Description

Technical Field

[0001] The utility model relates to the technical field of textile fabrics, in particular to an elastic biological-based wrinkle-feeling fabric. Background Art

[0002] In recent years, the development of textile fabrics has mainly focused on functionality, fashion, safety, comfort, and environmental protection. In 2022, the two ministries issued the "Guiding Opinions on the High-Quality Development of the Chemical Fiber Industry and Industrial Textiles Industry", which also mentioned that by 2025, the proportion of green fibers will increase to more than 25%, and the output of bio-based chemical fibers and degradable fiber materials will increase by more than 20% annually. Bio-based nylon 56 fiber is derived from bio-based raw materials and is a green fiber material with native flame retardancy, good moisture absorption and heat resistance, and a relatively soft texture. It is an important fiber raw material for the preparation of high-end fabrics.

[0003] Sports have become an indispensable part of life. Elastic fabrics are becoming more and more popular because they can provide consumers with a sense of comfort and freedom. However, the overall visual three-dimensional sense of the elastic fabrics currently available is relatively lacking, and the fashion sense is insufficient. Therefore, the utility model is based on providing an elastic bio-based nylon wrinkle fabric. Utility Model Content

[0004] The utility model aims to overcome the problem that the elastic fabric in the prior art lacks a three-dimensional sense, and to provide a green and environmentally friendly bio-based wrinkle-feeling fabric with elasticity.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] A bio-based wrinkle fabric with elasticity comprises a main fabric layer, wherein the main fabric layer is a plain weave formed by interlacing warp yarns and weft yarns one above the other, wherein the warp yarns are nylon bio-based fibers obtained by twisting ATY with a denier number of 45D-70D and FDY with a denier number of 20D-40D together, and the weft yarns are ATY+FDY nylon bio-based fibers consistent with the warp yarns, which are coated with 40D spandex yarns, and the coating method is an empty bag.

[0007] Furthermore, the ratio of the denier number of ATY to the denier number of FDY in the warp yarn and the weft yarn is set between 1.5 and 2.5.

[0008] Furthermore, the density of the warp yarn is controlled to be 135T-145T, and the density of the weft yarn is controlled to be 90T-100T.

[0009] Furthermore, the main fabric layer is coated with a bio-based water-repellent layer.

[0010] After adopting the above structure, the utility model provides an elastic bio-based wrinkled fabric. The warp yarn in the main layer of the fabric is selected from nylon bio-based fibers which are ATY with a denier number of 45D-70D and FDY with a denier number of 20D-40D. The weft yarn is selected from ATY+FDY nylon bio-based fibers which are consistent with the warp yarn and are coated with 40D spandex yarn. The coating method is selected as an empty bag to make the fabric elastic. Since the boiling shrinkage of ATY fiber is larger than that of FDY fiber, when the fabric is subjected to high temperature, the shrinkage of FDY is smaller than that of ATY, and the ATY fiber will bulge; in addition, the weft yarn selects ATY+FDY nylon bio-based fiber to cover 40D spandex yarn, and adopts the inner air bag covering method. The nylon bio-based fiber has relatively small internal force on the spandex yarn. When it is subjected to hot, humid and high temperature, the spandex yarn can be recycled to the maximum extent, so that the amount of nylon bio-based fiber per unit area is increased; coupled with the wool loop effect of the ATY yarn itself, the above three factors work together to make the wrinkle effect of the main layer of the fabric more obvious, and the plain weave structure can make the wrinkle of the fabric more uniform, thereby enhancing the beauty and fashion.

[0013] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0014] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0015] like Figure 1 As shown, the utility model discloses an elastic bio-based wrinkle fabric, which comprises a fabric main body layer 1 and a bio-based water-repellent layer 2 arranged on the fabric main body layer 1 .

[0016] The bio-based water-repellent layer 2 mainly comes from polyaliphatic compounds of fruits such as apple peels and banana peels.

[0017] The lower layer is the main fabric layer 1, which is a plain weave woven by warp yarns 11 and weft yarns 12. The utility model selects the plain weave mainly because the internal stress of the plain weave fabric itself is more balanced than that of twill, lattice, jacquard and other fabrics, which can make the wrinkles of the fabric more uniform and enhance the beauty and fashion.

[0018] The warp yarn 11 is a nylon bio-based fiber made by plying ATY with a denier number of 45D-70D and FDY with a denier number of 20D-40D. Since the boiling shrinkage of ATY fiber is larger than that of FDY fiber, when subjected to high temperature, FDY shrinks less than ATY, and ATY fiber will bulge. It is not suitable to choose ATY+DTY or DTY+FDY because although the boiling shrinkage of these two yarn combinations is inconsistent, the difference is not large, and the bulge (wrinkling) phenomenon is not obvious. In order to ensure a significant wrinkling effect, the ratio of the denier number of ATY to the denier number of FDY should be controlled between 1.5-2.5.

[0019] The weft yarn is made of ATY+FDY nylon bio-based fiber that is the same as the warp yarn and is coated with 40D spandex yarn. The coating method is an empty package, and the spandex yarn is an elastic yarn. Due to the use of the empty package coating method, the ATY+FDY nylon bio-based fiber has a relatively small force on the internal spandex yarn. When it is subjected to hot, humid and high temperatures, the spandex yarn can be recycled to the maximum extent, increasing the number of ATY+FDY nylon bio-based fibers per unit area. In addition, due to the inconsistent boiling and shrinkage inside the ATY+FDY nylon bio-based fiber, plus the wool loop effect of the ATY yarn itself, the wrinkle effect is more obvious under the simultaneous action of the three.

[0020] The density of the warp yarn is controlled at 135T-145T, and the density of the weft yarn is controlled at 90T-100T. The total density should not be too large. Although it can produce a corresponding wrinkle feeling, it is easy to produce obvious creases on the fabric due to the limited shrinkage space. If the total density is too small, the texture and wrinkle style of the fabric will be relatively poor.

[0021] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
