Polypropylene staple fiber uses polypropylene resin as the main raw material, and is made into colored and colorless fluffy fibers with specified denier and length through melt spinning, drafting, crimping, drying, shaping, cutting, packaging and other processes.

Polypropylene staple fiber properties:

1. It has excellent moisture conductivity, flexibility, web-forming and carding properties, and excellent thermal adhesion.

2. Polypropylene staple fiber has high strength, strong curling elasticity, light weight, low melting point, good surface permeability, acid and alkali resistance and wear resistance are better than other fibers

Polypropylene staple fibers are mainly used in needle-punched carpets, automotive interiors, non-woven fabrics, ropes, decorative materials, medical and sanitary products, etc. Short fiber is also called cut fiber. Chemical fiber long fiber bundles are cut or broken into fibers corresponding to various natural fiber lengths. Natural fibers such as whiskers and asbestos can also be used. Short fiber limit, the length is generally 35 ~ 150mm. According to the specifications of natural fibers, it can be divided into short fibers such as cotton type, wool type, carpet type and medium and long type. They can be spun purely or blended with natural or other fibers in varying proportions to make sliver, fabric and felt. For example, general-grade pitch carbon fiber is cut into 150mm long, 15μm in diameter, carbon fiber with a strength of 800MPa and a modulus of 41GPa, and mixed with phenolic carbon fiber (length 70mm, strength 200MPa, diameter 14μm) in a ratio of 8:2 to obtain Stable and uniform sliver. Woven into various shapes of fabrics or chopped fibers for reinforcement of composite materials such as cement and aluminum alloys.
