What is differential polypropylene fiber?

Differential polypropylene fiber usually refers to the physical or chemical modification treatment on the basis of the original fiber composition, so that the shape structure, physical and chemical properties of the fiber are significantly different from that of conventional chemical fiber.

The differential processing of differential polypropylene fiber is caused by some deficiencies of ordinary synthetic fibers, and most of them use simple imitation of natural fiber characteristics to improve fiber shape or performance.
