Description

Self-adhesive fabric (2)

This case relates to a self-adhesive fabric, in particular, the first side and the second side of a fabric have a mutual fastening function.

According to the conventional self-adhesive fabric, as shown in the National Invention Patent No. I388291 (corresponding to US Patent No. 8,551,596) owned by the applicant of this case, the self-adhesive fabric includes a hook structure And a hook structure, the loop structure is woven from the composite spinning yarn, and then opened, and decomposed into more microfibers, so as to form a loop between two interwoven points of the yarn; and the hook The tissue is a blended interwoven fabric composed of hot-melt artificial staple fiber blended yarn, which is woven together with ultra-fine fiber yarn by a shuttle loom or knitting machine, and sintered to fuse the artificial staple fiber fluff on the surface of the fabric into a bead. Shaped end, making it the hook part corresponding to the hook and loop.

However, in practice, the loop tissue is used to bind the corresponding hook tissue, so the looseness of the fiber loops of the loop tissue affects the hook and loop function of the hook and loop fabric. However, after the pure composite fiber yarn is opened, if the other fibers with different heat shrinkage ratios are not included, the surface of the ring structure will be a flat and dense cloth pattern, and the surface of the ring structure cannot be fluffy. These fiber loops lose their hook and loop function.

In addition, if the weight content of the hot-melt staple fiber yarn in the hook structure is less than 50%, after the non-thermofusible fiber contained in the hot-melt fiber is burned out in the sintering process, the number of remaining fencing fibers will decrease Its hook and loop function.

The main purpose of this case is to provide a self-adhesive fastening fabric, which includes a first surface and a second surface, and the first surface and the second surface have a function of fastening each other.

Another purpose of this case is to provide a self-adhesive fabric that can be cut at will according to the shape of the product, but still can be fastened to each other at will, which greatly releases the freedom of product design.

In order to achieve the foregoing objective, the technical means adopted in this case is to provide an auto-adhesive fabric, which is at least made of a loop tissue and a hook-organization. The auto-adhesive fabric has a first surface and A second surface, the first surface and the second surface have both the loop tissue and the hook tissue, and the area of the loop tissue on the first surface is the hook tissue A predetermined multiple of the area of the area, and the area of the hook tissue on the second surface is the predetermined multiple of the area of the ring tissue, and the predetermined multiple is greater than or equal to two; The constituent fibers of the loop structure include woven with at least one heat-shrinkable fiber yarn, and the surface of the loop fabric has a plurality of fiber loops generated by a heat shrinking process; and the constituent fibers of the hook structure include At least one kind of hot-melt fiber yarn is woven, the surface of the hook tissue has hairiness and a plurality of fettered fibers that have curled and / or beaded ends after a scorching process; when the first surface is The ring tissue and the second face When the hook tissue on the upper surface is in contact with each other, the fiber loop and the binding fiber may hook or bind with each other, so that the first surface and the second surface form a hook-and-loop effect.

In order to achieve the foregoing object, another technical means adopted in the present case is to provide an auto-adhesive fabric, which is woven at least by a loop tissue and a hook-organization. The auto-adhesive fabric has a first Surface and a second surface, the first surface has the ring structure, and the second surface has the hook structure; wherein the constituent fibers of the ring structure include at least one heterothermal shrinkable fiber The surface of the loop fabric has a plurality of fiber loops generated by a heat shrinking process; and the constituent fibers of the hook tissue are woven from at least one type of hot-melt fiber yarn, the hook The surface of the outer tissue has hairiness and a plurality of fetter fibers that have curled and / or beaded ends after a scorching process; when the ring tissue on the first surface and the When the hook tissue is in contact, the fiber loop and the binding fiber may hook or bind with each other, so that the first surface and the second surface form a hook-and-loop effect.

Basically, as shown in FIG. 1, it is a first embodiment of a self-adhesive fabric 1, which is a 3/1 warp-face twill (3/1 warp- faced twill), the warp yarn 11a of the self-adhesive fabric 1 includes at least one hot-melt fiber yarn 111, and the weft yarn 12a includes at least one different heat-shrinkable fiber yarn 121. A first surface 1 a of the 3/1 warp twill weave is used as the hook tissue 11, and a second surface 1 b is used as the loop tissue 12. Viewed from the first side 1a of the self-adhesive fabric 1, it shows a 3/1 warp twill weave, and the floating point number of the warp yarns 11a is three times that of the weft yarn 12a; at this time, the first The surface 1a serves as a hook tissue surface. Therefore, the area occupied by the hook tissue 11 on the first surface 1 a is three times that of the ring tissue 12. Therefore, after weaving the 3/1 warp twill weave, most of the hot-melt fiber yarn 111 appears on the first side 1a.

As shown in FIG. 2, it shows the reverse side of the self-adhesive fabric 1 shown in FIG. 1, that is, the second surface 1 b. The second surface 1 b is a 1/3 weft-faced twill) organization, the floating point number of the weft yarn 12a is three times that of the warp yarn 11a, so the area occupied by the loop tissue 12 on the second surface 1b is three times that of the hook tissue 11; The two surfaces 1b serve as a ring-shaped tissue surface. Therefore, after weaving the 3/1 weft twill weave, most of the heterothermal shrinkable fiber yarn 121 appears on the second surface 1b, so that the first surface 1a and the second surface 1b of the self-adhesive fabric 1 Has an excellent interlocking function. The warp yarn 11a and the weft yarn 12a may contain elastic fibers, for example, polyurethane elastic fibers such as "LYCRA" or "OPELON", so that the self-adhesive fabric 1 has elasticity in the warp direction and / or the weft direction.

As shown in FIG. 3, the warp yarn 11 a of the hook structure 11 is composed of the hot-melt fiber yarn 111. The hot-melt fiber yarn 111 may be selected from short fiber spun yarns such as 10's to 80's. The hot-melt short fibers used in the short-fiber yarn are cut into long polyester fibers of an appropriate length. The long polyester fiber may be selected from, for example, 75de / 72f, 150de / 48f, 150de / 36f, or 450de / 96f, etc., and the single fiber size of the hot-melt fiber yarn 111 ranges from about 1.04 de / f to 4.69 de / f. Or it is 5de / f or less. Therefore, the hot-melt short fibers can be blended with natural short fibers into a blended yarn to have different functions. The hot-melt fiber yarn 111 is selected from polyester yarn, polyethylene yarn, polypropylene yarn, nylon yarn, or polymethyl methacrylate yarn.

The hook structure 11 passes through a scorching process to form the frustrated fibers 112 containing the hot-melt short fibers into a curled shape 113 and / or a beaded end 114. The natural short fibers will be burned in the scorching process, leaving only the fetter fibers 112 formed by the hot-melt short fibers, so the hot-melt short fibers occupy the hook tissue 11 For example, more than 50% of the weight of the blended yarn is better in order to provide enough of the tether fibers 112. The hot-melt short fiber may be selected from materials such as polyester, polyamide, polyolefin, and polypropylene cyanide. In this embodiment, the surface of the hook structure 11 has hairiness, and the hairiness naturally protrudes from the surface of the hot-melt fiber yarn 111 through the spinning process through the hot-melt short fiber, wherein the hot-melt fiber The implementation of the yarn 111 is preferably a ring-spun yarn because the number of hairs of the ring-spun yarn is large. Therefore, the hook structure 11 formed by the ring-spun yarn has a better hook-and-loop effect.

The hot-melt fiber yarn 111 can also be selected from long-fiber winding yarns, such as 75de / 72f, 150de / 48f, 150de / 36f, or 450de / 96f. The individual fiber size of the long-fiber winding yarn is from about 1.04 de / f to 4.69 de / f, or 5 de / f or less. The material of the long-fiber winding yarn can be selected from polyester, polyamide, polyolefin, or polycyanide.

Since the surface of the long-fiber winding yarn does not have hairiness, it is necessary to apply a feathered raising process to the first surface 1a, which has a large area occupied by the hook structure 11, in order to make the hook A part of the fibers on the surface of the partial tissue 11 is abraded to generate a plurality of dense fleece fibers 112. Therefore, the fetter fibers 112 all appear on the first surface 1a, and then the hot-melt-containing property is passed through the sintering process. The fetters 112 of the fibers form a crimp 113 and / or a beaded end 114.

The hair feathers of this embodiment are formed through the sanding process, so the hair feathers only appear on the surface of the hook tissue 11 after the sanding process. Therefore, the time and the brush of the sanding process can be adjusted. Or the type of matte paper, the number and length of these hairs can be selected, and the hook tissue 11 can be produced with various hook and loop strength, according to the needs of different products.

The single fiber size of the hot-melt fiber is selected from 1.04 de / f to 4.69 de / f, or less than 5 de / f, so as to correspond to the size of the plurality of fiber loops 122 of the ring structure 12, so that Produces the best mutual fencing function, but the single fiber size is not limited to this. The hot-melt fiber may have a plurality of micropores in the hollow cavity and / or the surface to expand the surface area and make the hook tissue 11 have the functions of moisture absorption and quick-drying. Furthermore, the hot-melt fiber yarn 111 can be further sanitary processed or interwoven with silver-plated fibers, so that the hook tissue has an antibacterial function. In addition, the hot-melt fiber yarn 111 is further combined with metal fibers, such as silver-plated fibers, copper fibers, or graphene fibers, and has antistatic and conductive functions. In addition, the hot-melt fiber yarn 111 may include the aforementioned elastic fibers so as to have stretch elasticity.

As shown in FIG. 4, the weft yarn 12 a of the ring structure 12 includes at least one hetero-heat-shrinkable fiber yarn 121, and the hetero-heat-shrinkable fiber yarn 121 includes a first fiber 123 having a first heat-shrinkage rate. 30de / 12f polyester fiber with a shrinkage rate of 15% or more, and a second fiber 124 having a second heat shrinkage rate, such as 50de / 144f polyester fiber with a heat shrinkage rate of about 3%, the first heat shrinkage rate If it is larger than the second thermal shrinkage ratio, it is better that the difference between the thermal shrinkage ratio of the first fiber 123 and the second fiber 124 is more than 7%. The hetero-heat-shrinkable fiber yarn 121 has a different heat-shrinkage rate due to a heat-shrinking process, such as the high temperature of the dyeing process, so that the second fiber 124 is longer than the first fiber 123. Furthermore, the loop structure 12 is provided with a plurality of fluff loops 122 which are fluffy.

In this embodiment, the self-adhesive fabric 1 is heat-shrinked during the dyeing process, and the weft width of the self-adhesive fabric 1 is stretched in the subsequent heat setting process to adjust the first fiber. The proper difference between the shrinkage ratio between 123 and the second fiber 124 is fixed, and the bulkiness of the fiber loops 122 is adjusted again. The first fiber 123 of the first heat shrinkage rate is generally obtained by modifying the crystalline polyester to obtain a high heat shrinkage rate, which is a conventional technology, and is not described herein. If the second fiber 124 is a 50de / 144f polyester fiber, its single fiber size is about 0.347 de / f, which is thicker than the fiber produced by opening the composite fiber, and the second fiber 124 may not need to pass through a composite spinning. Silk process, so there is no need to go through the fiber opening process, in order to simplify the production process and increase its durability.

The second fibers 124 contained in the different heat-shrinkable fiber yarn 121 may be selected from segmented pie 80de / 72x12f (PET / Co-PET) or sea-island 75de / 24x37f. Ester composite fiber. The first fiber 123 is, for example, selected from 30de / 12f high heat shrinkage fiber, and the second fiber 124, for example, is selected from composite spinning fibers. Spinning dissociates into about 0.09 de / f fiber, and the high temperature of the chemical fiber opening and / or dyeing process causes the heterothermally shrinkable fiber yarn 121 to have a different thermal shrinkage rate, causing the second fiber 124 to be different from the first fiber 124. A fiber 123 is long, so that the loop tissue 12 has a plurality of fiber loops 122 which are fluffy. Therefore, when a thinner fiber yarn, such as the polyester composite spinning, is used as the loop structure 12, it is suitable for light and thin fabrics. Therefore, if the second fiber 124 is the composite spinning fiber, the single fiber size is 0.3 denier or less, and the composite spinning fiber can be decomposed into more ultrafine fibers through the chemical fiber opening process if necessary. .

When the first embodiment of the self-adhesive fabric was implemented, the selection range of the size of the bond fiber 112 was approximately 1 de to 5 de, and the selection range of the size of the fiber loop 122 was approximately 0.08 de to 2.0 de; The larger the size difference, the easier it is to stick to each other, but the durability is inversely proportional to the fiber fineness. For example, the preferred combination of the bond fiber 112 of 150de / 48f and the fiber loop 122 of 50de / 144f, or 75de The fettering fiber 112 of / 36f is matched with the fiber loop 122 of 80de / 72x12f, but it is not limited thereto. In addition, the hetero-heat-shrinkable fiber yarn 121 may include the aforementioned elastic fibers, so that the hetero-heat-shrinkable fiber yarn 121 has elasticity.

Since the first fibers 123 can generate a large shrinkage during the dyeing process and shorten the distance between the two adjacent intertwined points, the thermal shrinkage of the second fibers 124 is relatively small, which forces the second fibers 124 in the A relatively loose floating yarn is formed between two adjacent interlaced points of the weft yarn 12a to produce a fluffy loop 122 of these fibers. The composite spinning can also use polyester and polyamide (PET / PA6) co-spinning spinning method. After the fiber is opened, fibers of both polyester and polyamide can be formed; the two types of heat shrinkage It is better that the difference in thermal shrinkage between the first fiber 123 and the second fiber 124 is greater than 7%. If the hetero-heat-shrinkable fiber yarn 121 of the ring structure 12 contains the first fiber 123 with a higher heat-shrinkage rate, the self-adhesive fabric 1 can be made richer, and thus can be used as a scarf with a self-adhesive function. And has a warm purpose.

As shown in FIG. 5, an example of the application of the self-adhesive fabric 1 as a one-sided wrap towel. When covering an article, the first surface 1a and the second surface 1b of the self-adhesive fabric 1 are adhered to each other. The buckle eliminates the trouble of knotting and knotting of the traditional bag towel, which is convenient and can increase the space for the bag to cover the articles. In addition, the mutual fastening function of the first surface 1a and the second surface 1b of the self-adhesive fabric 1 can also prevent the bandage bandage from slipping out during bandage and is more efficient. The length of the bandage is shortened, and the speed and quality of the bandage are greatly improved.

The self-adhesive woven fabric 1 can also be implemented with 2/1 warp twill weave, 4/1 warp twill weave, and 5 warp-flush satin weaves. The floating point number ratio is 2 times, 4 times, and 5 times, respectively, and the occupied area is 2 times, 4 times, and 5 times respectively; and the larger the floating point number ratio, the larger the span of the floating yarn, making the fabric The softer the 1 is, the longer the fiber loops 122 are, but the fetter fibers 112 of the hook tissue 1 are relatively soft. Therefore, the 2/1 warp face twill weave with a smaller floating point number not only has a smaller floating yarn span, but also more warp yarns 11a appear on the second face 1b, and more weft yarns 12a appears on the first side 1a. In other words, it is equal to reducing the hook tissue 11 of the first surface 1a, and at the same time reducing the loop tissue 12 of the second surface 1b, thereby reducing the mutual sticking function. Therefore, in principle, the woven fabric preferably has a 3/1 warp twill structure, a 4/1 warp twill structure, and a 5-end satin structure. As shown in FIG. 6, five 5-end warp-flush satin autologous velcro fabrics 1 are shown.

Therefore, from the description of FIG. 1 to FIG. 4 and FIG. 6, it can be found that the self-adhesive fabric 1 is at least woven by a loop tissue 12 and a hook-part tissue 11. The self-adhesive fabric 1 has a A first surface 1a and a second surface 1b, the first surface 1a and the second surface 1b having the ring tissue 12 and the hook tissue 11 at the same time, and the area of the ring tissue 12 on the first surface 1a Is a predetermined multiple of the area of the hook tissue 12, and the area of the hook tissue 11 on the second surface 1b is the predetermined multiple of the area of the ring tissue 12, and the predetermined multiple is greater than or equal to two.

The constituent fibers of the loop structure 12 include at least one hetero-shrinkable fiber yarn 121, and the loop structure 12 has a plurality of fiber loops 122 generated through a heat shrinking process. The constituent fibers of the hook structure 11 include at least one hot-melt fiber yarn 111, and if the hook structure 11 is composed of a hot-melt long-fiber yarn, it must have a sanding process to make the hook structure 11 has hairiness on the surface, and then a scorching process is performed to generate a plurality of crimped fibers 113 and / or beaded ends 114. If the hook structure 11 is composed of hot-melt short-fiber yarn, the surface of the hook structure 11 already has hairiness, so only a plurality of curled 113 and / or beaded ends 114 need to be generated through a single burn-out process. Bound fiber 112.

When the ring tissue 12 on the first surface 1a and the hook tissue 11 on the second surface 1b are in contact, the fiber loops 122 and the tie fibers 112 may hook or tie each other, so that the The first surface 1a and the second surface 1b form a hook-and-loop effect.

As shown in FIG. 7, it discloses a second embodiment of the self-adhesive fabric. The self-adhesive fabric 1 is a double-face pique fabric with a knitted double rib texture. A first surface 1a of the button fabric 1 is used as a hook structure 11 and is woven from a double-ribbed structure including a hot-melt fiber yarn 111. A second surface 1 b of the self-adhesive fabric 1 is used as a loop structure 12, and is woven from a single-sided structure including a hetero-shrinkable fiber yarn 121.

The first surface 1a is tucked into a plurality of connection points with the second surface 1b to form the self-adhesive fabric 1. The hoisting organization forms a recessed hole in the first surface 1a, and hides these connection points in the recessed hole, so that the first surface 1a is all the hook tissue 11 and the second surface 1b is all Organize the ring 12 and vice versa. Therefore, the double rib pattern can be used to make the first surface 1 a both be the hook tissue 11 and the second surface 1 b all be the ring tissue 12.

The self-adhesive fabric 1 of the second embodiment is woven from a rib knitting machine with a plurality of hetero-heat-shrinkable fiber yarns 121 and a plurality of heat-fusible fiber yarns 111. The isothermally fusible fiber yarn 111 is fed and woven through a plurality of knitting needles on a dial and a cylinder, respectively. If the different heat-shrinkable fiber yarns 121 of the loop structure 12 are fed and woven by the knitting needles on the dial (that is, the loop structure 12 is composed of yarns on the dial of the knitting machine) ), The hot-melt fiber yarns 111 of the hook tissue 11 are fed and woven by the knitting needles on the needle cylinder (that is, the hook tissue 11 is made from the needle cylinder on the knitting machine). Made of yarn) and vice versa.

In the second embodiment, the hook structure 11 may be composed of hot-melt short-fiber yarn or hot-melt long-fiber yarn. If the constituent fibers of the hook structure 11 are hot-melt short-fiber yarn, then only In this scouring step, the interlocking fibers 112 containing hot-melt short fibers are formed into a crimped shape 113 and / or a beaded end 114. If the constituent fibers of the hook structure 11 are selected from hot-melt long-fiber yarns, the first surface 1a must be subjected to the sanding process and the scorching process to produce a curled 113 and / or beaded end 114. A plurality of tie fibers 112. The second surface 1b is composed of the ring structure 12 composed of the hetero-heat-shrinkable fiber yarn 121. After the heat-shrinking process, a plurality of fiber loops 122 are generated, so that the first surface 1a of the self-adhesive fabric 1 and The second surface 1b is the hook tissue 11 and the ring tissue 12 each other, and therefore has a function of sticking to each other.

As shown in FIG. 8, it discloses the third embodiment of the self-adhesive fabric. The self-adhesive fabric 1 is a plain jersey knitted fabric. The knitted fabric will be different The heat-shrinkable fiber yarn 121 and a heat-fusible fiber yarn 111 are superimposed, and then woven with a single-sided knitting machine. If the hot-melt fiber yarns 111 of the hook structure 11 appear on the first surface 1a, the hetero-heat-shrinkable fiber yarns 121 of the ring structure 12 must appear on the second surface 1b, and vice versa . In this embodiment, the first surface 1 a is all the ring-shaped tissue 12, and the second surface 1 b is all the hook-shaped tissue 11.

As mentioned above, the constituent fibers of the hook structure 11 of the first surface 1a may be composed of hot-melt short fiber yarns or hot-melt long fiber yarns. In the wool process, the fusing fibers 112 containing the hot-melt fibers are formed into a curled shape 113 and / or a beaded end 114. If the constituent fibers of the hook structure 11 are selected from hot-melt long-fiber yarns, the first surface 1b must be subjected to the sanding process and the singeing process to produce a curled shape 113 and / or a beaded end 114. The plurality of tie fibers 112. The second surface 1b is composed of the ring structure 12 composed of the hetero-heat-shrinkable fiber yarn 121. After the heat-shrinking process, a plurality of fiber loops 122 are generated, so that the first surface 1a of the self-adhesive fabric 1 and The second surface 1b is the hook tissue 11 and the ring tissue 12 each other, and therefore has a function of sticking to each other.

As shown in FIG. 9, it discloses a fourth embodiment of the self-adhesive fabric. The self-adhesive fabric 1 is a double-sided three-dimensional spacer fabric. The constituent fibers of the hook structure 11 of the first surface 1a of the double-sided three-dimensional fabric are composed of a hot-melt short fiber yarn or a hot-melt long fiber yarn. The constituent fibers of the ring structure 12 on the second surface 1b are composed of hetero-heat-shrinkable fiber yarn 121. The first surface 1a and the second surface 1b are connected to form the double-sided three-dimensional fabric through a connecting yarn 125. The connecting yarn 125 is selected from a monofilament, a long-fiber yarn, a short-fiber yarn, and the like. The constituent yarns of the first surface 1a and the constituent yarns of the second surface 1b of the three-dimensional fabric woven in this way have no direct connection points. Therefore, the first surface 1a can be all the hook structure 11 and the second All of the surfaces 1b may be the ring structure 12, and the first surface 1a and the second surface 1b of the self-adhesive fabric 1 may be the hook structure 11 and the ring structure 12 through the aforementioned processing steps. With mutual sticking function.

For the type of the connecting yarn of the double-sided three-dimensional fabric, for example, 30de / 1f nylon monofilament is used to make the three-dimensional fabric have a space between the first surface 1a and the second surface 1b, and have insulation and avoidance. Shock function. Of course, the connecting yarn can also be selected from general processing yarn to reduce its thickness.

Furthermore, the first side and the second side of the self-adhesive fabric 1 are basically a single-sided structure, but may also be a single-sided jacquard structure, so that the self-adhesive fabric 1 has a pattern texture and color. .

As described above, the constituent fibers of the loop structure 12 include at least one hetero-heat-shrinkable fiber yarn 121, and the loop structure 12 has a plurality of fiber loops 122 generated by a heat-shrinking process. The constituent fibers of the hook structure 11 include at least one type of hot-melt fiber yarn 111. If it is a hot-melt short fiber yarn, it is only necessary to perform a sintering process, so that the bond fibers 112 containing the hot-melt short fiber are crimped Like 113 and / or beaded ends 114. If the constituent fibers of the hook structure 11 are selected from hot-melt long-fiber yarns, the first surface 1a must be subjected to a sanding process and a burning process to generate a plurality of curled 113 and / or beaded ends 114. Bound fiber 112. When the ring tissue 12 on the first surface 1a and the hook tissue 11 on the second surface 1b are in contact, the fiber loops 122 and the tie fibers 112 may hook or tie each other, so that the The first surface 1a and the second surface 1b form a hook-and-loop effect.

Therefore, from the description of FIG. 7, FIG. 8 and FIG. 9, it can be found that the self-adhesive fabric 1 is at least made of a loop tissue 12 and a hook-part tissue 11. The self-adhesive fabric 1 has a A first surface 1 a and a second surface 1 b. The first surface 1 a has the ring structure 12, and the second surface 1 b has the hook structure 11. The hot-melt fiber yarn 111 and the 121 different heat-shrinkable fiber yarn may contain elastic fibers. The elastic fibers are, for example, selected from polyurethane elastic fibers such as "LYCRA" or "OPELON" to make the self-adhesive fabric. 1 It has stretch elasticity in the warp direction and / or the weft direction.

In terms of water repellency and moisture absorption, based on environmental protection issues, the tether fibers 112 of the self-adhesive fabric 1 can use water-repellent fibers to make them have a permanent water repellent function on one side and eliminate the water repellent processing process. The produced wastewater does not have the problem that the traditional water repellent agent is gradually removed from the fabric due to household washing, thereby polluting the environment. The size of the second fiber 124 of the hetero-heat-shrinkable fiber yarn of the ring structure 12 is about 0.08 de to 2.0 de. The slenderness of the second fiber 124 has a large specific surface area, so it is hygroscopic, making it It has functions of water repellent and moisture absorption on one side. In terms of dyeing, the tether fibers 112 and the different heat-shrinkable fiber yarns 121 can be cationic dyeable polyester fibers or anionic dyeable polyester fibers, or polytrimethylene terephthalate. ) Fiber, which can reduce the dyeing temperature to normal temperature and pressure, which can greatly save energy consumption.

In addition, in order to increase the tethering and covering performance, elastic fibers such as polyurethane fibers and polybutylene terephthalate fibers are added to at least the warp yarn 11a or the weft yarn 12a. Wait.

In addition, the hook tissue 11 can also use hollow fibers or special-shaped cross-section fibers, which has thermal insulation properties, can reduce weight, and increase hygroscopicity.

Therefore, through the implementation of this case, its benefits are:

(1) The thickness of the self-adhesive fabric can be effectively reduced, which is suitable for the use of travelling towels and household clothing storage.

(2) The self-adhesive fastener fabric does not need a base fabric or a base material. Since the fabric itself directly forms the loop tissue and the hook tissue, the fabric itself has a buckle function in addition to the fabric; therefore, borrowing Due to the softness of the fabric, it can be used directly as clothing, which is convenient to put on and take off, and is especially suitable for medical clothing.

(3) The single fiber size of the hook tissue formed by the self-adhesive fabric is much thinner than that of natural hair, so it will not irritate the skin, and will not hurt other clothes when washing.

(4) The positive and negative masks of the self-adhesive fabric can be woven together like cloth, the shape can be printed and cut at will, and it has a comprehensive velcro function; when used as a wrap and bandage, it can It can be used freely and can be used for unlimited purposes.
