[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the inner layer 2 is woven from breathable and comfortable yarn 4, a number of polyester fibers 5 and a number of cotton fibers 6 are respectively put into a twisting machine for twisting to obtain a high-elastic yarn core and a soft coated yarn, the high-elastic yarn core and the soft coated yarn are fed into a mule spinning machine, and the soft coated yarn is spirally wound around the outer layer 1 of the high-elastic yarn core by the mule spinning process, the high strength and good elasticity of the polyester fiber 5 are utilized to ensure that the breathable and comfortable yarn 4 has good yarn strength and elasticity, the soft and porous characteristics of the cotton fiber 6 are utilized to ensure the air permeability and comfort of the breathable and comfortable yarn 4, the breathable and comfortable yarn 4 is fed into an air-jet loom, and the soft, warm and comfortable inner layer 2 is stably woven in accordance with the organization sequence of the twill weave, and the acid slurry is printed on the end surface of the inner layer 2 by a printing machine, and the acid slurry is acid-etching resistant The cotton fiber 6 with poor acid resistance retains the polyester fiber 5 with good acid resistance. The yarn count of the acid-etched part of the inner layer 2 becomes smaller, and a plurality of discharge grooves 1 203 and a plurality of discharge grooves 202 are formed on the end faces of both sides of the inner layer 2. The projection surfaces of the discharge grooves 1 203 and the discharge grooves 202 coincide with each other, and the weaving density at the bottom of the discharge grooves 1 203 and the discharge grooves 202 remains unchanged, but the yarn count becomes smaller, and its air permeability is improved.
