Main functions and status of waterproof cotton fabric

- Jan 29, 2019-

Waterproof cotton fabric literally means preventing water from penetrating from one side of the fabric to the other. It is a new type of textile fabric, its composition is made of polymer waterproof and breathable material (PTFE film) plus fabric composite fabric.

Why is waterproof cotton fabric waterproof?
The principle of waterproof fabric is that 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, making the gas permeable membrane waterproof.

The main function of waterproof cotton fabric
Waterproof, moisture permeable, breathable, insulated, windproof, etc. 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.
