The main function and status of waterproof cotton fabric

The waterproof cotton fabric literally means to prevent water from penetrating from one side of the fabric to the other. It is a new type of textile fabric, which is composed of polymer waterproof breathable material (polytetrafluoroethylene film) and fabric composite fabric. In the following, the cotton cloth is mainly for you to analyze why the waterproof cotton fabric is waterproof.

Why is the waterproof cotton fabric waterproof?

The principle of waterproof fabric is that in the state of water vapor, water particles are very small, and according to the principle of capillary movement, the capillary can smoothly penetrate to the other side, resulting in air permeability. When 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 to the other side. This is to prevent water penetration and waterproof the breathable membrane.

Waterproof, moisture-permeable, breathable, thermal insulation, windproof, etc. In terms of production technology, the technical requirements of waterproof and breathable fabrics are much higher than ordinary waterproof fabrics. At the same time, from a quality perspective, waterproof and breathable fabrics also have functional features not found in other waterproof fabrics.
