Polypropylene staple fiber has its own advantages compared with polyamide fiber, polyester fiber, light viscose fiber, etc. Polypropylene staple fiber uses polypropylene resin as the main raw material, which is melt-spinning, drafting, crimping, and drying to shape and cut. Colored and colorless, fluffy fibers with specified denier and length.

  So what are the high-quality properties of polypropylene staple fiber? Lightweight, its density is 0.9~0.92 g/cm3, which is the lightest among all synthetic fibers. It is 20% lighter than polyamide fiber, 30% lighter than polyester fiber, and 40% lighter than viscose fiber; High (the same in dry state and wet state), good abrasion resistance and resilience; anti-microbial, no mildew and no moth; chemical resistance is also better than general synthetic fibers. In addition, compared with other synthetic fibers, polypropylene fiber has the best electrical insulation and warmth retention. It has a high electrical resistivity (7×1019 ohm·cm) and a small thermal conductivity.

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