Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to an anti-wrinkle weft-elastic cotton fabric. Background Art

[0002] Cotton fiber is a natural fiber in nature. As a textile raw material with a long history, it has always been active on the stage of the textile industry. The fabric woven from cotton fiber has the advantages of being comfortable and skin-friendly, soft and delicate, moisture-absorbing and breathable, with a soft luster and high wearing comfort. It is also favored by consumers for its natural, harmless to the human body, comfortable, renewable, biodegradable and other advantages. However, the fabric woven from pure cotton fiber has very poor elasticity and elastic recovery. Its clothing is extremely prone to wrinkles during daily wearing and washing, and it is difficult to recover flat after wrinkling, resulting in a significant decline in the aesthetic appearance of the fabric surface, reducing the grade of the clothing, and further affecting its wearing life, bringing many inconveniences to people.

[0003] In order to solve the problem of poor anti-wrinkle performance of cotton fabrics, the Chinese patent with the publication number CN217047776U proposes an anti-wrinkle polyester elastic fabric, which includes a base fabric layer; the base fabric layer is woven by warp yarns and weft yarns, and both the warp yarns and the weft yarns include anti-wrinkle polyester-cotton elastic yarns, and the anti-wrinkle polyester-cotton elastic yarns are formed by twisting and plying a polyester-ammonia core-spun yarn and a cotton-ammonia core-spun yarn; the covering yarn of the polyester-ammonia core-spun yarn is polyester, and the core yarn is a ply yarn formed by twisting and plying spandex and conductive elastic fiber; the covering yarn of the cotton-ammonia core-spun yarn is cotton fiber, and the core yarn is a ply yarn formed by twisting and plying spandex and vinylon; the base fabric layer adopts a twill weave. Although the fabric of the above prior art improves the anti-wrinkle performance of cotton fabrics, the materials in contact with the skin are polyester (synthetic fiber) and cotton fiber, increasing the proportion of non-natural fibers in contact with the skin, reducing the affinity of the fabric for the skin, and because synthetic fibers are not easy to dye, resulting in impure fabric color and fabric patterns, reducing the texture and grade of cotton fabric products.

[0004] Therefore, there is a great room for improvement in the prior art. Summary of the Utility Model

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and propose an anti-wrinkle weft-elastic cotton fabric.

[0006] To achieve the above purpose, the utility model is realized through the following technical solutions:

[0007] The utility model provides an anti-wrinkle weft-elastic cotton fabric, which is formed by weaving warp yarns and weft yarns. The warp yarns include core yarns and a first wrapping yarn wrapped around the core yarns;

[0008] The weft yarns include elastic double-core yarns and a second wrapping yarn wrapped around the elastic double-core yarns;

[0009] Both the first wrapping yarn and the second wrapping yarn are cotton fibers.

[0010] In the utility model, by arranging cotton fibers to wrap the core yarn and the elastic double-core yarn respectively, the fabric has excellent wrinkle resistance under the stretching and elastic action of the elastic double-core yarn; moreover, the outer wrapping yarns of the core yarn and the elastic double-core yarn are both cotton fibers, which improves the affinity and comfort of the fabric to the skin, and makes the fabric surface have excellent dyeability and a casual feeling, which is beneficial to improving the texture and grade of the fabric.

[0011] According to the above scheme, the core yarn is a polyamide monofilament.

[0012] It can be understood that the monofilament is a continuous long filament spun through a single-hole spinneret, which has excellent strength and toughness. The utility model sets the polyamide monofilament as the core yarn, which provides good mechanical and physical properties, enables it to have sufficient strength and toughness, and improves the stretchability of the fabric.

[0013] According to the above scheme, the fineness of the polyamide monofilament is 20-40D.

[0014] By setting the fineness of the polyamide monofilament, the proportion of the polyamide monofilament in the warp yarn is reduced, so that the original properties of the cotton fibers wrapped outside it will not be damaged.

[0015] According to the above scheme, the elastic double-core yarn includes spandex fiber and high-elastic yarn, and the high-elastic yarn is helically wound around the spandex fiber.

[0016] The high-elastic yarn has excellent elasticity and elastic recovery, good dimensional stability, high breaking strength, high elongation rate, and high wear resistance. Winding and combining it with the spandex fiber plays a role in restricting the excessive stretching of the spandex filament, can effectively prevent the spandex from breaking due to excessive stretching under the action of external force, and can also use its good wear resistance to protect the spandex fiber, avoiding the spandex from breaking due to various factors such as friction during the stretching deformation of the fabric. By using spandex fiber and high-elastic yarn to form the elastic double-core yarn, the skeleton feel of the fabric is improved, making the fabric more textured.

[0017] According to the above scheme, the high-elastic yarn is preferably a polyester high-elastic yarn. The polyester high-elastic yarn has characteristics such as good stability and wrinkle resistance.

[0018] According to the above scheme, the fineness of the spandex fiber is 20-40D, and the fineness of the high-elastic yarn is 20-50D.

[0019] According to the above solution, the first wrapping yarn is helically wound and coated on the core yarn. Through the above structural arrangement, the first wrapping yarn is tightly coated on the core yarn, improving the bonding strength between the two; the first wrapping yarn can effectively protect the core yarn and make the warp yarn in contact with the skin be natural fiber.

[0020] According to the above solution, the second wrapping yarn is helically wound and coated on the elastic double-core yarn. The second wrapping yarn is tightly coated on the elastic double-core yarn, improving the bonding strength between the two; the second wrapping yarn can effectively protect the elastic double-core yarn and make the weft yarn in contact with the skin be natural fiber.

[0021] According to the above solution, the yarn counts of both the warp yarn and the weft yarn are 30 - 60S.

[0022] By reasonably setting the yarn counts of the warp yarn and the weft yarn, the gram weight and thickness of the fabric are stably controlled, thus having the advantages of being light, wrinkle-resistant, breathable, comfortable, etc., and being suitable for making spring and summer casual clothing products.

[0023] According to the above solution, the fabric structure adopts one of 2 / 2 twill, 3 / 1 twill, 2 / 1 twill, jacquard and satin texture.

[0024] The beneficial effects of the present utility model are as follows:

[0025] By arranging cotton fibers to wrap the core yarn and the elastic double-core yarn respectively, the fabric has excellent wrinkle resistance under the stretching and elastic action of the elastic double-core yarn; moreover, the outer wrapping yarns of the core yarn and the elastic double-core yarn are both cotton fibers, improving the affinity and comfort of the fabric to the skin, and making the fabric surface have excellent dyeability and casual sense, which is beneficial to improving the texture and grade of the fabric.
