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

The characteristics of polypropylene staple fiber: the density of polypropylene staple fiber is small, light weight, and can float on the water; The polypropylene colored yarn has high strength and strong tensile resistance. Polypropylene staple fiber has a certain acid and alkali resistance to corrosion, even if it is soaked in seawater, do not worry; The hygroscopicity of polypropylene staple fiber is small and almost non-hygroscopicity. Polypropylene staple fiber is environmentally friendly and pollution-free products.

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