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

According to the specification of natural fiber, polypropylene staple fiber can be divided into cotton, wool, carpet and medium length staple fiber. 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.

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 polypropylene staple fiber is small, almost no hygroscopicity; Polypropylene staple fiber is environmentally friendly and pollution-free product.

Hubei Botao Synthetic fiber Co., Ltd. was established in October 2000, specializing in polypropylene staple fiber, polyester staple fiber, composite fiber, poly (lactic acid) staple fiber production, sales, products are mainly used in non-woven fabric, automotive interior, geotextile, carpet, filtration and other industries. The company is located in Jingmen city, Hubei Province, now has six branches, covering a total area of 300,000 square meters. The company is equipped with import fiber production line, fixed assets of more than 100 million yuan, with an annual output of 50,000 tons of polypropylene staple fiber, 20,000 tons of polyester staple fiber, 10,000 tons of composite fiber, and an annual output value of more than 500 million yuan.
