[Common textiles manual] Waterproof textiles

Overview

Waterproof textiles. The waterproof property of a fabric means that the fabric resists the permeability of water molecules. The traditional treatment method is to coat the surface of the fabric with a water-impermeable coating, such as polyvinyl chloride resin, polyurethane resin, etc., in order to eliminate the water permeability. Such methods have been used in the past, but it is not a solution to the problem. The best method, because the coating can not pass water vapor, it limits the evaporation of human sweat after evaporation, and condensation on the inner surface of the fabric, very uncomfortable to wear.

Today's waterproof fabrics are generally required to have a breathable function. Therefore, they are generally referred to as waterproof and breathable fabrics or waterproof and breathable fabrics. Waterproof and breathable fabric is a new type of fabric, the main function of waterproof, moisture permeable, breathable, insulation, wind and warm.

Water-proof and moisture-permeable refers to the fact that water is not immersed in the fabric under a certain pressure, but the sweat emitted by the human body can be transmitted through the fabric to the outside world in the form of water vapor. Waterproof and moisture-permeable textiles, also known as "breathable textiles," are functional fabrics that combine waterproof, moisture-permeable, wind-proof, and warmth retention.
