Water Proof Finishing

The waterproof function of knitted products can be realized by coating finishing method and impregnation rolling method. Among them, fluorine-containing waterproofing agents can give excellent waterproof performance to the finished fabrics, but the fluorine-containing polymers will have toxic effects on human health and the environment. Therefore, the design and development of environmentally friendly fluorine-free waterproofing finishing agents has become an inevitable development trend for waterproof finishing.
