Description

Technical Field

[0001] The utility model relates to the technical field of textiles, and more particularly to a high-elasticity and high-toughness chemical fiber grey cloth. Background Art

[0002] Grey cloth is the basic material required to make various kinds of clothing. It can be made into the final clothing product through dyeing, printing, cutting, sewing and other processing steps. It can interpret the style and characteristics of clothing, and directly affect the color and shape of clothing.

[0003] However, during daily wear, clothing will constantly produce friction between the skin, especially the fabric at the knee and elbow joints, where the wear is more serious. At the same time, the fabric at the joints will be frequently pulled with the movement of the limbs. As the number of times it is worn increases, the fabric at the joints is prone to wear and tear, and loses elasticity and becomes loose and deformed, affecting the service life of the clothing.

[0004] Therefore, new solutions are needed to solve the problem that fabrics at the joints of clothing are easily worn and deformed. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a high-elasticity and high-toughness chemical fiber grey cloth, which can enhance the elasticity and toughness of the cloth through a new structural setting.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: the high-elasticity and high-toughness chemical fiber grey cloth includes an elastic layer, and the elastic layer includes a plurality of elastic parts and a plurality of stretching parts staggered along its length direction. A plurality of grooves are provided on both sides of the stretching part, and a wear-resistant sheet is provided on the same side of the plurality of stretching parts. A stretching space is formed between the wear-resistant sheet and the adjacent grooves, and an elastic strip is provided in the stretching space. The resilience of the wear-resistant sheet and the elastic strip are both greater than the resilience of the elastic layer, and a plurality of wear-resistant strips are provided on the side of the wear-resistant sheet away from the stretching part.

[0007] The utility model is further configured as follows: the plurality of grooves on both sides of the stretching portion are staggered along the length direction of the elastic layer; the cross-section of the stretching portion is wavy; the plurality of stretching portions and the plurality of grooves on both sides thereof are integrally formed on the elastic layer through a pleating process.

[0008] The utility model is further configured as follows: the wear-resistant sheet abuts against a plurality of wave crests on one side of the stretching portion, and the peripheral wall of the elastic strip abuts against the peripheral wall of the groove and the side wall of the wear-resistant sheet.

[0009] The utility model is further configured as follows: the width of the wear-resistant sheet is greater than the width of the stretching portion, and the two ends of the wear-resistant sheet are fixed to the elastic portions on both sides of the stretching portion by reciprocating stitching of high-tenacity yarns.

[0010] The utility model is further configured as follows: the wear-resistant sheet is made of high-tenacity yarn weaved in a convex strip structure, the several wear-resistant strips on the wear-resistant sheet are integrally formed by weaving the convex strip structure, and the elastic strip is formed by twisting multiple strands of high-tenacity yarn.

[0011] The utility model is further configured as follows: the high-tenacity yarn is formed by twisting a first strand and a second strand, the first strand is formed by twisting spandex fiber, the second strand is formed by twisting nylon fiber, and the count of the first strand is greater than the count of the second strand.

[0012] The utility model is further configured as follows: the elastic layer is made by weaving elastic yarn in a plain weave manner, the elastic yarn is made by spirally winding a third strand around a first strand, the third strand is made by twisting cotton fiber, and the weaving density of the wear-resistant sheet is greater than the weaving density of the elastic layer.

[0013] In summary, the utility model has the following beneficial effects: the grooves on both sides of the stretching part enable the elastic layer to obtain a larger stretching distance, thereby improving the ductility of the elastic layer and preventing the fabric from being broken by excessive pulling. The cotton fiber has good moisture absorption, air permeability and softness, and the spandex fiber has good elasticity and elastic recovery. The elastic layer made by wrapping the cotton fiber on the spandex fiber can quickly recover to its original shape after stretching while ensuring wearing comfort, thereby improving the shape retention of the elastic layer. The nylon fiber has high toughness and is not easy to wear and break. By blending the nylon fiber and the spandex fiber with a high weaving density The manufactured wear-resistant sheet has stronger tensile resilience than the elastic layer, so that the several wear-resistant sheets can generate greater rebound force when stretched together with the elastic layer. The several elastic strips will form rebound force when subjected to the pressure generated by the stretching part and the wear-resistant sheet after stretching, thereby driving the elastic layer to rebound quickly, thereby enhancing the shape retention of the elastic layer. The contact area between the fabric and the skin when worn is reduced by the several wear-resistant sheets and the several wear-resistant strips on their end faces, thereby reducing the wear of the fabric. At the same time, the nylon fiber with a larger diameter will first contact and rub against the skin, further improving the wear resistance of the wear-resistant sheet, so that the manufactured fabric is not easy to wear and deform during long-term wear.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0020] Example: High elasticity and high toughness chemical fiber fabric, such as Figure 1 and Figure 4 As shown, it includes an elastic layer 1, which is made by feeding an elastic yarn 12 into an air-jet loom and weaving it in a plain weave manner. The elastic yarn 12 is made by spirally winding a third strand 13 on a first strand 10 through a ring spinning process. The third strand 13 is twisted by a twisting machine to twist cotton fiber, and the first strand 10 is twisted by a twisting machine to twist spandex fiber. Cotton fiber has good moisture absorption, air permeability and softness, and spandex fiber has good elasticity and elastic recovery. The elastic layer 1 made by blending cotton fiber and spandex fiber can quickly recover to its original shape after stretching while ensuring wearing comfort, thereby improving the shape retention of the elastic layer 1.

[0021] like Figure 1 As shown, the elastic layer 1 includes a plurality of elastic portions 2 and a plurality of stretching portions 3 staggered along its length. A plurality of grooves 4 with a triangular cross-section are provided on both sides of the stretching portion 3. The plurality of grooves 4 on both sides of the stretching portion 3 are staggered along the length of the elastic layer 1. The plurality of stretching portions 3 and the plurality of grooves 4 on both sides of the stretching portion 3 are processed by a pleating machine in a row pleating manner and then integrally formed on the elastic layer 1, so that the cross-section of the stretching portion 3 is wavy. The plurality of stretching portions 3 enable the elastic layer 1 to obtain a larger stretching distance, thereby preventing the elastic layer 1 from being broken due to excessive pulling.

[0022] like Figure 1-Figure 3As shown, the elastic strip 7 is formed by twisting two high-tenacity yarns 9 in an "S" twisting manner through a twisting machine and then cutting them using a cutting machine. The elastic layer 1 is laid flat and then several elastic strips 7 are placed in several grooves 4 on the upper side of several stretching parts 3. The elastic strip 7 is arranged horizontally at one end of the trough away from the stretching part 3 and one end of the crest of the stretching part 3. Several stretching parts 3 are located on the same side of the several elastic strips 7. A rectangular wear-resistant sheet 5 is provided. The wear-resistant sheet 5 and the stretching part 3 are symmetrically arranged along the thickness direction of the elastic layer 1. The width of the wear-resistant sheet 5 is 1 / 4" (1 / 4). The length is greater than the width of the stretching part 3, and the two ends of the length of the wear-resistant sheet 5 are respectively sewn back and forth using high-tenacity yarn 9 by a sewing machine and then fixed on the elastic part 2 on both sides of the stretching part 3, so that the side of the wear-resistant sheet 5 close to the elastic layer 1 is offset against several peaks on the side of the stretching part 3 close to the wear-resistant sheet 5. At this time, several stretching spaces 6 with triangular cross-sections are formed between the wear-resistant sheet 5 and several adjacent grooves 4, and the peripheral wall of the elastic strip 7 is offset against the inner wall of the groove 4 and the side of the wear-resistant sheet 5 close to the base layer, thereby fixing the elastic strip 7 in the stretching space 6.

[0023] like Figure 1-Figure 3 As shown, the wear-resistant sheet 5 is made by feeding high-tenacity yarn 9 into an air-jet loom and weaving it into a base layer by a convex strip structure, and then cutting it using a cutting machine. The high-tenacity yarn 9 is twisted by a twisting machine to form a first strand 10 and a second strand 11 by an "S" twist. The second strand 11 is twisted by a twisting machine to form nylon fiber. Nylon fiber has high toughness, and the resilience of spandex fiber and the resilience of nylon fiber are both greater than the resilience of cotton fiber, so that the elastic strip 7 made by blending nylon fiber and spandex fiber has a stronger resilience than the elastic layer 1, and the weaving density of the wear-resistant sheet 5 is 1. The thickness of the wear-resistant sheet 5 is 197*184 / cm², and the weaving density of the wear-resistant sheet 5 is greater than that of the elastic layer 1. Therefore, the wear-resistant sheet 5 made by blending nylon fiber and spandex fiber with a higher weaving density has stronger resilience than the elastic layer 1. When the wear-resistant sheets 5 are stretched together with the elastic layer 1, they can generate a larger resilience. When the elastic strips 7 are subjected to the pressure generated by the stretching part 3 and the wear-resistant sheet 5 after stretching, they will form a resilience, thereby driving the elastic layer 1 to recover its original shape faster after stretching, further enhancing the shape retention of the elastic layer 1, so that the made clothes are not easily deformed during long-term wear.

[0024] like Figure 1-Figure 3As shown, a plurality of long wear-resistant strips 8 are provided on the side of the wear-resistant sheet 5 away from the stretching portion 3, and the plurality of wear-resistant strips 8 are symmetrically arranged along the length direction of the elastic layer 1. The plurality of wear-resistant strips 8 on the wear-resistant sheet 5 are all integrally formed by weaving a convex strip structure. The wear-resistant sheet 5 and the plurality of wear-resistant strips 8 on its end surface reduce the contact friction area between the clothing and the skin when worn, thereby reducing the wear of the clothing. The number of the first strand 10 is greater than the number of the second strand 11, so that the diameter of the first strand 10 is smaller than the diameter of the second strand 11, so that the second strand 11 with a larger diameter on the wear-resistant sheet 5 will first contact and rub against the skin. Nylon fiber has strong wear resistance and tear resistance, so that the second strand 11 is not easy to wear and break, so that the made clothing is not easy to wear and break during long-term wear and has a longer service life.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
