Polypropylene staple fiber with polyamide fiber, polyester fiber light, viscose fiber light comparison has its own advantages and characteristics, polypropylene staple fiber with polypropylene resin as the main raw material, after melting spinning, drafting, curling, drying shape cut, packaging and other processes of color and colorless, stipulated denier number and length of fluffy fiber.

So what are the high quality properties of polypropylene staple fiber ? Light, its density of 0.9 ~ 0.92 grams/cubic centimeter, in all synthetic fibers is the lightest, it is 20% lighter than polyamide fiber, 30% lighter than polyester fiber, 40% lighter than viscose fiber; High strength (dry state and wet state are the same), good wear resistance and resilience; Anti-microbial, not mold and moth; Chemical resistance is also better than the general synthetic fiber. In addition, compared with other synthetic fibers, polypropylene fiber has the best electrical insulation and heat preservation, its resistivity is very high (7×1019 ohms · cm), and its thermal conductivity is very small.

However, the melting point of polypropylene staple fiber is low (165 ~ 173℃), and the light and heat stability is poor, so the heat resistance and aging resistance of polypropylene staple fiber is poor. Usually, heat stabilizer and anti-aging agent are added to improve its performance. Its hygroscopic property and dyeing property is the worst in synthetic fiber, the moisture regain rate is less than 0.03%, ordinary dyes can not make it color, so in the spinning of raw material polypropylene to add a certain amount of coloring master particles to make the fiber color.

Hubei BOTAO COMPOSITE FIBER CO., Ltd. was established in October 2000, specializing in the production and sales of polypropylene fiber, polyester, composite fiber, poly (lactic acid) staple fiber, 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 imported fiber production line, fixed assets of more than 100 million yuan, annual output of polypropylene staple fiber 50,000 tons, polyester staple fiber 20,000 tons, composite fiber 10,000 tons, the annual output value of more than 500 million yuan.
