Polypropylene staple fiber is made of polypropylene through melting, drafting, spinning, cutting and other processes. In THE process OF making polypropylene staple fiber, WE can add functional masterbatch, such as anti-aging masterbatch, flame retardant masterbatch, etc., to increase the performance of polypropylene staple fiber. Polypropylene staple fiber for felt is a kind of polypropylene staple fiber specially used for making felt and can be used as filter material.

The characteristics ofpolypropylene staple fiber: polypropylene staple fiber density is small, light, can float on the water; Polypropylene colored yarn has high strength and strong tensile resistance. Polypropylene staple fiber has a certain acid and alkali corrosion resistance, even if immersed in seawater are not to worry about; The hygroscopicity of polypropylene staple fiber is small, almost no hygroscopicity; Polypropylene staple fiber is environmental protection and pollution-free products.

Polypropylene staple fiber according to the specification of natural fiber can be divided into cotton type, wool type, carpet type and long type of short fiber. They can be spun pure or blended with natural or other fibers in different proportions to make yarn, fabric and felt. For example, universal grade bituminous carbon fiber cut into 150mm long, 15μm diameter, 800MPa strength, 41GPa modulus of carbon fiber, and phenolic carbon fiber (70mm length, 200MPa strength, 14μm diameter) mixed in the ratio of 8:2, to produce a stable uniform yarn. Woven into various shapes of fabric or short cut into fibers used in composite materials such as cement, aluminum alloy reinforcement.
