    In the state of water vapor, the water particles are very small, and according to the principle of capillary movement, the capillary can be smoothly infiltrated to the other side, thereby causing vapor permeability. When the water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets (water molecules collide with each other), the water molecules cannot smoothly escape from the water droplets and penetrate into the other side, which prevents them. The penetration of water occurs, making the vapor permeable membrane waterproof.
    use
    Waterproof and moisture permeable composite fabric has many functions such as high windproof, high waterproof, moisture permeable, warm, aging resistant, antifreeze and abrasion resistant. Mainly used for jackets, ski clothing, outdoor casual wear, jackets, sports and leisure clothing, special uniforms, medical and health materials, national defense military industry, ski clothing fabrics, mountaineering clothing fabrics, winter clothing fabrics, special clothing fabrics, high-end outdoor clothing , sporting goods, military clothing, aerospace, medical field, fire protection and other industries. Applications: Raincoats, rainwear, protective clothing, luggage, tents, leisure products, medical life-saving supplies.
    Product Features:
    1. Waterproof: Generally, the waterproof pressure of nylon is only 1000-2000mm, which can only withstand general showers. The better one is 5000mmH2O, which can withstand heavy rain. The waterproofness of PTFE/TPU/TPE composite fabric is up to 10000 mm.
    2. Windproof: PTFE/TPU/TPE microporous film has a special vertical and horizontal three-dimensional cross-arrangement structure, and its air penetration is only one-half of that of ordinary man-made fiber or down garment.
    3. Moisture permeability: The specification of moisture permeability is g/m2/24h (gram per square meter per 24 hours), and the general waterproof and moisture permeable fabric is only 2000-3000 g/m2/24h, while the PTFE/TPU/TPE composite fabric is wet. The amount is up to 8000-10000 g/m2/24h!
    Double-knit fabric PTFE/TPU/TPE composite fleece fabric is a high-grade functional fabric with windproof and warmth, abrasion resistance, high waterproof, high vapor permeability, acid and alkali resistance, especially waterproof The wet-functional TPU composite fleece fabric has many advantages such as soft hand feeling, strong peeling fastness and tear resistance compared with ordinary waterproof and steam-permeable fabrics.
