Hubei Botao Synthetic Fiber Co., Ltd. specializes in producing polypropylene staple fiber, polypropylene staple fiber, colored polypropylene staple fiber , flame retardant polypropylene staple fiber and felt polypropylene staple fiber. The main products of the company are polypropylene staple fiber: specification 0.3 -- 110dt, length 5 -- 150mm, annual output of 30,000 tons, complete color. Polypropylene staple fiber is mainly used for: Sanitary materials for non-woven fabric (such as women's sanitary napkins, baby diapers, medical masks, clothes and hats, etc.), needled carpet, electric blanket fabric, filter cloth, textile, automotive decorative cloth, clothing lining, artificial fur, wool, yarn spinning, sanitary products hot rolled non-woven fabric, polypropylene yarn spinning, interior decoration, speaker cloth, spun yarn, filter material, adsorption material, cigarette filter nozzle, rope, wool strip, Filter materials and other fields.

The above polypropylene staple fiber products can be added according to user requirements of anti-aging agents, flame retardant, anti-UV agents to increase the properties of polypropylene staple fiber.

So what are the excellent properties of polypropylene staple fiber? Light weight, its density is 0.9 ~ 0.92 g/cc, 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 is the same), good wear resistance and resilience; Anti-microbial, no mold and no decay; Chemical resistance is also better than common synthetic fibers. In addition, compared with other synthetic fibers, polypropylene fiber has the best electrical insulation and heat retention, it has a high electrical resistivity (7×1019 ohms · cm), and low thermal conductivity.

However, the melting point of polypropylene fiber is low (165 ~ 173℃), and the light and heat stability is poor, so the heat resistance and aging resistance of polypropylene fiber are poor, usually by adding heat stabilizer and anti-aging agent to improve its performance. Its hygroscopic and dyeing property is the worst among synthetic fibers, the moisture recovery rate is less than 0.03%, ordinary dyes can not make it colored, so in the spinning of raw materials polypropylene add a certain amount of coloring masterbatch to make the fiber colored.

Hubei Botao Composite Fiber Co., Ltd. mainly produces and sells polypropylene staple fiber, polypropylene staple fiber, PP staple fiber, felt polypropylene staple fiber, flame retardant polypropylene staple fiber, colored polypropylene staple fiber, hot rolled polypropylene staple fiber, hot rolled PP staple fiber and other functional polypropylene staple fiber.
