DETAILED DESCRIPTION

[0019] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Example: High elastic breathable chemical fiber fabric, such as Figure 1 and Figure 6 As shown, it includes an inner layer 1 and an outer layer 2 which are fixedly connected to each other. The inner layer 1 is made by feeding a hygroscopic yarn 11 into a jet loom and weaving it in a plain weave manner. The hygroscopic yarn 11 is made by spirally winding a second strand 12 on a third strand 13 through a fancy twisting machine. The second strand 12 is twisted by a cotton fiber through a twisting machine. The third strand 13 is twisted by a cross-section spandex shaped fiber through a twisting machine. The cross-section spandex shaped fiber is spun through a spinneret. The spandex fiber is shaped to obtain a larger gap and surface area, thereby improving the hygroscopicity and air permeability of the spandex fiber. Cotton fiber has good hygroscopicity and air permeability, so that the inner layer 1 made of the hygroscopic yarn 11 can absorb the sweat produced by the skin in time. At the same time, the cotton fiber has the characteristics of softness and skin-friendliness, so that the made inner layer 1 can provide a soft touch when it is against the skin, thereby improving the wearing comfort of the fabric.

[0021] like Figure 1 and Figure 7As shown, the outer layer 2 is made by feeding the moisture-dispersing yarn 14 into an air-jet loom and weaving it in a convex strip structure. The moisture-dispersing yarn 14 is made by spirally winding a fourth strand 15 on a third strand 13 through a fancy twisting machine. The fourth strand 15 is twisted by flax fiber through a twisting machine. Flax fiber has better moisture absorption and air permeability than cotton fiber and spandex shaped fiber. Its special porous structure and large surface area can quickly dissipate moisture, so that the moisture absorption of the outer layer 2 is greater than that of the inner layer 1. The outer layer 2 can absorb moisture in the inner layer 1 in time and dissipate it quickly, thereby keeping the inner layer 1 and the skin dry and avoiding discomfort caused by the fabric adhering to the skin through sweat.

[0022] like Figure 1-Figure 4 As shown, the end surface of the inner layer 1 close to the outer layer 2 is provided with a plurality of long strip-shaped grooves 3, the length of the grooves 3 is the same as the length of the inner layer 1, and the plurality of grooves 3 are arranged in an array along the width direction of the inner layer 1, and an elastic strip 4 is arranged in each of the plurality of grooves 3, the length of the elastic strip 4 is the same as the length of the groove 3, and the end surface of the outer layer 2 close to the inner layer 1 is provided with a plurality of long strip-shaped support strips 5, the length of the support strips 5 is the same as the width of the outer layer 2, and the plurality of support strips 5 are integrally formed on the outer layer 2 by weaving a convex strip organization, and the plurality of support strips 5 are arranged in an array along the length direction of the outer layer 2 The diameter of the elastic strip 4 is greater than the depth of the groove 3, so that the side of the elastic strip 4 away from the inner layer 1 passes through the groove 3 and abuts against the side of the support strip 5 away from the outer layer 2. The inner layer 1 and the outer layer 2 are located at a number of support strips 5 and are deformed by the pressure approaching each other, so that the side of the support strip 5 away from the outer layer 2 is driven to abut against the side of the inner layer 1 with the groove 3, so that a number of breathable spaces 6 are formed between a number of adjacent support strips 5 and the outer layer 2, the inner layer 1 and a number of elastic strips 4, and a number of depressions 28 are formed integrally after the pressure forms on the sides of the inner layer 1 and the outer layer 2 away from each other.

[0023] like Figure 1-Figure 4As shown, the inner layer 1 and the outer layer 2 are respectively penetrated with a plurality of circular air holes 1 7 and a plurality of circular air holes 2 8, the length of the support strip 5 is the same as the width of the outer layer 2, the plurality of air holes 1 7 and the plurality of air holes 2 8 are arranged in an array between adjacent support strips 5 along the width direction of the inner layer 1, the air holes 2 8 and the air holes 1 7 are the same size and are symmetrically arranged up and down along the thickness direction of the inner layer 1, and the plurality of air holes 1 7 and the plurality of grooves 3 are staggered along the width direction of the inner layer 1, so that the plurality of air holes 1 7 and the plurality of air holes 2 8 are staggered with the plurality of air holes 1 7 and the plurality of air holes 2 8. The spaces 6 are interconnected, and the diameter of the support strip 5 is smaller than the width of the groove 3, so that several adjacent breathable spaces 6 are interconnected through several grooves 3. The air circulation effect on both sides of the fabric is improved through several interconnected breathable spaces 6, air hole 1 7, air hole 2 8 and grooves 3. The gap between the fabric and the skin is increased through several depressions 28 on the inner layer 1, and the air circulation effect between the fabric and the skin is improved, which avoids the stuffiness of the fabric when worn. At the same time, the good air circulation effect further enhances the moisture dissipation performance of the fabric.

[0024] like Figure 1-Figure 7 As shown, the fabric has a larger stretching distance through a plurality of air holes 7 and a plurality of air holes 8, thereby improving the ductility of the fabric and preventing the fabric from being broken and damaged due to excessive pulling by a large tensile force. The spandex shaped fiber has good elasticity and resilience, so that the fabric is not easy to lose elasticity in the case of frequent stretching, thereby improving the shape retention of the fabric. The elastic strip 4 is made by twisting two first strands 10 by an "S" twisting method through a twisting machine. The first strand 10 is twisted by a twisting machine to form the spandex fiber. The first strand The count of thread 10 is 30S, and the counts of the second thread 12, the third thread 13 and the fourth thread 15 are 60S, so that the spandex fiber content in the elastic strip 4 is greater than the spandex fiber content in the hygroscopic yarn 11 and the moisture-releasing yarn 14. Therefore, the elasticity and resilience of the elastic strip 4 are greater than the resilience of the hygroscopic yarn 11 and the moisture-releasing yarn 14. After being stretched together with the inner layer 1 and the outer layer 2, a large resilience force can be generated by the elastic strips 4, thereby driving the inner layer 1 and the outer layer 2 to rebound quickly after stretching. It is recommended not to enhance the shape retention of the fabric.
