Waterproof and breathable fabric is a new type of textile fabric, which is composed of high polymer waterproof and breathable material (PTFE membrane) and fabric. According to different product requirements, it can be made into two-layer composite and three-layer composite. It is widely used in outdoor clothing, mountaineering clothing, windbreaker, raincoat, shoes, hats, gloves, cold-proof jackets, sporting goods, medical equipment, etc., and is gradually applied to fashion clothing.

The main functions of waterproof and breathable fabrics are: waterproof, moisture-permeable, breathable, insulating, and warm. Its moisture permeability is 16000g per square meter per 24 hours, the waterproof pressure can reach 8000-20000mm water column, and the insulation height can reach 100,000 volts. The fabric can maintain its best performance in harsh environments, and can adapt to temperatures ranging from 427 degrees to minus 200 degrees. In terms of production process, the technical requirements of waterproof and breathable fabrics are much higher than that of ordinary waterproof fabrics; at the same time, from the perspective of quality, waterproof and breathable fabrics also have functional characteristics that other waterproof fabrics do not have. The waterproof and breathable fabric enhances the air-tightness and water-tightness of the fabric, and at the same time, its unique vapor-permeable performance can quickly discharge the water vapor inside the structure, avoid the growth of mold in the structure, and keep the human body always dry. It is a new type of fabric that is healthy and environmentally friendly.

Specifically, waterproof and moisture-permeable fabric means that water does not soak into the fabric under a certain pressure, but the sweat emitted by the human body can be conducted to the outside through the fabric in the form of water vapor, so as to avoid the accumulation of sweat and condensation between the body surface and the fabric. Maintain the comfort of garments, it is a high-tech, unique functional fabric
