Polypropylene staple fiber is made of polypropylene as raw material through 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.

Polypropylene staple fiber  according to the specifications of natural fibers 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 fibers or other fibers to make yarn strips, fabrics and felt. For example, the general grade asphalt carbon fiber was cut into 150mm long, 15μm in diameter, 800MPa in strength, 41GPa in modulus, and the phenolic carbon fiber (70mm in length, 200MPa in strength, 14μm in diameter) in a ratio of 8:2 to produce stable and uniform yarn strips. Fabric woven into various shapes or cut into fibers used as reinforcement for composite materials such as cement and aluminum alloys.

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