Description

Fabric with bonding function

This case is about a kind of fabric, especially a kind of fabric with fettering function.

According to the conventional hook and loop fabrics, for example, the Chinese invention patent No. I388291 owned by the applicant in this case (corresponding to the US Patent No. 8,551,596), the Chinese invention patent I559862, the US Patent Application No. 15/690,799 and the US Patent No. 15/690,799. Patent application No. 106101627, etc., these patents disclose a bonded fabric that has a plurality of bonded fibers that have curled and/or beaded ends produced through a singeing process. Due to the size of the beaded ends of these bonded fibers, Very small, and each bead-shaped end has a smooth surface, making the loop of fabric corresponding to the hook and loop easy to slip off, so it only has a horizontal binding function and lacks a vertical binding function. Therefore, when the aforementioned hook-and-loop fabric is used as a bandage, especially when it contains water, the end of the bandage is easy to peel off, causing the bandage to loosen and fall off.

Another point of view from the conventional Hook & Loop Fastener is that the end shape of the hook element composed of thick monofilaments is basically hook-shaped or mushroom-head-shaped, and the hook-shaped or mushroom-shaped ends of each hook element are The head-like appearance is consistent, and the distribution shows regularity and evenness. The thickness of the monofilament used in the hook element is about 300d/f or above, so it can only be used as a fastener and cannot be used as a complete product that is in direct contact with the skin, such as a bandage, etc. Even if the hook and loop fastener is used as a fastener for clothing The use of hook and loop fasteners can also easily damage clothes and even injure the skin, which needs to be improved urgently.

The main purpose of this case is to provide a fabric with a fettering function. At least one surface of the fabric has fettering hairiness at the end of the irregular deformation body, so that the fabric has a vertical fettering function for loop fabrics containing loops.

The main purpose of this case is to provide a fabric with a fettering function. The front and back surfaces of the fabric have fettering hairiness and loop structures at the ends of the irregular deformation body, so that the front and back surfaces of the fabric have a vertical mutual fettering function.

Another purpose of this case is to provide a fabric with a binding function. The front and back surfaces of the fabric have a vertical mutual binding function. The thickness of the binding fiber of the fabric is about 6d/f or less, so it can be directly used as a self-adhesive bandage. , without damaging the skin.

Another purpose of this case is to provide a fabric with a fettering function, in which at least part of the irregular deformation system is formed by hot-melt bonding and aggregation of a plurality of beads and/or columns.

Another purpose of this case is to provide a fabric with a fettering function. At least one surface of the fabric has fettering hairiness at the end of the irregular deformation body. Since the fettering hairiness at the end of the irregular deformation body expands the area of the original fettering fiber, it can be compared with ordinary fettering fibers. The loop structures of conventional fibers are intertwined with each other and are not necessarily limited to loop fabrics made of microfibers.

In order to achieve the foregoing purpose, the technical means adopted in this case is to provide a fabric with a fettering function, which is woven from at least one thermoplastic fiber yarn, and at least one surface of the fabric has a plurality of thermoplastic hairs, wherein At least a part of the thermoplastic hairiness forms the first bonded hairiness with a bead and/or a columnar end; it is characterized in that: at least a part of the thermoplastic hairiness forms a first bonded hairy end with an irregular deformation The second bonding hairiness enables the at least one surface of the fabric to produce horizontal and vertical bonding functions with the plurality of fiber loops.

In one embodiment, the at least one surface of the fabric undergoes a sanding and/or brushing process to form the thermoplastic hairiness.

In one embodiment, the first bonded hairs with the ends of the bead and/or the column are formed by the thermoplastic hairs through a singeing process; and the first bonded hairs with the ends of the irregular deformation The second bonded hairiness is formed by at least a part of the first bonded hairiness through a hot melt pressing process.

In one embodiment, the thickness of a single fiber of the thermoplastic fiber yarn is less than 6 denier.

In one embodiment, the fabric is selected from plain weave, twill and double-layer weaves of woven fabrics; or the fabric is selected from single-sided, double-sided and double-layer weaves of knitted fabrics.

In one embodiment, the thermoplastic hairiness is generated from the hairiness produced by the short fiber yarn during the spinning process, and may be subjected to a sanding and/or brushing process if necessary. to produce more such thermoplastic hairiness.

In one embodiment, the thermoplastic hairiness is formed by a shearing process through a plurality of loops protruding from the at least one surface of the fabric.

In one embodiment, the at least one thermoplastic fiber yarn includes an elastic fiber in at least one warp direction and/or one weft direction and is elastic.

In one embodiment, the thermoplastic fiber yarn is selected from long fiber yarn or short fiber yarn made of polyolefin, polyamide or polyester.

In one embodiment, the fabric is bonded to another fabric having the fiber loops corresponding to the Velcro fasteners in a back-to-back manner, so that the two different surfaces of the bonded fabric have mutual Velcro fastening functions.

In one embodiment, an elastic body is sandwiched between the fabric and the other fabric to form a fabric combination.

In one embodiment, one of the surfaces of the fabric has the second fettering hairiness at the end of the irregularly deformed body, and the other surface of the fabric has the fiber loops, so that the fabric has The two surfaces have mutual adhesion functions.

In one embodiment, the fiber loops are selected from air-twisted yarn (ATY), extended false-twisted yarn (DTY) or microfiber isothermal shrinkable yarn.

In one embodiment, the irregular deformation system is formed by hot-melt bonding and aggregation of a plurality of the bead-shaped bodies and/or the column-shaped bodies.

As shown in Figures 1 to 2d, they show a cross-sectional view of the first embodiment of the fabric 1 with a fettering function in this case. The fabric 1 is a woven plain weave, which has a front side 11 and a back side 12 arranged oppositely. And the fabric 1 is woven from warp yarns 2 and/or weft yarns 3. If the warp yarns 2 and the weft yarns 3 are made of thermoplastic long fiber yarns, they must go through a napping process so that the front side 11 of the fabric 1 has a plurality of thermoplastic hairs 5 .

The raising process can be selected from sanding and/or brushing, and if necessary, a shearing process can be performed to make the lengths of the thermoplastic hairs 5 consistent. Furthermore, the thermoplastic long fiber yarn can be selected from extended false twisted yarn (DTY) or air-twisted yarn (ATY) made of polyester, polyolefin or polyamide; it can also be selected from polyester, polyolefin and other materials. Or short fiber yarn made of polyamide and other materials, such as ring spinning, etc., the amount of thermoplastic hairiness 5 of the yarn can be used to determine whether to apply the raising process.

Please refer to Figure 1 again. The back surface 12 has not been subjected to the fluffing process, and therefore does not have the thermoplastic hairiness 5.

The fabric 1 is subjected to a singeing process, so that at least part of the ends of the thermoplastic hairs 5 are melted and condensed into a plurality of first bonded hairs 51 ( Shown in Figure 2b); and then through a hot melting and pressing process, at least a part of the bead-shaped bodies and/or the columnar bodies 511 of the first binding hairs 51 are further heated and melted to form an irregularly deformed body. A plurality of second binding hairs 52 of 521 (shown in Figures 2c and 2d). The bead-shaped body and/or the column-shaped body 511 are heated, melted, pressed and bonded to form the irregularly deformed body 521 with a larger volume. Therefore, the irregular deformation body 521 of the second binding hairs 52 makes the bound fiber loops less likely to slip off, thereby improving the binding function of the fabric 1 to the fiber loops of a loop fabric. Therefore, when the fabric 1 contains water, the second binding hairs 52 have better binding function in a horizontal direction and a vertical direction than the first binding hairs 51 .

A loop fabric 6 (not shown in the drawings according to conventional knowledge) intertwined with the fabric 1 with a fettering function means that at least one surface of the loop fabric has a plurality of fiber loops 61 (shown in Figures 2a to 2d), The fiber loops 61 can come from the yarn itself, such as air-twisted yarn (ATY) that already has dense fiber loops on its surface, extended false-twisted yarn (DTY) with loosely crimped fibers, or two-component crimped elastic yarn (such as INVISTA). T400® fiber), etc.; or microfiber isothermal shrinkage yarn produces loose microfiber loops under the action of heat; or through the weaving method of terry fabric, so as to generate loose yarn loops on the surface of the fabric. Loose yarn loops themselves have loose fiber loops; or woven and knitted fabrics can have loose floating yarns on the surface of these fabrics through fewer interweaving points, and the loose floating yarns themselves will release loose fibers. Loops; or fiber loops laminated by hot melt spinning, electrospinning, etc. can be used as the aforementioned loop fabrics.

Furthermore, the elastic contraction of the elastic yarn can increase the surface density of the fiber loops 61 on the loop fabric, so that the fiber loops 61 have the effect of being looser and highlighting the surface of the loop fabric, for example, with elasticity. The covering yarn with a silk core, or the elastic yarn can be directly woven into the yarn, etc. However, the fiber loops 61 of the aforementioned loop fabric are all well-known techniques and will not be described in detail here.

As shown in Figures 2a, 2b, 2c and 2d, they respectively show the thermoplastic hairiness 5, the first bonding hairiness 51 with the bead and/or the columnar body 511 at the end, and the irregular deformation at the end. An enlarged schematic diagram of the second binding hairs 52 of the body 521 and the fiber loop 61 respectively binding each other. As shown in Figure 2a, through the singeing process, the ends of the thermoplastic hairiness 5 are naturally melted and condensed into the first bonded hairiness 51 (shown in Figure 2b) with the bead-shaped body and/or the columnar body 511. .

Since the fibers used in the fabric 1 are conventional fibers used in general clothes, for example, the single fiber thickness can be selected from 1d/f to 10d/f, but preferably less than 6d/f, and its size is significantly smaller than the hook of the conventional hook and loop fastener. The element uses monofilament with a thickness of approximately 300d/f. The end of the first binding hairs 51 in this embodiment has the bead and/or the columnar body 511, so the binding function of the fiber loop 61 is poor, especially in the vertical direction, so that in some cases In terms of use, for example, the tail end of a bandage is prone to slipping due to poor adhesion, especially when it contains moisture, it loses its binding function.

Subsequently, the first bonding hairiness 51 is further subjected to a hot melt pressing process, so that the bead-shaped body and/or the columnar body 511 are further melt-pressed and deformed to present a second body with an irregular deformation body 521. Tie hairiness 52 (shown in Figure 2c); the irregular deformation body 521 is imprinted by the surrounding tissue texture and fibers of the fabric when the beads and/or the columnar body 511 are in a hot-melt softened state. That is, the second fettered hairiness 52 with the irregular deformation body 521 having different shapes is imprinted in the three-dimensional space with random tissue lines and staggered distribution of fibers.

The hot melt pressing process enlarges the surface area of the original bead-shaped body and/or the columnar body 511 of the first binding hairiness 51, and changes its appearance and direction. That is to say, most of the beads and/or columns 511 of the first bonded hairs 51 are formed along the original direction of the thermoplastic hairs 5 , and the ends of the second bonded hairs 52 are formed along the direction of the original thermoplastic hairs 5 . In addition to being squashed, the irregularly deformed body 521 will also be squeezed and bent by the three-dimensional space in which the aforementioned tissue lines and fibers are staggered. Therefore, the second bonding hairiness 52 will be distributed in a random and disordered manner, which is less chaotic. Due to the specific direction effect, the fiber loops 61 with regularity can be bound, and the fiber loops 61 with disorder can also be bound.

Furthermore, since the irregular deformation body 521 is formed by the bead-shaped body and/or the columnar body 511 being embossed by the surrounding tissue texture and fibers of the fabric 1, in the hot melt pressing process , at least part of the irregular deformation body 521 is formed by hot-melt bonding and aggregation of a plurality of bead-shaped bodies and/or the columnar bodies 511 (shown in Figure 2d), which again expands the volume and volume of the irregular deformation body 521. area, so thicker fibers can be selected as the fiber loops 61 corresponding to the bonds.

The aforementioned hot melt pressing process uses a heating and contact pressure device to soften at least part of the first fettered hairs 51 having the bead-shaped body and/or the columnar body 511, and then compression-mould it to have the irregular shape. The second bonding hairiness 52 of the deformed body 521 . The heating and pressure device can be a similar mechanism of a thermal transfer paper printing machine. The heating and contact pressure device has a heating roller and a pressing circulation belt. The fabric 1 is fed into the heating roller and the pressing circulation belt. In between, a continuous hot melt pressing process is carried out. After the thermal transfer paper printing machine performs the hot melt pressing process, the irregular deformation body 521 has a rough surface.

If a discontinuous hot melt pressing process is selected, the aforementioned heating and contact pressing device is changed to a heating plate and a backing plate, and the fabric 1 is placed between the heating plate and the backing plate for discontinuous pressing. Hot melt pressing. At least one paper can be sandwiched between the fabric 1 and the heating plate to prevent the fabric 1 from being contaminated by the remaining color of the previous fabric; if the thermal transfer printing paper is fed, adjust the appropriate hot melt pressing combination conditions to complete the printing and melting processes at the same time to save costs.

The range of hot melt pressing combination conditions is determined by the fiber material, structure and the type of equipment of the heating and contact pressure device. There are no special restrictions on the temperature, pressure and time that can be selected so as not to destroy the structural characteristics of the fabric, so that at least part of it has The principle is that the first fettered hairiness 51 of the bead and/or the columnar body 511 is compression-molded into the second fettered hairiness 52 with the irregular deformation body 521. For example, the fabric 1 is polyethylene fiber. The hot melt pressing process combination conditions of temperature, pressure and time are much lower than that of polyamide fiber (Polyamide), and the hot melt pressing process combination conditions of polyamide fiber are also slightly lower than polyester fiber (Polyester).

Furthermore, the thickness of the fabric 1 also affects the effect of hot melt pressing, and the hot melt pressing conditions must also be modified according to the structure of the fabric 1. For example, the woven plain fabric 1 of the first embodiment is thinner and thinner than the general terry fabric. It is strong, so the pressure, time and temperature of hot melt pressing in the first embodiment can be less than that of thicker terry fabric. The thermoplastic fiber material of the fabric with fettering function is selected from thermoplastic long fiber yarns such as polyethylene (Polyethylene), polypropylene (Polypropylene), polyamide (Polyamide) or polyester (Polyester), but is not used as limit.

Due to the influence of the surrounding disordered fibers and the imprinting of the tissue texture of the fabric itself, most of the irregular deformations 521 of the second binding hairs 52 are in the shape of irregular sheets that are bent and flattened. Compared with the bead-shaped body and/or the column-shaped body 511 of the first binding hairy 51, the irregular deformation body 521 has a surface area larger than that of the bead-shaped body and/or the column-shaped body 511. It is obvious that Specifically, the fettering function of the irregular deformation body 521 is better than that of the bead-shaped body and/or the columnar body 511, especially the vertical fettering function in a wet state.

The bead-shaped body and/or the columnar body 511 of the first bonding hairiness 51 mainly has a bonding function in the horizontal direction, and the second bonding hairy hair 52 has the irregular deformation body 521, so in addition to having a horizontal direction In addition to the fetter function, it also has the fetter function of the vertical hook.

Furthermore, since the surface area of the irregular deformation body 521 is larger than that of the bead-shaped body and/or the columnar body 511, the fiber loop 61 composed of thicker fibers can be selected, and the thermoplastic long fiber yarn used for the bondage can be selected. The fiber thickness is 3.125d/f, then in addition to finer fibers, the fibers of the fiber loop 61 can also be selected from approximately equal or thicker conventional fibers, which is different from the loops of conventional hook and loop fabrics. The thickness of the loop element must be smaller than the hook element used for fettering, thereby expanding the range of fiber thickness selection for the fiber loop. In particular, the production process of conventional fibers is simpler, more durable and more environmentally friendly than microfibers. For example, microfibers are easily broken down in household washing and discharged into the ocean, and eventually return to our food chain.

Furthermore, the amount of the thermoplastic hairiness 5 determines the amount of the first bonding hairiness 51. For example, the heavier the fluffing process, the more hairiness. The thermoplastic short fiber yarn can also be subjected to a fluffing process to increase the thermoplastic hairiness 5. The number of the second bonded hairiness 52 depends on the number of the first bonded hairiness 51; different fluffing and singeing conditions can produce different sizes of the beads and/or the ends of the first bonded hairiness 51. Or the columnar body 511, and the larger bead-shaped body and/or the columnar body 511 can be hot-melted to form a relatively large irregular deformation body 521. Therefore, the binding function of the fabric 1 with the binding function for the fiber loops 61 can be affected by adjusting the conditions of the raising process, the singeing process and the hot melt pressing process, and the fiber thickness of the fiber loops 61 corresponding to the binding can be selected. . These fluffing and singeing processes are all conventional techniques and will not be described in detail here.

Furthermore, elastic fibers can also be provided in the warp yarns 2 and/or weft yarns 3. The elastic fibers can be selected from covered yarns with a core of polyurethane elastic yarns with a trade name of Lycra, or the aforementioned T400® bicomponent elastic yarns. , making the fabric 1 with fettering function elastic in the warp and/or weft direction, so that the fabric 1 has better pressing function when used as a bandage product.

The irregularly deformed body 521 of the second binding hairs 52 not only has a horizontal binding function, but also has a vertical hooking function. However, when the vertical binding function is too strong, this may sometimes occur. To prevent the second tethering hairs 52 from falling off, a back-adhesive layer can be provided on the back side of the fabric 1 to prevent the second tethering hairs 52 from falling off. Among them, setting up the adhesive layer is a common skill and will not be described in detail here.

As shown in Figure 3, it shows a cross-sectional view of the second embodiment of the fabric with fettering function in this case. In this embodiment, the fabric 1 is a weft knitted single jersey or a warp knitted plain weave (tricot). An object has a front side 11 and a back side 12. The fabric 1 is woven from thermoplastic long fiber yarn containing polyester, polyolefin or polyamide, etc., and the yarn count is an extended false twist yarn with a thickness of 75d/36f, 150d/36f or 150d/48f, or Containing elastic fiber makes the fabric 1 elastic in the warp and/or weft direction. The elastic fiber can be selected from the covered yarn with polyurethane elastic yarn as the core to prevent the elastic fiber from being broken during sanding.

The front surface 11 of the fabric 1 has a plurality of thermoplastic hairs 5 through a sanding and/or brushing process. Then, through a singeing process, at least part of the ends of the thermoplastic hairs 5 are melted and condensed into a plurality of first bonded hairs 51 having a bead and/or a column 511 . Finally, through a hot melt pressing process, at least part of the bead-shaped body and/or the columnar body 511 is embossed into a plurality of second bonding hairs 52 having an irregular deformation body 521, so that the irregular deformation body 521 It can produce a bonding function with a plurality of fiber loops 61.

If necessary, the fabric 1 can be attached to a suitable loop fabric as mentioned above, so that the front and back sides have the function of binding each other.

As shown in Figure 4, it shows a cross-sectional view of the third embodiment of the fabric with fettering function in this case. In this embodiment, the fabric 1 is a circular knitted single-sided terry knitted fabric, which has a front side 11 and a back side 12 , the front side 11 has a plurality of loops. The fabric 1 is made of thermoplastic long fiber yarns made of polyester, polyolefin or polyamide. The thermoplastic long fiber yarns can be selected from polyester or nylon materials such as 75d/36f, 150d/36f or 150d/48f. Thermoplastic long fibers, such as extended false-twisted yarn, undergo a shearing process to remove the loop tops, so that the front side 11 of the fabric 1 has a plurality of standing thermoplastic hairs 5 . Then, through a singeing process, at least part of the ends of the thermoplastic hairs 5 are melted and condensed into a plurality of first bonded hairs 51 having a bead and/or a column 511 . Finally, through a hot melt pressing process, at least a part of the bead-shaped body and/or the columnar body 511 is embossed into a plurality of second bonding hairs 52 having an irregular deformation body 521, so that the irregular deformation body 521 can produce a bonding function with multiple fiber loops 61.

Furthermore, by changing the weaving density, the amount of thermoplastic hairiness 5 can be changed, and the bonding force of the fetters can be adjusted to provide products with different bonding forces. If necessary, elastic fibers can be provided in the structure of the fabric 1 to make the fabric 1 elastic and soft, and at the same time, the fabric 1 has better conformability, and the conformability further improves the fettering function. Since the irregular deformation body 521 can greatly increase the bonding strength, and the bonding strength sometimes causes the second bonding hairiness 52 to be pulled off by the fiber loop 61, the single-sided terry fabric 1 can be added with an adhesive backing. The process is to adhere the second bonding hairiness 52. Alternatively, a reverse wrapping method can be selected, that is, the terry yarn is covered by the ground tissue yarn, which can improve the problem of the second fetter hairiness 52 falling off.

As shown in Figure 5, it shows a cross-sectional view of the fourth embodiment of the fabric with fettering function in this case. In this embodiment, the fabric 1 is a woven fabric, which has a front side 11 and a back side 12. This embodiment expands In order to limit the use range of the fabric 1, when the front side 11 and the back side 12 come into contact, they have the function of binding each other. In this embodiment, at least part of a warp yarn 2 and a weft yarn 3 are made of thermoplastic long fiber yarns such as polyamide or polyester, for example, an elastic core-spun warp yarn 2a and an elastic core-spun yarn coated with polyurethane elastic fibers. The weft yarn 3a makes the fabric 1 elastic in both the warp and weft directions.

The warp yarns 2 and the weft yarns 3 in this embodiment can all use elastic core-spun warp yarns 2a and elastic core-spun weft yarns 3a, or partially use elastic core-spun warp yarns 2a and elastic core-spun weft yarns 3a according to the elasticity requirements. The elastic core-spun warp yarn 2a and the elastic core-spun weft yarn 3a are woven in a stretched state. After the gray cloth is off the machine, the elastic core-spun warp yarn 2a and the elastic core-spun weft yarn 3a go through a pre-setting process before dyeing and finishing. First release the residual stress generated by the elastic core-spun warp yarn 2a and the elastic core-spun weft yarn 3a during the weaving process, and then restore the elasticity of the elastic core-spun warp yarn 2a and the elastic core-spun weft yarn 3a, so that the fully shrunk The fabric 1 can be stretched and shaped again to obtain the required length and width, so that the fabric 1 has elasticity in the warp and/or weft direction to overcome the curling problem of longitudinal deformation when cutting into long strips. This makes the fabric 1 the best material for bandages and other uses.

In this embodiment, the front surface 11 of the fabric 1 is a warp surface, and the reverse surface 12 is a weft surface. The fabric 1 is basically woven from the elastic core-spun warp yarn 2a and the elastic core-spun weft yarn 3a, so that The fabric 1 is elastic in both the warp and weft directions, and the front side 11 undergoes a sanding and/or brushing process, so that the front side 11 of the fabric 1 has a plurality of thermoplastic hairs 5 . Then, through a singeing process, at least part of the ends of the thermoplastic hairs 5 are melted and condensed into a plurality of first bonded hairs 51 having a bead and/or a column 511 . Finally, through a hot melt pressing process, at least part of the beads and/or columns 511 with smooth surfaces are embossed into a plurality of second binding hairs 52 having an irregular deformation body 521 .

In addition to the elastic core-spun weft yarn 3a, the weft yarn surface also has a plurality of weft yarns 3b of fluffy fiber loops 61. The weft yarns 3b of the fluffy fiber loops 61 can be selected from polyester, polyamide, etc. Conventional fibers such as air-twisted yarn, bicomponent crimped elastic yarn or extended false-twisted yarn, because ultrafine fibers, such as those with a single fiber less than 0.25D, are not as heat-resistant as conventional fibers, so using conventional fibers can avoid the need for heat-melting Melted felt knots occur during pressing to prevent the fiber loops 61 from losing bulk.

Due to the bulkiness of the weft yarn 3b, the elastic core-spun weft yarn 3a on the reverse side 12 is basically covered or shielded by the weft yarn 3b of the fluffy fiber loops 61. Its function is that the elastic core-spun weft yarn 3a is elastic. After shrinkage, the bulkiness of the fiber loops 61 of the weft yarn 3b is increased, and the bead-shaped body and/or the columnar body 511 of the first bonding hairiness 51 and the second bonding hairiness 52 are improved. The bonding function of the irregularly deformed body 521. The weft yarns 3b of the bulky fiber loops 61 appear at intervals, for example, once every three weft yarns, and with fewer interlacing points, the weft yarns 3b of the bulky fiber loops 61 have a longer span, and Appearing in the form of floating yarns, for example, there is only one interweaving point across five warp yarns. Through this relaxed interweaving, the bulkiness of the weft yarns 3b of the fluffy fiber loops 61 can be improved, thereby improving the front side 11 and the back side. 12 mutual bonding function.

Therefore, the fabric 1 of this embodiment itself has the function of binding the front side and the back side to each other, in which the first binding hairiness 51 provides a horizontal binding function, and the second binding hairiness 52 provides both a horizontal and a horizontal binding function. The vertical fettering function can greatly reduce the thickness of the fabric 1 and overcome the problem that conventional pressure-sensitive adhesive bandages are not sticky when wet.

Furthermore, as long as the two yarns can be roughly displayed on the front and back of the fabric 1, the fabric 1 can be used as a fabric with front and back mutually bonded fabrics. For example, twill and satin weaves can also make the warp and weft yarns separate. The function that appears on the different side is a common technique and will not be described in detail here.

As shown in Figure 6, it shows a cross-sectional view of the fifth embodiment of the fabric with fettering function in this case. In this embodiment, the fabric 1 is a double-sided terry woven, circular knitted or warp knitted fabric, and the fabric 1 has A front side 11 and a back side 12, this embodiment is a further application of the third embodiment, so that the front side 11 and the back side 12 have the function of binding each other after contact. Both sides of the fabric 1 have a plurality of loops, which are made of thermoplastic long fiber yarns made of polyester, polyolefin or polyamide materials. The thermoplastic long fiber yarns are selected from 75d/36f, 150d/36f or 150d. /48f and other thermoplastic long fibers made of polyester or polyamide, such as extended false-twisted yarn, thermoplastic long fiber air-twisted yarn, etc.

During production, the front side 11 of the fabric 1 is an extended false-twisted yarn, and the top of the loop is removed through a shearing process, so that the front side 11 of the fabric 1 has a plurality of standing thermoplastic hairs 5 . Then, through a singeing process, at least part of the ends of the thermoplastic hairs 5 are melted and condensed into a plurality of first bonded hairs 51 having a bead and/or a column 511 . Finally, through a hot melt pressing process, at least part of the bead-shaped body and/or the columnar body 511 is embossed into a plurality of second bonding hairs 52 having an irregular deformation body 521, so that the irregular deformation body 521 It can produce a bonding function with a plurality of fiber loops 61.

In this embodiment, the loops on the reverse side 12 of the fabric 1 are selected from air-twisted yarns or extended false-twisted yarns; and elastic fibers are added to the ground weave yarns of the fabric 1. Through the elastic fibers The rebound makes the air-twisted yarn more fluffy, so as to increase the coverage area of the fiber loops 61 formed on the back side 12 of the fabric 1, thereby improving the mutual binding function of the front side 11 and the back side 12.

As mentioned above, the irregular deformation body 521 of the second bonding hairiness 52 has a larger surface area than the thermoplastic hairiness 5 , so fibers with a thickness similar to those used in the front surface 11 can be used as the fiber loop 61 , such as 50d/144f, 75d/36f, 150d/36f or 150d/48f, etc.

As shown in Figure 7, it shows a cross-sectional view of the sixth embodiment of the fabric with fettering function in this case. In this embodiment, the fabric 1 is a knitted double-sided fabric, such as PK bird-eye fabric (Bird-eye pique fabric). ). The PK bird's eye cloth can roughly display the yarn used to generate the thermoplastic hairiness 5 and the yarn used for the fiber loop 61 on a front side 11 and a back side 12 respectively. The front side 11 of the fabric 1 is made of thermoplastic long fiber yarns containing polyester, polyolefin or polyamide materials. The thermoplastic long fiber yarns are selected from extended false twisted yarns, etc. As shown in the previous embodiments, the fabric 1. Through a hair raising process, the front surface 11 of the fabric 1 is formed with a plurality of thermoplastic hairs 5. Then, through a singeing process, at least part of the ends of the thermoplastic hairs 5 are melted and condensed into a plurality of first bonded hairs 51 having a bead and/or a column 511 . Finally, through a hot melt pressing process, at least part of the bead-shaped body and/or the columnar body 511 is embossed into a plurality of second bonding hairs 52 having an irregular deformation body 521, so that the irregular deformation body 521 It can produce a bonding function with a plurality of fiber loops 61.

The reverse side 12 of the fabric 1 is made of a plurality of fiber loops 61 formed by air-twisted yarn containing elastic fibers or isothermal shrinkable yarn such as 80d/156f, but is not limited to this. As shown in the previous embodiment, the fiber loops 61 are made more relaxed and fluffy by the tension of the elastic fibers during weaving and the shrinkage after the tension is eliminated after dyeing and finishing, thereby making the fabric of this embodiment 1. It has the function of binding the front and back sides to each other.

As shown in Figure 8, it shows a cross-sectional view of the seventh embodiment of the fabric with fettering function in this case. In this embodiment, the fabric 1 is a knitted three-dimensional double-sided fabric (spacer), which can float two kinds of yarns respectively. There is now a front side 11 and a back side 12 of the fabric 1, so the fabric 1 has a connecting yarn 8 that can be connected between the front side 11 and the back side 12. The yarn appearing on the front 11 can be selected from thermoplastic long fiber yarns made of polyester or polyamide such as 150d/48f, 150d/36f, etc., such as extended false twisted yarn, and the thermoplastic long fiber yarn can be set to an appropriate ratio. of elastic fiber, making it elastic.

As shown in the previous embodiment, the fabric 1 undergoes a hair raising process to form a plurality of thermoplastic hairs 5 on the front side 11 of the fabric 1 . Then, through a singeing process, at least part of the ends of the thermoplastic hairs 5 are melted and condensed into a plurality of first bonded hairs 51 having a bead and/or a column 511 . Finally, through a hot melt pressing process, at least part of the bead-shaped body and/or the column-shaped body 511 is embossed into a plurality of second binding hairs 52 having an irregular deformation body 521 .

The reverse side 12 has a plurality of fiber loops 61. The yarns used for the fiber loops 61 can be selected from polyester or polyamide materials, air-twisted yarns containing elastic fibers or extended pseudo-bonded yarns, etc., but are not made of polyester or polyamide materials. This is the limit. As shown in the previous embodiment, the fiber loops 61 of the reverse side 12 are composed of air-twisted yarn, for example, air-twisted yarn covered with elastic fiber, and by the tension and tension of the elastic fiber during weaving, The shrinkage after the tension is eliminated after dyeing and finishing makes the surface fiber loops of the air-twisted yarn more relaxed and fluffy, so as to loosen the dense fiber loops 61. The front side 11 and the back side 12 of the fabric 1 have mutual binding functions and overcome the problem that conventional pressure-sensitive adhesive bandages are not sticky when wet.

Furthermore, in this embodiment, the more intertwining points the connecting yarn 8 of the three-dimensional double-sided fabric 1 has with the front side 11 and the back side 12 , the more it can reduce the problem of fiber scattering on the cutting edge of the fabric 1 . The connecting yarn 8 can be selected from a thicker monofilament to increase the support of the three-dimensional double-sided fabric 1 in the thickness direction, or a general thermoplastic long fiber yarn can be selected to reduce the thickness of the three-dimensional double-sided fabric, or elasticity can be used. The fibers make the three-dimensional double-sided fabric 1 elastic in the warp and weft directions.

In addition, the double-sided three-dimensional fabric 1 can be cut directly using scissors and other cutting tools without the need for melting and cutting methods such as ultrasonic cutting machines or laser cutting machines, and the cutting edge is soft and free of thick and hard sintered particles caused by melting and cutting, making it easy to use. The user can cut the length and shape according to the required length, and the flexibility in the warp and weft directions greatly improves the convenience of using the product. At the same time, it can overcome the curling problem of longitudinal deformation when cutting long strips, so as to facilitate the bandage. Convenience makes it the best material for bandages.

As shown in Figure 9, it shows a cross-sectional view of the seventh embodiment of the fabric with fettering function in this case. In this embodiment, the fabric 1 and a loop fabric 6 are sandwiched with an elastic body 9 under the overfeed condition. The body 9 can be selected from polymer breathable waterproof membrane, polymer breathable waterproof membrane, Neoprene (chloroprene rubber) or elastic fabric, etc. to form a fabric combination 10. When the fabric combination is used as a bandage, it can increase the durability of the bandage. The elasticity is used to overcome the longitudinal hemming problem of conventional knitted hoop fabrics, so that it can be used for bandaging that requires pressure, such as for banding varicose veins.

Furthermore, the thermoplastic long fiber yarn and the thermoplastic short fiber yarn selected in the aforementioned embodiments may have a plurality of hollow inner cavities and/or a plurality of micropores on the surface to expand the surface area, so that the fabric 1 It has moisture absorption and quick-drying functions. At the same time, the fabric can be further hygienic processed or interwoven with silver-plated, zinc-plated or graphene-plated fibers to make the fabric 1 have antibacterial functions. In addition, the thermoplastic long fiber yarn is further combined with metal fibers, such as silver-plated fibers, copper fibers or graphene-containing fibers, to have antistatic and conductive functions.

In addition to the aforementioned thermal transfer paper printing machine, the heating and pressure device can also choose a similar mechanism such as a heat calender or a heat press laminating machine. The heating and contact pressure device has at least one heating pressure wheel set. , feeding the fabric 1 to the heated press wheel set for a continuous hot melt pressing process, so that at least a part of the first bonding hairiness 51 having the beads and/or the columnar bodies 511 is softened. Due to the The isobaric wheel set has a surface such as metal or silicone, so each of the second bonding hairs 52 will be compression molded into an irregular deformation body 521 with a rough or bright surface.

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

(1) The ends of the second binding hairs of the fabric each have an irregular deformation body, which not only has a horizontal binding function, but also a vertical binding function; if the fabric is used as a bandage , the end of the bandage will be firmly attached and not easy to loosen.

(2) The ends of the second fetter hairs of the fabric each have the irregular deformation body and can have a fetter function in a humid environment.

(3) The fabric’s constituent fibers are the same as those of ordinary clothing fabrics. Therefore, in addition to being a cloth, it also has horizontal and vertical binding functions. Therefore, the softness of the fabric can be directly used as clothing and bandages. , wrap or buckle to use.

(4) The fabric can be made into a fabric with mutual bonding functions on the front and back. It is woven like cloth, and its shape can be printed, dyed and cut at will. It also has a comprehensive binding function; when used as a wrap or bandage, it can be bonded at will. The use of hook-and-loop fasteners has infinite uses, and it can be called a breakthrough in hook-and-loop fasteners.
