The polypropylene staple fiber is made of polypropylene resin as the main raw material, which is formed into a fluffy and colorless, defined, and the length of fluffy fibers are made by melt spinning, drafting, curling, drying stereotype, packaging and other processes.

The  polypropylene staple fiber has a lot of excellent performance, mainly reflected in the following four aspects:

First, superior humidification, flexibility, surfing, and superphractical, thermally bonded

The second polypropylene staple fiber is light, its density is 0.9 ~ 0.92 g / cubic centimeter, which is the lightest in all synthetic fibers, which is 2% percent than the polyamide fiber, 30% percent of polyester fibers, than adhesive fiber. Lighter 40%; high strength (same as in dampness), abrasion resistance and back elasticity; anti-microorganisms, non-mildew; chemical resistance is also superior to general synthetic fibers.

Third, compared with other synthetic fibers, the electrical insulation and warmth of polypropylene fibers is preferably, its resistivity is high (7 × 1019 ohm, cm), and the thermal conductivity is small.

Fourth, high strength, strong curling elasticity, light weight, low melting point, good surface permeability, acid and alkali-resistant wear resistance is better than other fibers.

The above four points are some of the properties of  polypropylene staple fibers.
