[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1 As shown, a tear-resistant, waterproof and breathable polyester-cotton composite fabric is composed of a surface layer 1, an intermediate layer 2 and a base fabric layer 3 in sequence. The surface layer 1 is bent outward at equal intervals to form protrusions 4, and elastic threads 5 are passed through the protrusions 4. A plurality of air holes 6 are opened at the top of the protrusions 4. A waterproof and breathable membrane 7 is arranged between the intermediate layer 2 and the surface layer 1, and the base fabric layer 3 is woven with polyester-cotton mixed threads.

[0017] In this embodiment, a plurality of cavities 8 are provided in the middle layer 2 , and the cavities 8 are filled with hydrophilic fibers. The cavities 8 are located below the air holes 6 , and the middle layer 2 is made of bamboo charcoal fibers.

[0018] In this embodiment, a plurality of micropores are formed on the base fabric layer 3 , and the micropores extend through to the lower surface of the middle layer 2 , and the micropores are staggered with the air holes 6 .

[0019] See also Figure 2As shown, the polyester-cotton blended yarn includes a yarn core and a covering yarn, wherein the covering yarn is spirally wound on the outside of the yarn core, the yarn core is spirally twisted by polyester fiber 9 and polypropylene fiber 10, and the covering yarn is twisted by cotton fiber 11.

[0020] The working principle of this embodiment is as follows:

[0021] The surface layer 1 is bent upward to form protrusions 4 distributed at equal intervals. The protrusions 4 can increase the wear resistance of the surface layer 1 of the fabric on the one hand, and on the other hand, when the fabric is pulled, the bent protrusions 4 are deformed and stretched by force, thereby increasing the tensile resistance of the surface of the fabric, avoiding the fabric from being torn, and quickly recovering through the resilience of the elastic thread 5 as soon as the external force disappears;

[0022] The ventilation holes 6 and micropores are used to realize the circulation of internal and external air in the middle layer 2 to achieve a breathable effect, and the waterproof breathable membrane 7 is used to prevent the penetration of external water stains. Even if external water stains penetrate, they will be quickly absorbed by the hydrophilic fibers in the cavity 8 and will not continue to penetrate into the base fabric layer 3 and contact the skin.

[0023] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
