[0017] The utility model will be described in detail in combination with the drawings and examples.
[0018] A kind of composite fabric with low washing shrinkage, such as Figure 1 And Figure 2As shown, including the base layer 1, the two side end faces of the base layer 1 are provided with a plurality of air-permeable grooves 2, the cross-sectional shape of the air-permeable groove 2 is a four-star shape, a plurality of air-permeable grooves 2 are arranged in a matrix on the base layer 1, and a plurality of anti-sticking rings 3 are fixedly connected to the two side end faces of the base layer 1. The horizontal section of the anti-sticking ring 3 is a square ring, the anti-sticking ring 3 surrounds a plurality of recesses 4 on the two side end faces of the base layer 1, the air-permeable groove 2 is located in the recess 4, the air-permeable groove 2 makes the thickness of the base layer 1 thinner, and the air-permeability of the base layer 1 as a whole is enhanced. The air-permeable groove 2 with a four-star cross-sectional shape deforms when the base layer 1 is stretched, which increases the elasticity and tensile strength of the base layer 1 as a whole. The anti-sticking ring 3 on the two side end faces of the base layer 1 can reduce the contact area between the base layer 1 and the skin in a humid state, improve the wearing comfort, and at the same time, the anti-sticking ring 3 can reduce the tension directly received by the air-permeable groove 2, and further improve the tensile effect of the base layer 1 as a whole.
[0019] As shown in Figure 1 , Figure 2 and Figure 3 , the base layer 1 is woven from low-shrinkage yarn 5, the low-shrinkage yarn 5 is provided as a core-spun yarn, the yarn core 6 of the core-spun yarn is twisted by a plurality of polyester fibers through a twisting machine, and the outer wrapping yarn 7 of the core-spun yarn is twisted by a plurality of Tencel filaments through a twisting machine. The polyester fibers and Tencel filaments both have the characteristics of low shrinkage and good strength. The specific parameters of the low-shrinkage yarn 5 are as follows: 66D polyester FDY x 120D / 80F Tencel filament, composition: 47%P53%NEWCELL. The yarn core 6 and the outer wrapping yarn 7 are fed into a walking spindle spinning machine, and the outer wrapping yarn 7 is spirally wrapped on the outside of the yarn core 6 through a walking spindle spinning process to obtain the low-shrinkage yarn 5. The fabric organization of the base layer 1 is set to plain weave, the low-shrinkage yarn 5 is fed into a jet loom, and the base layer 1 with smooth surface and high structural strength is woven in sequence and stably according to the plain weave. By utilizing the low-shrinkage characteristics of polyester fibers and Tencel filaments, the base layer 1 can be machine washed, and the water shrinkage rate can be controlled within 1%.
[0020] As shown in Figure 1 and Figure 2As shown in the drawings, the air-permeable grooves 2 on the two side end faces of the base layer 1 are formed by the acid-etching process, and the forming method is as follows: the acid-etching process is used to print the acid-etching paste on the surface of the base layer 1, and the printed pattern is a four-corner star shape and arranged in a matrix array on the base layer 1, since the base layer 1 is knitted by the low-shrinkage yarn 5, the outer cover yarn 7 of the low-shrinkage yarn 5 is made of Tencel filament which has poor acid resistance, and the yarn core 6 is made of polyester fiber which has good acid resistance, the acid-etching paste etches the Tencel filament which has poor acid resistance and retains the polyester fiber which has good acid resistance, that is, only the core yarn is retained after the acid-etching of the core-in-sheath yarn, so the acid-etching part of the low-shrinkage yarn 5 becomes thinner, and the air-permeable grooves 2 with a four-corner star-shaped horizontal cross section are formed on the two side end faces of the base layer 1, then the excess acid-etching paste is washed away, and the acid-etching part of the yarn on the base layer 1 becomes thinner, but the knitting density does not change, so the pore size at the groove bottom of the air-permeable grooves 2 is larger, and the air-permeability is better than that of other parts of the base layer 1.
[0021] As shown in the drawings, Figure 1 and Figure 2 The anti-sticking rings 3 on the two side end faces of the base layer 1 are formed by sewing with polyester yarn, and the automatic sewing machine is used to sew near the air-permeable grooves 2, and the sewing path shape of the automatic sewing machine is a square ring, and the polyester yarn floats on the two side surfaces of the base layer 1 to form the anti-sticking rings 3 with a square ring-shaped horizontal cross section during the sewing process, the anti-sticking rings 3 are arranged in a symmetrical array on the two side end faces of the base layer 1, and the anti-sticking rings 3 are arranged on the two side end faces of the base layer 1 to surround a plurality of recesses 4, the air-permeable grooves 2 are located in the recesses, and the center positions of the anti-sticking rings 3 coincide with the center positions of the air-permeable grooves 2, the plurality of air-permeable grooves 2 and the anti-sticking rings 3 arranged in a symmetrical array on the two side end faces of the base layer 1 ensure the uniformity of the overall structure of the base layer 1, and have an aesthetic effect, and the anti-sticking rings 3 arranged on the base layer 1 will deform correspondingly after being pulled, thereby reducing the pulling force directly borne by the air-permeable grooves 2, improving the overall tensile effect of the base layer 1, and making the air-permeability of the base layer 1 more uniform.
