TECHNICAL FIELD

[0001] The application relates to the technical field of textiles, in particular to an elastic jean-textured fabric. BACKGROUND

[0002] The jean-textured fabric is a fabric with a jean-textured pattern, and the jean-textured fabric can be divided into various patterns such as plain weave, twill weave, herringbone weave and interwoven weave; among them, the twill jean is the most common one.

[0003] In the production process of the jean-textured fabric, pure cotton fibers are usually used to weave the jean-textured fabric; and elastic fibers such as spandex can be added to improve the elasticity of the jean-textured fabric. However, in the folding storage of the jean-textured fabric, the yarns in the jean-textured fabric will generate different stresses due to physical extrusion, so as to cause the jean-textured fabric to generate wrinkles and creases, and affect the appearance of the fabric. CONTENT OF THE INVENTION

[0004] In the use process of the jean-textured fabric, in order to reduce the wrinkles and creases of the jean-textured fabric, the application provides an elastic jean-textured fabric.

[0005] The application provides an elastic jean-textured fabric, which adopts the following technical scheme:

[0006] The elastic jean-textured fabric comprises interwoven warp and weft, the warp comprises alternately arranged first warp and second warp, the first warp is polyamide, the second warp is core-spun yarn, the second warp comprises a memory cotton fiber yarn core and a cotton fiber wrapping layer, and the cotton fiber wrapping layer wraps the outer periphery of the memory cotton fiber yarn core.

[0007] By adopting the above technical scheme, the warp and weft are interwoven in a three-over-one-under twill manner, so that the fabric has a twill effect of jean-textured pattern; at the same time, the warp on the front of the fabric is more, and the weft on the back of the fabric is more.

[0008] The polyamide has the characteristics of high strength and wear resistance, so that the first warp has the effects of being tough and straight, and having good wrinkle resistance; the first warp is arranged on the front of the fabric, and can improve the wear resistance of the fabric; and after the jean-textured fabric is subjected to stress, the first warp also makes the jean-textured fabric return to the original flat state, reduces the wrinkles and creases of the jean-textured fabric, and improves the appearance of the jean-textured fabric clothes.

[0009] The memory cotton fiber is a high polymer material generated by the reaction of a hydroxyl-containing compound such as polyester and polyether with isocyanate. The memory cotton fiber has a unique molecular structure and can slowly restore the original state after being subjected to pressure, so that the second warp has good resilience. When the jeans fabric clothes are folded and unfolded, the second warp provides resilience, so that the jeans fabric clothes are unfolded, further reducing the wrinkles and creases of the jeans fabric, and improving the aesthetics of the jeans fabric clothes.

[0010] In summary, after the folding external force of the jeans fabric disappears, the cooperation of the first warp and the second warp can reduce the wrinkles and creases of the jeans fabric, improve the flatness of the jeans fabric, and improve the aesthetics of the jeans fabric clothes.

[0011] Optionally, the warp further includes a third warp, and the third warp is a pure cotton yarn.

[0012] By adopting the above technical solution, the third warp is a pure cotton yarn, so that the jeans fabric has good moisture absorption and air permeability.

[0013] Optionally, the third warp is arranged between the first warp and the second warp.

[0014] By adopting the above technical solution, the water absorption and air permeability of the first warp and the second warp are poor. By arranging the third warp between the first warp and the second warp, the water absorption and air permeability of the third warp are utilized to improve the air permeability and sweat-releasing performance of the jeans fabric.

[0015] Optionally, the diameter of the third warp is greater than the diameter of the first warp and the diameter of the third warp.

[0016] By adopting the above technical solution, the diameter of the third warp is greater than the diameter of the first warp and the diameter of the third warp, further improving the moisture absorption and sweat-releasing performance of the jeans fabric.

[0017] Optionally, the weft includes first weft and second weft arranged side by side, the first weft is spandex, and the second weft is core-spun yarn, the second weft includes a polyester yarn core and an acetate fiber layer, and the acetate fiber layer is wrapped around the outer periphery of the polyester yarn core.

[0018] By adopting the technical scheme, the spandex has good elasticity, so that the jean pattern fabric has good elasticity. The acetate fiber layer is composed of acetate fibers, and the acetate fibers have good hydrophilicity. In the jean pattern fabric, the back of the jean pattern fabric has more weft lines, and the polyester core of the second weft line has poor moisture absorption, and the acetate fiber layer has good moisture absorption, so that when the second weft line absorbs sweat stains, the sweat stains are adsorbed on the outer circumferential surface of the second weft line, so as to transmit the sweat stains to the warp. Therefore, the jean pattern fabric has good sweat absorption and sweat discharge performance, and improves the comfort of the wearer.

[0019] Optionally, the polyester core is a hollow polyester, and the polyester yarn has a hollow chamber along the axial direction of the polyester core.

[0020] By adopting the technical scheme, the polyester core has a hollow chamber inside, and the hollow chamber can be used to store air, so as to improve the warmth retention performance of the second weft line. The hollow chamber of the polyester yarn can be used for air circulation, so as to improve the air permeability of the jean pattern fabric.

[0021] Optionally, the cross section of the hollow chamber has a concave area along the cross section of the polyester core.

[0022] By adopting the technical scheme, the cross section of the hollow chamber has a concave area, so that when the polyester core is deformed under pressure, the deformation of the hollow chamber of the polyester yarn is facilitated, so as to facilitate the circulation of air in the hollow chamber, and improve the moisture absorption and air permeability of the jean pattern fabric.

[0023] Optionally, the cross section of the hollow chamber has two concave areas.

[0024] By adopting the technical scheme, the two concave areas arranged at intervals facilitate the deformation of the polyester yarn.

[0025] In summary, the present application has at least one of the following beneficial technical effects:

[0026] 1. After the jean pattern fabric is folded and the external force disappears, the cooperation of the first warp and the second warp can reduce the wrinkles and creases of the jean pattern fabric, improve the flatness of the jean pattern fabric, and improve the appearance of the jean pattern fabric clothes.

[0027] 2. Since the polyester core has a hollow chamber inside, the hollow chamber can be used to store air, so as to improve the warmth retention performance of the second weft line. The hollow chamber of the polyester yarn can be used for air circulation, so as to improve the air permeability of the jean pattern fabric.

[0028] 3. The cross section of the hollow chamber has a concave area, so that when the polyester yarn core is deformed under pressure, the deformation of the polyester yarn hollow chamber is facilitated, the circulation of air in the hollow chamber is facilitated, and the moisture absorption and air permeability of the denim fabric is improved.

DETAILED DESCRIPTION

[0033] The following will be described in detail in combination with the accompanying Figure 1 -3 of the present application.

[0034] The embodiment of the present application discloses a stretch denim fabric. Referring to Figure 1 , the stretch denim fabric comprises interwoven warps 1 and wefts 2; the warps 1 are vertically arranged, and the wefts 2 are horizontally arranged. The warps 1 and the wefts 2 are twill interwoven in a three-over-one-under manner, so that the fabric has a twill effect of denim; the warps 1 on the front of the fabric are more organized, and the wefts 2 on the back of the fabric are more organized.

[0035] Referring to Figure 1 , the warps 1 comprise side-by-side arranged first warps 11, second warps 12 and third warps 13, the third warps 13 are arranged between the first warps 11 and the second warps 12, and the first warps 11, the second warps 12 and the third warps 13 are mainly arranged on the front of the denim fabric.

[0036] Referring to Figure 1 , the first warps 11 are nylon, the nylon has the characteristics of high strength and wear resistance, so that the first warps 11 have the effects of being tough and straight, and having good wrinkle resistance. After the folding stress of the denim fabric disappears, the first warps 11 also make the denim fabric return to the original flat state, reduce the wrinkles and creases of the denim fabric, and improve the appearance of the denim fabric clothes.

[0037] Referring to Figure 1 and Figure 2, the second warp yarn 12 includes a memory cotton fiber yarn core 121 and a cotton fiber wrapping layer 122 wrapped on the outer periphery of the memory cotton fiber yarn core 121. The memory cotton fiber is a high polymer material generated by the reaction of a hydroxyl-containing compound such as polyester and polyether with isocyanate, which has a unique molecular structure and can slowly restore to the original state after being subjected to pressure, so that the second warp yarn 12 has good resilience. Thus, when the clothes of the denim pattern fabric are unfolded after folding, the second warp yarn 12 will provide resilience, so that the denim pattern fabric is unfolded and flattened, further reducing the wrinkles and creases of the denim fabric and improving the appearance of the clothes of the denim pattern fabric.

[0038] With reference to Figure 1 , the third warp yarn 13 is a pure cotton yarn, which has good moisture absorption and air permeability. Since the water absorption and air permeability of the first warp yarn 11 and the second warp yarn 12 are poor, the third warp yarn 13 is arranged between the first warp yarn 11 and the second warp yarn 12 to improve the air permeability and sweat-releasing performance of the denim pattern fabric by using the water absorption and air permeability of the third warp yarn 13. In this embodiment, the diameter of the third warp yarn 13 is greater than the diameter of the first warp yarn 11, which further improves the moisture absorption and sweat-releasing performance of the denim pattern fabric.

[0039] In summary, after the folding external force of the denim pattern fabric disappears, the cooperation of the first warp yarn 11 and the second warp yarn 12 can reduce the wrinkles and creases of the denim pattern fabric, improve the flatness of the denim pattern fabric, and improve the appearance of the clothes of the denim pattern fabric.

[0040] With reference to Figure 1 , the weft yarn 2 includes the first weft yarn 21 and the second weft yarn 22 arranged side by side. The first weft yarn 21 is spandex, which has good elasticity, so that the denim pattern fabric has good elasticity. Figure 1 and Figure 3 , the second weft yarn 22 is a core-spun yarn, which includes a polyester yarn core 221 and an acetate fiber layer 222 wrapped on the outer periphery of the polyester yarn core 221.

[0041] The acetate fiber layer 222 is composed of acetate fiber, which has good hydrophilicity. In the denim pattern fabric, the back of the denim pattern fabric has more weft yarns 2, and the polyester yarn core 221 of the second weft yarn 22 has poor moisture absorption, while the acetate fiber layer 222 has good moisture absorption. Thus, when the second weft yarn 22 absorbs sweat stains, the sweat stains will be adsorbed on the outer periphery of the second weft yarn 22 to facilitate the transmission of the sweat stains to the warp yarn 1. Thus, the denim pattern fabric has good sweat absorption and sweat-releasing performance, improving the comfort of the wearer.

[0042] With reference to Figure 3In the embodiment, the polyester yarn core 221 is hollow polyester, and the hollow chamber 2211 is arranged along the axial direction of the polyester yarn core 221. The cross section of the hollow chamber 2211 has a concave area 2212 along the cross section of the polyester yarn core 221. In the embodiment, the concave area 2212 of the cross section of the hollow chamber is spaced apart by two.

[0043] The implementation principle of the weft line 2 in the stretch denim fabric of the embodiment is as follows:

[0044] The first weft line 21 is spandex, which has good elasticity, so that the denim fabric has good stretch.

[0045] The polyester yarn core 221 of the first weft line 21 has a hollow chamber 2211, which can be used to store air, thereby improving the warmth retention performance of the second weft line 22. The hollow chamber 2211 of the polyester yarn can circulate air to improve the air permeability of the denim fabric. The cross section of the hollow chamber 2211 has a concave area 2212, which is beneficial to the deformation of the hollow chamber 2211 of the polyester yarn when the polyester yarn core 221 is deformed under pressure, so as to facilitate the circulation of air in the hollow chamber 2211, and improve the moisture absorption and air permeability of the denim fabric.

[0046] Hollow polyester is usually spun by melt spinning or wet spinning technology. In the melt spinning process, by special spinneret technology and reasonable adjustment of the spinning process, hollow polyester with different hollow degrees and shapes can be spun.

[0047] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
