After the polypropylene staple fiber is spun, a micro air chamber is formed between the fibers, and the capillary effect is increased, so it absorbs wet air and has good heating property. Fiber bending stiffness is small, made of textiles feel extremely soft, with good drape.

In the process of making polypropylene staple fiber, functional masterbatches can be added as needed, such as anti-aging masterbatches, flame retardant masterbatches, etc., to increase the performance of polypropylene staple fiber. Polypropylene staple fiber for felt is a polypropylene staple fiber specially used to make felt for filter materials.
