Polypropylene staple fiber is made of polypropylene as raw material through melting, drafting, spinning and cutting. In the process of making PP staple fiber can be added according to the need of functional masterbatch, such as anti-aging masterbatch, flame retardant masterbatch and so on to increase the performance of PP staple fiber. Polypropylene staple fiber for felt is a polypropylene staple fiber specially used for the manufacture of felt, used for filter materials.

Polypropylene staple fiber characteristics: 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 the sea water inside do not worry; The hygroscopicity of pp staple fiber is small, almost no hygroscopicity; Polypropylene staple fiber is an environmentally friendly and pollution-free product.

Polypropylene staple fiber is mainly used in needle-punched carpet, automobile interior, non-woven fabric, rope, decorative materials, medical and sanitary products and so on. Short fiber Long bundles of chemical fibers are cut or pulled into lengths equivalent to those of various natural fibers. Natural fibres such as whisker 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 cotton, wool, carpet and medium-length short fibers. They can be spun pure or blended with different proportions of natural fibers or other fibers to make strips, fabrics and felts. For example, the general grade asphalt carbon fiber was cut into 150mm length, 15μm diameter, 800MPa strength, 41GPa modulus of carbon fiber, and phenolic carbon fiber (length 70mm, 200MPa strength, 14μm diameter) in a ratio of 8:2, to produce stable and uniform yarn. Woven into a variety of shapes of fabric or cut fibers used in composite materials such as cement, aluminum alloy reinforcement.
