The main functions of Waterproof Fabric are: waterproof, moisture permeable, breathable, insulating, windproof and warm-keeping. In terms of manufacturing technology, the technical requirements of waterproof and breathable fabrics are much higher than those of ordinary waterproof fabrics. At the same time, in terms of quality, waterproof and breathable fabrics also have functional characteristics that other waterproof fabrics do not have. Waterproof fabric not only strengthens the air tightness and water tightness of the fabric, but also has its unique vapor permeability, which can enable the water vapor in the structure to be rapidly discharged, avoid mold growth in the structure, and keep the human body dry all the time. It perfectly solves the problems of air permeability, wind resistance, waterproof, heat preservation and the like. It is a new type of healthy and environment-friendly fabric.
Under the condition of water vapor, water particles are very fine, and according to the principle of capillary movement, they can smoothly penetrate into the capillary to the other side, thus causing vapor permeation. When the water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets (the water molecules "pull against each other"), the water molecules cannot smoothly separate from the water droplets and penetrate to the other side, that is, water permeation is prevented, and the vapor permeable membrane has a waterproof function.
Real waterproof fabrics can withstand the pressure of water seepage even in humid climate for a long time without water seepage. For example, long-term outdoor walking in stormy weather, kneeling or sitting on wet ground will not cause water seepage.
