[0003] With the holding and promotion of more and more sports events, people's enthusiasm for participating in sports is increasing, and people also pay more attention to the comfort of wearing during exercise. Frequent large-scale exercise and stretching may cause the elasticity of the fabric to decrease and deform.

[0021] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Example:

[0023] like Figure 1-Figure 3As shown, the high-elastic tensile polyester grey fabric comprises a comfortable inner layer 1 and an elastic outer layer 2 which are fixedly connected to each other by sewing yarns. The comfortable inner layer 1 is hot-pressed to form a plurality of rectangular grooves 3 arranged in pairs. A first strand formed by twisting a plurality of polyether ester elastic fibers is woven into a fabric in a ribbed weaving manner. The ribbed weaving manner can obtain a depression with a stable structure between two adjacent ribs, namely a through groove 1 5. The fabric is then cut into long tensile strips 4 by a cutting machine, so that the cross-sectional shape of the tensile strips 4 is concave. A side of the tensile strips 4 away from the through groove 1 5 is hot-pressed to form a plurality of through grooves 2 6 with a rectangular cross-sectional shape. A plurality of elastic yarns 9 are bundled and twisted to form elastic lines 7. The width of the through grooves 2 6 is equal to the diameter of the elastic lines 7. Therefore, the tensile strips 4 can be firmly sewn to the comfortable inner layer 1 through the elastic lines 7, so that the tensile strips 4 and the grooves 3 are perpendicular to each other. The tensile strips 4 reinforce the comfortable inner layer 1 while also limiting the pulling range of the fabric, thereby reducing deformation or The elastic line 7 can be stretched and retracted without losing its shape, so that the tensile strip 4 has a strong stretchability in its length direction and can return to its original shape in time. The fabric can automatically recover after being pulled, thereby enhancing the elasticity of the comfortable inner layer 1. The elastic outer layer 2 is hot-pressed to form a plurality of tensile grooves 8 that are the same as the central axis of the elastic line 7 in the length direction. The depth of the tensile groove 8 is equal to the radius of the elastic line 7. The elastic line 7 is simultaneously engaged with the through groove 2 6 and the tensile groove 8 to limit the relative position of the comfortable inner layer 1 and the elastic outer layer 2, thereby improving the overall tensile resistance of the fabric. The groove 3, the through groove 2 6 and the tensile groove 8 generated by hot pressing can enhance the structural strength of the fabric. The width of the through groove 1 5 is greater than that of the through groove 2 6. After the elastic line 7 fixes the tensile strip 4, a stretching space is left between the through groove 2 6. When the fabric is stretched along the width direction of the tensile strip 4, the side walls of the through groove 2 6 are inclined to both sides to stretch the fabric, which can disperse the pulling force, reduce the risk of the yarn breaking due to direct pulling, and improve the stretching effect of the fabric.

[0024] like Figure 1 and Figure 4 As shown, the comfortable inner layer 1 is woven from comfortable yarn 10, and the comfortable yarn 10 includes a core yarn 11 and a covering yarn 12. The core yarn 11 is twisted by a plurality of spandex fibers, and the covering yarn 12 is twisted by a plurality of polyester fibers. The covering yarn 12 is spirally wound around the outer side of the core yarn 11. The spandex fiber has good elasticity and elastic recovery. The comfortable inner layer 1 can quickly respond to deformation and return to its initial state after deformation, thereby improving wearing comfort. The polyester fiber has good structural strength and wear resistance, and can protect the stability of the yarn core function.

[0025] like Figure 1 and Figure 5As shown, the elastic outer layer 2 is woven from elastic yarns 9, which are twisted by a plurality of second strands 13 and a third strand 14, the second strands 13 are twisted by a plurality of polyether ester elastic fibers, and the third strands 14 are twisted by a plurality of polyester fibers. The polyether segment of the polyether ester elastic fiber has good softness, a relatively long chain, and is easily elongated and deformed, and the polyester segment of the polyether ester elastic fiber is relatively short, which acts as a node when the fiber is deformed by force, giving the fiber elastic recovery properties. Blending with polyether ester elastic fibers can process polyester fibers into elastic textiles, thereby making the elastic outer layer 2 have better elastic recovery force.

[0026] like Figure 1-Figure 5 As shown, when the fabric needs to be made, first, a number of polyester fibers are put into a twisting machine and twisted to form a core yarn 11, and a number of spandex fibers are put into a twisting machine and twisted to form a covering yarn 12. The core yarn 11 and the covering yarn 12 are spirally wound through a spindle spinning process to form a comfortable yarn 10, and then the comfortable yarn 10 is woven into a comfortable inner layer 1 through a jet loom, and a number of grooves 3 arranged in pairs are formed on the comfortable inner layer 1 through a hot press. A number of polyether ester elastic fibers are put into the twisting machine to form a first strand of yarn, and then a number of first strands are put into the jet loom to weave into the fabric in a convex strip weaving manner, and then a hot press is used to heat press the side of the fabric away from the convex strip tissue to form a through groove 2 6, which is cut into long strip-shaped tensile strips 4 by a cutting machine. It should be noted that the convex strip tissue is retained on the cut tensile strip 4 The depression between two adjacent convex strips is a through groove 5. The side of the tensile strip 4 with the through groove 5 faces the comfortable inner layer 1 and is placed on the comfortable inner layer 1 in a direction perpendicular to the groove 3. After a number of polyether ester elastic fibers and polyester fibers are put into a twisting machine to form a second strand 13, a number of second strands 13 are put into the twisting machine for twisting to form an elastic yarn 9. The elastic yarn 9 is then woven by a jet loom to form an elastic outer layer 2. A number of elastic yarns 9 are bundled and twisted to form an elastic line 7. The tensile strip 4 is sewed to the comfortable inner layer 1 with the elastic line 7 by a sewing machine. A number of tensile grooves 8 having the same central axis as the length direction of the elastic line 7 are formed by heat pressing on one side of the elastic outer layer 2 close to the comfortable inner layer 1 by a hot press. The elastic outer layer 2 and the comfortable inner layer 1 are sewed together by a sewing machine to finally form the fabric.

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.
