[0018] 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.

[0019] like Figure 1 As shown, a waterproof and breathable polyester-cotton composite fabric comprises, from outside to inside, a waterproof and breathable membrane 1, a base fabric layer 2 and an inner layer 3. The lower surface of the base fabric layer 2 is provided with a plurality of first grooves 4 at equal intervals, and the upper surface of the inner layer 3 is provided with a plurality of corresponding second grooves 5 at equal intervals. After the base fabric layer 2 is connected to the inner layer 3, the first grooves 4 and the corresponding second grooves 5 form an air flow cavity. The inner layer 3 is provided with a plurality of air holes 6, which extend through the second grooves 5 and are connected to the air flow cavity. The waterproof and breathable membrane 1 adopts a polytetrafluoroethylene microporous membrane, and the middle portion of the first groove 4 is recessed inward to form a tensile-resistant opening 7.

[0020] See also Figure 2As shown, the base fabric layer 2 is woven from a first composite yarn, the first composite yarn includes a core 8 and a covering yarn 9 spirally wound around the outer surface of the core 8, the core 8 is formed by spirally twisting a plurality of first polyester fibers, the covering yarn 9 is made of bamboo charcoal fiber, the first polyester fiber is a special-shaped fiber structure, and its cross-section is "Y"-shaped.

[0021] See also Figure 3 As shown, the inner layer 3 is woven by the second composite yarn, which is formed by spirally twisting the second polyester fiber 10 and the cotton fiber 11, and the cross section of the second polyester fiber 10 is a hollow structure.

[0022] The working principle of this embodiment is as follows:

[0023] The fabric is breathable and prevents the intrusion of water molecules through the small holes in the waterproof and breathable membrane 1 on the outermost side. The holes in the breathable membrane are smaller than water vapor molecules but larger than water droplet molecules. Therefore, when water droplets from the outside hit the fabric, the water droplets cannot enter through the holes, thereby achieving a waterproof effect. At the same time, due to the existence of the holes, the water vapor generated by the human body can be discharged through the holes, thereby achieving a breathable effect.

[0024] At the same time, the airflow cavity formed between the base fabric layer 2 and the inner layer 3 can store a certain amount of air, capture and preserve heat, and form a warm and insulating layer. As the user moves, the airflow cavity will be squeezed and deformed, thereby promoting the air flow therein. The design of the anti-tension opening 7 on the first groove 4 can, on the one hand, increase the capacity of the airflow cavity, and on the other hand, enhance the lateral tensile resistance of the fabric. The base fabric layer 2 is made of a first polyester fiber with a special-shaped structure. The Y-shaped design increases the air flowability between the fibers, so that the base fabric layer 2 has air permeability, which promotes its air permeability with the waterproof and breathable membrane 1 and the inner layer 3 on the upper and lower sides.

[0025] 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.
