Polypropylene staple fiber has its own advantages and characteristics compared with polyamide fiber, polyester fiber light, viscose fiber light, polypropylene staple fiber polypropylene resin as the main raw material, through melt spinning, drafting, crimping, drying, cutting, packaging and other processes to produce colored and colorless, specified denier and length of fluffy fiber.


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 and wet state of the same), good wear resistance and resilience; Anti-microbial, no mold and no decay; Chemical resistance is also better than the general synthetic fiber. In addition, compared with other synthetic fibers, polypropylene fiber has good electrical insulation and heat retention, 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 stability of light and heat is poor, so the heat resistance and aging resistance of polypropylene staple fiber are poor, and the heat stabilizer and anti-aging agent are usually added to improve its performance. Its hygroscopic and dyeing properties are the worst in synthetic fibers, the moisture recovery rate is less than 0.03%, and ordinary dyes can not make it colored, so a certain amount of coloring masterbatch is added to raw polypropylene in spinning to make the fibers colored.


Hubei Botao Synthetic Fiber Co., Ltd. was founded in October 2000, located in Jingmen City, Hubei Province, specializing in the production and sales of polypropylene, polyester, composite fiber, polylactic acid staple fiber, the products are mainly used in non-woven fabrics, automotive interior, geotextiles, carpets, filtration and other industries.
