choose better unwinding and health

The head 'and small temperature and pressure range can easily make products with sufficient stability. Examples Examples of the fabrics of the present invention were prepared substantially as described below. Suede fabric is made of 20% jet-jet mesh grade 8630 and one layer of Delnet 530 according to the method disclosed in U.S. Patent Application 08 / 642,649, and sprayed

Equivalent products can be obtained by using direct or reactive dyes after alkaline washing by paddle or rotary dyeing. Natural (real) suede is made by kneading leather with oil. Typical artificial suede is made by treating a woven or non-woven fabric with a polymer. Description of the test methods used Unit weight, thickness and tensile (grasp strength and elongation) measurements are based on the ASTM D1 1 1 7 measurement method.

The absorption force and speed are measured using a gravity absorption tester (), which can be purchased from M & K Systems, in which the fabric bears a load of about 35 kg / m2. Basically, GAT measures the s (gat absorption) and velocity (gat velocity) of a liquid absorbed through a small hole in the device. The τ 1/2 time is the time when the fabric absorbs half of its total water absorption. The speed at T 1/2 is the slope of the absorption curve at D 1/2. Intrinsic absorptivity (i n t abs) is a measure of the amount of water absorbed by a fabric, expressed as a percentage of the fabric lining. The fabric samples were completely immersed in water and allowed to drip dry i H 77 minutes. The difference between the dry and wet weight of the sample divided by the dry weight of the sample, then multiplied by
