What are the advantages of polypropylene staple fiber produced by Hubei Botao Synthetic Fiber Co., Ltd.? Let’s take a look today!

We specialize in the production of polypropylene staple fiber, polypropylene staple fiber, colored polypropylene staple fiber, flame-retardant polypropylene staple fiber and polypropylene staple fiber for felt. The company's main product is polypropylene staple fiber: specifications 0.3-110dt, length 5-150mm, annual output 30,000 tons, complete colors.

Polypropylene staple fiber uses polypropylene resin as the main raw material. It is made into colored and colorless fluffy fibers with specified denier and length through melt spinning, drafting, crimping, drying, shaping, cutting, packaging and other processes.

Polypropylene staple fiber is light in weight, with a density of 0.9 to 0.92 grams/cubic centimeter. It is lighter among all synthetic fibers. It is 20% lighter than polyamide fiber, 30% lighter than polyester fiber, and 40% lighter than viscose fiber. %; high strength (the same in dry and wet states), good abrasion resistance and resilience; anti-microbial, mildew and moth-free; chemical resistance is also better than ordinary synthetic fibers. In addition, compared with other synthetic fibers, polypropylene fiber has good electrical insulation and warmth retention properties, its resistivity is very high (7×1019 ohm·cm), and its thermal conductivity is very small.

However, polypropylene short fiber has a low melting point (165-173°C) and poor light and thermal stability. Therefore, polypropylene short fiber has poor heat resistance and aging resistance. Heat stabilizers and anti-aging agents are usually added to improve its performance. Its hygroscopicity and dyeability are poor among synthetic fibers, and its moisture regain is less than 0.03%. Ordinary dyes cannot color it. Therefore, during spinning, a certain amount of coloring masterbatch is often added to the raw material polypropylene to make the fiber Coloring.

Hubei Botao Synthetic Fiber Co., Ltd. mainly produces and sells polypropylene staple fiber, polypropylene staple fiber, PP staple fiber, polypropylene staple fiber for felt, flame-retardant polypropylene staple fiber, colored polypropylene staple fiber, hot-rolled polypropylene staple fiber, hot-rolled PP Various functional polypropylene staple fibers such as staple fiber.
