The Principle of Waterproof Fabric

In the state of water vapour, water particles are very small, according to the principle of capillary motion, and can smoothly penetrate the capillary to the other side, thus occurring the vapour permeability when the water vapour condensates into water droplets and particles become larger. Due to the surface tension of water droplets, water molecules can not be smoothly separated from the water droplet’s infiltration to the other side, so the porous vapour film has a waterproof function.

The Advantages Of Waterproof Fabric

The main functions of waterproof fabrics are moisture absorbent, breathable, windproof, and warm. From a technic standpoint, the requirements of waterproof fabrics are much higher than those of water-resistant fabrics; From the quality point of view, waterproof fabrics also have special functional characteristics. They can strengthen the fabric’s airtightness and water tightness. Their unique vapour permeability can make the structure of the internal water vapour quickly discharge to avoid the structure breeding mould, and keep the body always dry.

The Types of Waterproof Fabric

It can be divided into three categories: tightly woven, coating layer, membrane layer.

Main types of waterproof fabrics

When the fabric is tightly woven, it can be waterproof like waxed cotton, nylon, polyester, and wool. It couldn’t be 100% waterproof thus we need to put extra layers on the fabric surface. Companies like Gore-Tex has gained lots of patents on waterproof technolory.
