[0019] The utility model will be described in detail in combination with the drawings and examples.
[0020] Embodiment: an anti-deformation knitted fabric, as shown in Figure 1 、 Figure 3 and Figure 4 , comprising an elastic layer 1, the elastic layer 1 is made by feeding elastic yarn 10 into the knitting machine and knitting by means of spiral stitch, the fabric made by means of spiral stitch has good elasticity and ductility, the elastic yarn 10 is made by spiral winding a third strand 11 on a first strand 8 through the processing technology of ring spinning, the first strand 8 is twisted by spandex fiber, the spandex fiber has high elasticity and elastic recovery ability, so that the elastic layer 1 made can quickly recover to its original shape after stretching, has good shape retention, the third strand 11 is twisted by wool fiber through a twisting machine, the wool fiber has good moisture absorption, air permeability and soft and comfortable touch, the elastic layer 1 made by wrapping wool fiber on polyester fiber can quickly absorb sweat when it comes into contact with the skin, improving the comfort of the fabric when worn, at the same time, the wool fiber itself has a certain elasticity and shape retention, further improving the shape retention of the elastic layer 1.
[0021] As shown in Figure 1 and Figure 2 , the elastic layer 1 is provided with a plurality of grooves one 2 and a plurality of grooves two 3 on both sides, respectively, the plurality of grooves one 2 and the plurality of grooves two 3 are staggered along the length direction of the elastic layer 1, the plurality of grooves one 2 and the plurality of grooves two 3 are integrally formed by pleating the elastic layer 1 through the pleating way of I-shaped pleat by a pleating machine, a plurality of elastic pieces 4 are fixedly connected to one side of the elastic layer 1 located in the groove one 2, the width of the elastic piece 4 is greater than the width of the groove one 2, the plurality of elastic pieces 4 are located directly above the plurality of grooves one 2, the width and thickness of the anti-tension piece 6 are smaller than the width and depth of the groove two 3, the plurality of anti-tension pieces 6 are located on the bottom surface of the plurality of grooves two 3, the air circulation effect between the fabric and the skin is increased through the groove two 3, the length of both sides of the elastic piece 4 and the length of both sides of the elastic layer 1 and the anti-tension piece 6 are fixed by reciprocally sewing with elastic yarn 7 by a sewing machine, the middle part of the elastic piece 4 and the bottom surface of the groove one 2 are fixed by reciprocally sewing with elastic yarn 7, so that a plurality of stretching spaces 5 are formed between the plurality of elastic pieces 4 and the plurality of grooves one 2, the elastic layer 1 obtains a larger stretching distance through the plurality of stretching spaces 5 and the plurality of grooves two 3, which can be used to make clothes of different sizes for different body shapes, improving the applicability of the fabric.
[0022] As shown in Figures 1-3As shown, the spring sheet 4 is made by feeding spring yarn 7 into an air-jet loom and weaving it into a spiral structure. The spring yarn 7 is formed by twisting a first strand 8 and a second strand 9 using a twisting machine. The second strand 9 is formed by twisting nylon fiber. Nylon fiber has high elasticity and elastic recovery performance, as well as strong tensile strength. The elasticity and elastic recovery ability of nylon fiber and spandex fiber are greater than those of wool fiber. The weaving density of the elastic layer 1 is less than that of the spring sheet 4, thus making the spring sheet... The elastic recovery ability of the elastic sheet 4 is greater than that of the elastic layer 1, while the extensibility of the elastic sheet 4 is less than that of the elastic layer 1. The tensile sheet 6 is made by weaving the elastic yarn 7 with a double-rib structure, which makes the elastic recovery ability of the tensile sheet 6 greater than that of the elastic layer 1. Several elastic sheets 4, several tensile sheets 6 and the elastic yarn 7 used for sewing and fixing can generate a large elastic force after being stretched together with the elastic layer 1, thereby driving the elastic layer 1 to quickly return to its original shape after stretching, further enhancing the overall shape retention of the fabric.

The weaving density of the tensile sheet 6 is greater than that of the elastic sheet 4, which makes the extensibility of the tensile sheet 6 less than that of the elastic sheet 4. Through several elastic sheets 4 and several tensile sheets 6, the elastic layer 1 can be restricted from being overstretched, thereby preventing the elastic layer 1 from being overstretched and losing its elasticity or breaking, thus improving the overall service life of the fabric.
