Polypropylene staple fiber uses polypropylene resin as the main raw material, and undergoes processes such as melt spinning, drawing, crimping, drying, shaping and cutting, and packaging to produce colored and colorless, fluffy fibers with a specified denier and length.

Polypropylene staple fiber properties:

1. It has excellent moisture conductivity, flexibility, netting and combability, and excellent thermal adhesion.

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

Polypropylene staple fiber is mainly used in needle-punched carpets, automotive interiors, non-woven fabrics, ropes, decorative materials, medical and sanitary products, and so on. Short fiber is also called cut fiber. The chemical fiber long fiber bundle is cut or stretched into fibers equivalent to the length of various natural fibers. 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, wool, carpet and medium-length. They can be spun purely or blended with natural fibers or other fibers in different proportions to make yarns, fabrics and felts. For example, cut the general-purpose pitch carbon fiber into 150mm long, 15μm diameter, 800MPa strength, and 41GPa modulus, and mix it with phenolic carbon fiber (length 70mm, strength 200MPa, diameter 14μm) in a ratio of 8:2 to produce Stable and even yarn. Woven into various shapes of fabrics or chopped into fibers for reinforcement of composite materials such as cement and aluminum alloy.

Polypropylene staple fiber product performance:

1. Polypropylene staple fiber has excellent moisture conductivity, flexibility, web formation and combability, and excellent thermal adhesion.

2. High strength, strong curling elasticity, light weight, low melting point, good surface permeability, acid and alkali resistance and abrasion resistance are better than other fibers

Polypropylene staple fiber is mainly used for: needle-punched non-woven fabrics, sanitary non-woven fabrics, needle-punched carpets, automotive interior fabrics, geotextiles, speaker cloths, filter cloths, filter yarns, clothing linings, artificial fur, spinning, Spinning yarn, filter material, adsorption material and other fields.
