DETAILED DESCRIPTION

[0023] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Embodiment: A breathable polyester fabric, such as Figure 1 and Figure 2 As shown, it comprises an inner layer 1 and an outer layer 2, a plurality of moisture-conducting members 3 are arranged between the inner layer 1 and the outer layer 2, and a plurality of long strip-shaped support members 8 are fixedly connected to the end surfaces of the inner layer 1 and the outer layer 2 that are close to each other, and the support members 8 on the inner layer 1 and the support members 8 on the outer layer 2 are staggered along the length direction of the fabric, and the end surfaces of the support members 8 on the inner layer 1 and the support members 8 on the outer layer 2 that are close to each other are respectively against the two sides of the moisture-conducting member 3, and the moisture-conducting member 3 is bent by the support of the plurality of support members 8 on the inner layer 1 and the plurality of support members 8 on the outer layer 2. A continuous concave-convex structure is formed, and several moisture-conducting parts 3 are symmetrically arranged along the length direction of the fabric. After the inner layer 1 and the outer layer 2 are supported by the moisture-conducting parts 3 of the continuous concave-convex structure and several supporting parts 8, several breathable spaces 1 4 are formed between the moisture-conducting parts 3 and the inner layer 1, and several breathable spaces 2 6 are formed between the inner layer 1 and the outer layer 2 and several adjacent moisture-conducting parts 3. The gap between the inner layer 1 and the outer layer 2 is increased by the breathable spaces 1 4 and 2 6, thereby improving the air circulation effect between the inner layer 1 and the outer layer 2.

[0025] like Figure 1-Figure 3As shown, a plurality of ventilation grooves 9 arranged along the width direction of the fabric are provided on the end surface of the moisture-conducting member 3 close to the inner layer 1, and the ventilation grooves 9 between adjacent support members 8 on the inner layer 1 are interconnected with the breathable space 1 4, and the two ends of the ventilation grooves 9 are respectively interconnected with the adjacent breathable space 2 6, so that the breathable space 1 4 can be interconnected with the breathable space 2 6 through the plurality of ventilation grooves 9, further improving the air circulation effect between the inner layer 1 and the outer layer 2, and after the inner layer 1, the outer layer 2 and the plurality of moisture-conducting members 3 are sewed together and fixed by a sewing machine, a plurality of circular ventilation holes 1 5 are formed by simultaneously penetrating the inner layer 1, the moisture-conducting member 3 and the outer layer 2 with a laser puncher, so that the ventilation holes 1 5 on the inner layer 1, the outer layer 2 and the moisture-conducting member 3 are symmetrically arranged between the adjacent support members 8 along the thickness direction of the fabric, and the laser puncher is used again to simultaneously penetrate the inner layer 1 and the outer layer 2 between the adjacent moisture-conducting members 3 to form a plurality of circular ventilation holes 2 7, so that the ventilation holes 2 7 on the inner layer 1 and the outer layer 2 are symmetrically arranged along the thickness direction of the fabric.

[0026] like Figure 1-Figure 3 As shown, a plurality of air holes 15 are symmetrically arranged between adjacent supporting parts 8 on the inner layer 1 along the width direction of the fabric, so that the air holes 15 on the inner layer 1, the moisture-conducting part 3 and the outer layer 2 are interconnected with the air permeable space 14, and a plurality of air holes 27 are symmetrically arranged between adjacent moisture-conducting parts 3 along the width direction of the fabric, so that the air holes 27 on the inner layer 1 and the outer layer 2 are interconnected with the air permeable space 26. The air circulation effect between the inside and the outside of the fabric is enhanced by means of a plurality of interconnected air holes 15, air holes 27, air permeable space 14, air permeable space 26 and ventilation grooves 9, and the overall moisture dissipation performance of the fabric is further enhanced by means of a good air circulation effect.

[0027] like Figure 1 and Figure 6 As shown, the inner layer 1 is made by feeding the hygroscopic yarn 14 into the air-jet loom and weaving it in a convex strip structure. The hygroscopic yarn 14 is made by spirally winding a third strand 15 on a first strand 11 through a twisting machine. The first strand 11 is twisted by a twisting machine to form a polyester shaped fiber with a cross-section. The polyester shaped fiber with a cross-section is spun through a spinneret. The polyester fiber is shaped to increase its surface area and voids, so that the polyester shaped fiber has a certain air permeability, thereby improving the poor air permeability of the polyester fiber. The third strand 15 is twisted by a twisting machine to form a cotton fiber. The cotton fiber has good air permeability and hygroscopicity, so that the inner layer 1 can quickly absorb sweat when in contact with the skin to keep the skin dry.

[0028] like Figure 1 and Figure 2 and Figure 5As shown, the outer layer 2 is made by feeding the loose-wet yarn 13 into an air-jet loom and weaving it in a ribbed weave pattern. The plurality of support members 8 on the inner layer 1 and the plurality of support members 8 on the outer layer 2 are integrally formed by weaving the ribbed weave pattern. The loose-wet yarn 13 is made by spirally winding a second strand 12 around a first strand 11 through a twisting machine. The second strand 12 is twisted by flax fiber. The flax fiber has better moisture absorption and air permeability than cotton fiber. The strong air permeability of the flax fiber enables the outer layer 2 to quickly remove moisture from its interior.

[0029] like Figure 1 and Figure 4 As shown, the moisture-conducting component 3 is formed by feeding the moisture-conducting yarn 10 into a jet loom, weaving it into a base material through a plain weave, and then cutting it using a cutting machine. The moisture-conducting yarn 10 is twisted into a first strand 11 and a second strand 12 by a twisting machine. The loose yarn is wrapped and twisted to make the flax fiber content inside it greater than the flax fiber content in the moisture-conducting yarn 10. Therefore, the hygroscopicity of the moisture-conducting component 3 is greater than the hygroscopicity of the inner layer 1 and less than the hygroscopicity of the outer layer 2, so that the moisture absorbed in the inner layer 1 can be guided to the outer layer 2 through a plurality of moisture-conducting components 3 for dissipation, thereby maintaining the dryness of the inner layer 1 and the skin, and preventing the fabric from being wetted by sweat and sticking to the skin.

[0030] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
