Waterproof fabric is a new type of textile fabric. Its composition is made of polymer waterproof and breathable material (PTFE film) plus fabric composite fabric.
Principle of waterproof cloth
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 is to prevent The penetration of water occurs so that the vapor permeable membrane has a waterproof function.
Advantages of waterproof fabric
The main functions of waterproof and breathable fabrics are: waterproof, moisture permeable, breathable, insulated, windproof and warm. In terms of production process, the technical requirements of waterproof and breathable fabrics are much higher than those of ordinary waterproof fabrics. At the same time, from the perspective of quality, waterproof and breathable fabrics also have functional features not found in other waterproof fabrics. The waterproof and breathable fabric enhances the airtightness and watertightness of the fabric, and its unique steam permeability can quickly discharge the water vapor inside the structure, avoiding the structure of mold and mold, and keeping the body always dry, perfectly solving the ventilation and windproof, waterproof, The problem of keeping warm is a new type of fabric that is healthy and environmentally friendly.
The real waterproof fabric can withstand the seepage pressure and not seep water in the long-term humid environment. For example, walking for a long time in the wind and rain, walking on the wet ground, will not seep.
