Polypropylene staple fiber is mainly used for acupuncture carpet, automobile interior, non-woven fabric, rope, decorative materials, medical and health supplies and so on. Short fiber is also known as cut fiber. Long bundles of chemical fibers are cut or pulled into fibers of the same length as the various natural fibers. Natural fibres such as whiskers and asbestos can also be used. Short fiber limit, the length is generally 35 ~ 150mm. According to the specification of natural fiber can be divided into cotton type, wool type, carpet type and long 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.

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

The characteristics of polypropylene staple fiber: polypropylene short 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.
