What is waterproof and breathable composite fabric?

Waterproof and breathable fabric is a new type of textile fabric, which is composed of polymer waterproof and breathable material (PTFE membrane) and fabric. The main functions of waterproof and breathable fabrics are: waterproof, moisture-permeable, breathable, insulating, windproof, and warm. Its moisture permeability is 16,000g per square meter per 24 hours, its waterproof pressure can reach 8,000-20,000mm water column, and its insulation can reach 100,000 volts. The fabric can maintain its best performance in harsh environments and can adapt to temperatures from 427 degrees to minus 200 degrees. In terms of production technology, the technical requirements of waterproof and breathable fabrics are much higher than those of ordinary waterproof fabrics. At the same time, from a quality perspective, waterproof and breathable fabrics also have functional characteristics that other waterproof fabrics do not have. Waterproof and breathable fabrics not only enhance the air-tightness and water-tightness of the fabric, but also have unique breathable properties that can quickly discharge water vapor inside the structure to avoid mold breeding in the structure and keep the human body dry at all times. It perfectly solves the problem of breathability, windproof and waterproof. , warmth and other issues, it is a new type of fabric that is healthy and environmentally friendly.

In the state of water vapor, the water particles are very small. According to the principle of capillary movement, they can smoothly penetrate into the capillary tube to the other side, thus causing vapor permeability. When water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets (the water molecules “pull and compete” with each other), the water molecules cannot smoothly break away from the water droplets and penetrate to the other side, which is to prevent Water penetration occurs, making the breathable membrane waterproof.

Waterproof and breathable composite fabrics have multiple functions such as high windproof, high waterproof, moisture permeability, warmth retention, aging resistance, freezing resistance, and friction resistance. Mainly used in jackets, ski clothing, outdoor leisure clothing, jackets, sports and leisure clothing industry, special uniforms, medical and health materials, national defense and military industry, ski clothing fabrics, mountaineering clothing fabrics, cold-proof clothing fabrics, special clothing fabrics, high-end outdoor clothing , sporting goods, military clothing, aerospace, medical field, fire protection and other industries. Application: raincoats, raincoats, protective clothing, bags, tents, leisure supplies, medical and life-saving supplies.

Product features:
1. Waterproofness: Generally, the water pressure resistance of waterproof nylon is only 1000-2000mm, which can only withstand ordinary showers. The slightly better one is 5000mmH2O, which can withstand heavy rain; the waterproofness of PTFE/TPU/TPE composite fabric is as high as 10000mm.
2. Windproof: The special vertical and horizontal three-dimensional cross-arranged structure of the PTFE/TPU/TPE microporous film has an air penetration that is only half of that of ordinary man-made fiber or down clothing.
3. Moisture permeability: The specification of moisture permeability is g/m2/24h (grams per square meter per 24 hours). Generally, waterproof and moisture-permeable fabrics are only 2000-3000 g/m2/24h, while PTFE/TPU/TPE composite fabrics are moisture-permeable. The amount is as high as 8000-10000 g/m2/24h!
Double-sided knitted PTFE/TPU/TPE composite polar fleece fabric is a high-end functional fabric that has the functions of windproof and warm, abrasion resistance, high waterproof, high breathability and moisture permeability, acid and alkali resistance, etc. It is especially waterproof and breathable. The wet-function TPU composite polar fleece fabric has many advantages such as softer feel, strong peeling fastness, and tear resistance than ordinary waterproof and breathable fabrics.
