When a fiber has hydrophilicity, it absorbs water or mixes well with water. When water touches the surface of the fiber, it spreads and is absorbed quickly.For hydrophilic fibers, bicomponent fibers combining PP and PE are often used. However, in terms of cost, hydrophilic polyester fibers are superior to bicomponent fibers.It is mainly used to make diapers, feminine pad, and wet wipes.
