The main functions of waterproof breathable fabric are: waterproof, moisture permeable, breathable, insulation, windproof, warm. In terms of production technology, the technical requirements of waterproof and breathable fabric are much higher than that of ordinary waterproof fabric. At the same time, from the perspective of quality, waterproof breathable fabric also has other waterproof fabrics do not have functional characteristics. Waterproof and breathable fabric not only strengthens the air tightness and water tightness of fabric, but also has unique vapor permeability, which can make the water vapor in the structure discharge quickly, avoid the accumulation of mold in the structure, and keep the human body dry all the time. It perfectly solves the problems of air permeability, windproof, waterproof, warmth and so on. It is a new kind of healthy and environmental protection fabric.
Real waterproof fabric can withstand the pressure of water seepage in a humid climate for a long time, without water seepage. For example, walking outside in the rain for a long time, kneeling or sitting on the wet ground will not allow water to seep through.
