[0001] The application relates to the technical field of textile fabrics, in particular to a brocade spandex texture fabric. BACKGROUND

[0002] The brocade spandex texture fabric is a fabric with special texture and good elasticity. The brocade spandex texture fabric is usually blended from nylon and spandex. The nylon has high strength and wear resistance, and the spandex provides good elasticity and comfort. The blended fabric combines the advantages of both, so that the fabric has good elasticity and durability.

[0003] However, when there is a high requirement for the warmth retention performance of the fabric, the existing brocade spandex texture fabric cannot meet the requirement. CONTENT OF THE UTILITY MODEL

[0004] In order to further improve the warmth retention performance of the brocade spandex texture fabric, the application provides a brocade spandex texture fabric.

[0005] The application provides a brocade spandex texture fabric, which adopts the following technical scheme:

[0006] The brocade spandex texture fabric comprises a base cloth layer and a polyurethane adhesive layer. The yarn of the base cloth layer is blended from nylon and spandex. The base cloth layer is provided with two layers. The polyurethane adhesive layer is arranged between the two base cloth layers, and is used for adhesively fixing the two base cloth layers.

[0007] By adopting the above technical scheme, on the one hand, the base cloth layers on both sides of the polyurethane adhesive layer make the outer periphery of the fabric have a brocade spandex texture; and the polyurethane adhesive layer has windproof and heat insulation effects, so that the warmth retention effect of the fabric can be improved.

[0008] Optionally, the base cloth layer is provided with a plush layer on the side away from the polyurethane adhesive layer.

[0009] By adopting the above technical scheme, the plush layer is arranged on the base cloth layer through a process, so as to further improve the warmth retention performance of the fabric and further improve the comfort of the wearer.

[0010] Optionally, the height of the plush of the plush layer is 0.2-0.5 mm.

[0011] By adopting the above technical scheme, the height of the plush is 0.2-0.5 mm, so that the height of the plush is relatively short, the direction of the plush is reduced, and the texture effect of the brocade spandex texture of the fabric is further improved.

[0012] Optionally, the polyurethane adhesive layer is provided with a plurality of second communication holes.

[0013] By adopting the technical scheme, the polyurethane adhesive layer is provided with a plurality of second communication holes, so that water vapor of the first base cloth layer can be sequentially discharged to the outside through the polyurethane adhesive layer and the second base cloth layer, thereby improving the dry comfort of the fabric.

[0014] Optionally, the yarn of the base cloth layer further comprises a polypropylene fiber, and the polyamide and the spandex are arranged on the periphery of the polypropylene fiber.

[0015] By adopting the technical scheme, the water-repellent effect of the polypropylene fiber is utilized, so that when the yarn of the base cloth layer absorbs the sweat of the wearer, the sweat in the yarn can be distributed on the outer peripheral surface of the yarn, thereby facilitating the air drying of the sweat on the fabric and further improving the dry comfort of the wearer.

[0016] Optionally, the polyurethane adhesive layer is a polyurethane-acrylic copolymer adhesive layer.

[0017] By adopting the technical scheme, the polyurethane-acrylic copolymer is a shape memory material, when the temperature is lower than Tg (glass transition temperature), the polyurethane adhesive layer shrinks, and the pores of the polyurethane adhesive layer become smaller, thereby improving the windproof and warm-keeping performance of the fabric; when the temperature is higher than Tg (glass transition temperature), the polyurethane adhesive layer returns to the original state, and the pores of the polyurethane adhesive layer return to larger pores, thereby improving the air permeability of the fabric.

[0018] Optionally, the two base cloth layers are respectively named as a first base cloth layer and a second base cloth layer, the first base cloth layer is a skin-friendly layer, the first base cloth layer adopts a jacquard process to form a honeycomb grid structure, and a plurality of first meshes are arranged at intervals in the first base cloth layer.

[0019] By adopting the technical scheme, the first base cloth layer has a honeycomb grid structure, so that the plush in the first mesh can fully absorb water vapor and exchange heat in the first mesh, thereby improving the comfort of the fabric.

[0020] Optionally, the yarn of the first base cloth layer further comprises a cotton fiber, and the cotton fiber is blended with the polyamide and the spandex to form the yarn of the first base cloth layer.

[0021] By adopting the technical scheme, the cotton fiber is blended in the first base cloth layer to improve the skin-friendly performance of the first base cloth layer.

[0022] In summary, the present application has at least one of the following beneficial technical effects:

On the one hand, the base cloth layers on both sides of the polyurethane adhesive layer make the outer peripheral surface of the fabric have a polyamide-spandex texture pattern, and the polyurethane adhesive layer has a windproof and heat-insulating effect, thereby improving the warm-keeping effect of the fabric.

[0024] 2. The height of the plush is 0.2-0.5mm, the height of the plush is shorter, thereby reducing the reverse range of the plush, and further improving the texture effect of the jacquard texture of the fabric;

[0025] 3. The polyurethane-acrylic copolymer is a shape memory material. When the temperature is lower than Tg (glass transition temperature), the polyurethane adhesive layer shrinks, and the pores of the polyurethane adhesive layer become smaller, thereby improving the windproof and warm-keeping performance of the fabric; when the temperature is higher than Tg (glass transition temperature), the polyurethane adhesive layer restores to the original state, and the pores of the polyurethane adhesive layer recover to larger pores, thereby improving the air permeability of the fabric.

DETAILED DESCRIPTION

[0033] The following will be further described in detail in combination with the accompanying Figure 1 6 to further illustrate the present application.

[0034] The embodiment of the present application discloses a jacquard texture fabric. Referring to Figure 1 , the jacquard texture fabric includes a base cloth layer 1 and a polyurethane adhesive layer 2; the base cloth layer 1 is provided with two layers, and the polyurethane adhesive layer 2 is arranged between the two layers of the base cloth layer 1, and the polyurethane adhesive layer 2 is used for bonding and fixing the two layers of the base cloth layer 1.

[0035] Referring to Figure 1In the production process of the brocade and spandex texture fabric, the two base cloth layers 1 are bonded by using solvent type polyurethane glue, and the solvent type polyurethane glue is hardened to form a polyurethane bonding layer 2, so that the two base cloth layers 1 are combined into a whole.

[0036] Referring to Figure 2 and Figure 3 In this embodiment, the base cloth layer 1 is composed of a mixture of nylon 13 and spandex 14, so that the fabric has a brocade and spandex texture. The two base cloth layers 1 are respectively named as the first base cloth layer 11 and the second base cloth layer 12, and the first base cloth layer 11 is a skin-friendly layer. Referring to Figure 2 In this embodiment, the first base cloth layer 11 is woven by the first yarn 111, and the first yarn 111 is composed of a mixture of cotton fiber 15, nylon 13 and spandex 14, so as to improve the skin-friendly performance of the first base cloth layer 11. Referring to Figure 3 The second base cloth layer 12 is woven by the second yarn 121, and the second yarn 121 is composed of a mixture of nylon 13 and spandex 14, so that the outer periphery of the fabric has a clear brocade and spandex texture.

[0037] The implementation principle of the brocade and spandex texture fabric according to the embodiment of the application is as follows:

[0038] Referring to Figure 1 On the one hand, the base cloth layers 1 on both sides of the polyurethane bonding layer 2 make the outer periphery of the fabric have a brocade and spandex texture, and the polyurethane bonding layer 2 has a windproof and heat insulation effect, so as to improve the warmth-keeping effect of the fabric.

[0039] Embodiment 2

[0040] The difference between this embodiment 2 and the embodiment 1 is as follows:

[0041] Referring to Figure 4 The base cloth layer 1 is provided with a plush layer 3 on the side away from the polyurethane bonding layer 2, so as to further improve the warmth-keeping performance of the fabric and further improve the comfort of the wearer. The plush layer 3 can be realized by weaving, specifically as follows: first, weaving a front comb organization on one side of the base cloth layer 1, and the front comb organization is knitted by using short extension lines; then, the front comb organization is broken by using a pulling process, so that the short extension lines form the plush of the plush layer 3.

[0042] In this embodiment, the height of the plush of the plush layer 3 is 0.2-0.5mm, and the height of the plush is relatively short, so as to reduce the reverse range of the plush and further improve the display effect of the brocade and spandex texture of the fabric.

[0043] Referring to Figure 4In the embodiment, the first base cloth layer 11 adopts a jacquard process to form a honeycomb grid structure, and the first base cloth layer 11 is provided with a plurality of first meshes 112 at intervals. The first base cloth layer 11 is a honeycomb grid structure, so that the plush in the first mesh 112 can fully absorb water vapor and exchange heat in the first mesh 112, so as to improve the comfort of the fabric.

[0044] Embodiment 3

[0045] The difference between the embodiment 3 and the embodiment 2 is that:

[0046] Referring to Figure 5 , the polyurethane adhesive layer 2 is provided with a plurality of second communication holes 21; that is, the two base cloth layers 1 are bonded by using solvent type polyurethane adhesive, and the partial area of the base cloth layer 1 is not bonded and fixed by using the solvent type polyurethane adhesive, so as to form the second communication hole 21.

[0047] The implementation principle of the embodiment of the satin-nylon textured fabric is:

[0048] Referring to Figure 5 , the polyurethane adhesive layer 2 is provided with a plurality of second communication holes 21, so that the water vapor of the first base cloth layer 11 can be discharged to the outside in turn through the polyurethane adhesive layer 2 and the second base cloth layer 12, so as to improve the dry comfort of the fabric.

[0049] Referring to Figure 6 , in the embodiment, the yarn of the base cloth layer 1 further includes the polypropylene 16, and the nylon 13 and the spandex 14 are arranged on the outer periphery of the polypropylene 16. The embodiment takes the first yarn 111 as an example for display.

[0050] By using the water-repellent effect of the polypropylene 16, when the yarn of the base cloth layer 1 absorbs the sweat of the wearer, the sweat in the yarn can be distributed on the outer peripheral surface of the yarn; thereby being beneficial to the air drying of the sweat on the fabric, and further improving the dry comfort of the wearer.

[0051] Embodiment 4

[0052] The difference between the embodiment 4 and the embodiment 3 is that:

[0053] The polyurethane adhesive layer 2 is a polyurethane-acrylic copolymer adhesive layer.

[0054] The polyurethane-acrylic copolymer is a shape memory material. When the temperature is lower than Tg (glass transition temperature), the polyurethane adhesive layer 2 shrinks, and the porosity of the polyurethane adhesive layer 2 becomes small, so as to improve the windproof and warm-keeping performance of the fabric; when the temperature is higher than Tg (glass transition temperature), the polyurethane adhesive layer 2 restores to the original state, and the porosity of the polyurethane adhesive layer 2 restores to a larger porosity, so as to improve the air permeability of the fabric.

[0055] In the present embodiment, the material used for the polyurethane adhesive layer 2 is a polyurethane-acrylic copolymer (Tg=25°C). When the outside temperature is lower than 25°C, the porosity of the polyurethane adhesive layer 2 becomes smaller, thereby improving the windproof and warm-keeping performance of the fabric. When the outside temperature is higher than 25°C, the porosity of the polyurethane adhesive layer 2 returns to a larger porosity, thereby improving the air permeability of the fabric.

[0056] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Any equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
