Waterproof Fabric Breathable Membrane Has A Waterproof Function

Waterproof fabric is a new type of textile fabric, its composition is made of polymer waterproof and breathable material (PTFE membrane) and cloth composite fabric.

The main functions of waterproof and breathable fabrics are: waterproof, moisture permeable, breathable, heat preservation, windproof, and warmth. In the production process, the technical requirements of waterproof and breathable fabrics are much higher than those of general 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. The waterproof and breathable fabric not only enhances the airtightness and water tightness of the fabric, but also has unique breathability, which can quickly discharge water vapor in the structure, avoid the formation of mold in the structure, and keep the human body dry all the time. It perfectly solves the problems of breathability, wind resistance, water resistance, and warmth. It is a new type of healthy and environmentally friendly fabric.

Real waterproof fabrics can withstand the pressure of water seepage in a humid climate for a long time without water seepage. For example, walking in the wind and rain for a long time, kneeling or sitting on damp ground, will not seep water.

Working principle:

In the state of water vapor, the water particles are very small. According to the principle of capillary movement, they can smoothly penetrate the capillary to the other side, thus causing vapor transmission. When the water vapor condenses and turns 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 escape from the water droplets and penetrate to the other side, which is to prevent Water infiltration occurs, giving the vapor permeable membrane a waterproof function.
