With the continuous development of society and the continuous improvement of people's living standards, the demand for various functions of fabrics is getting higher and higher. Today's fabrics have been continuously improved in the direction of comfort and functionality. Therefore, clothing fabrics with different functions have come into being, including a fabric with waterproof effect. Its advantages include strong waterproof performance, wear resistance, easy cleaning, etc. It is composed of a polymer waterproof membrane and fabric composite, and is widely used in the production of outdoor clothing, mountaineering clothes, windbreakers, raincoats, shoes, hats and gloves, cold-proof jackets and other products.

However, in order to achieve a good waterproof effect for the fabric, the weaving density of the fabric is increased to reduce the pores generated during weaving, and a waterproof layer is added to the surface of the fabric. Therefore, while the fabric achieves a waterproof effect, its breathability is relatively poor, which makes the waterproof fabric feel stuffy when worn as clothing. The sweat generated on the body surface cannot be dissipated in time, causing the fabric to stick to the skin surface and feel uncomfortable, affecting the wearing comfort. Therefore, a new structure is proposed to solve the problem that the fabric has a good waterproof effect but relatively poor breathability.

Therefore, new solutions need to be proposed to solve this problem.
