Polypropylene staple fiber is mainly used in needled carpet, automotive interior, non-woven fabrics, ropes, decorative materials, medical and health supplies and so on. short fiber is also called cut fiber. Long bundles of chemical fibers are cut or pulled into lengths equivalent to the various natural fibers. Natural fibers such as whiskers and asbestos are also available. Polypropylene staple fiber boundary, the length is generally 35 ~ 150mm. According to the specifications of natural fiber can be divided into cotton type, wool type, carpet type and medium long short fiber. They can be spun pure or blended with different proportions of natural or other fibers to make yarn strips, fabrics and blankets. For example, the general grade asphalt carbon fiber was cut into 150mm long, 15μm diameter, 800MPa strength, 41GPa modulus of carbon fiber, and phenolic carbon fiber (70mm length, 200MPa strength, 14μm diameter) in a ratio of 8:2 mixed to produce stable and uniform yarn. Fabric woven into various shapes or cut into fibers used as reinforcement for composite materials such as cement and aluminum alloys.

Polypropylene staple fiber is made from polypropylene by melting, drawing, 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 specially used to make felt polypropylene staple fiber for filter materials.

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