Polypropylene staple fiber with polypropylene resin as the main raw material, through melt spinning, drawing, crimping, drying, cutting, packaging and other processes to produce colored and colorless, specified denier and length of fluffy fiber.

Properties of polypropylene staple fiber:

1, with superior moisture conductivity, flexibility, mesh and carding properties, excellent thermal adhesion

2, light weight, 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.

3, compared with other synthetic fibers, polypropylene short fiber electrical insulation and warmth is the best, its resistivity is very high (7×1019 ohms · cm), the thermal conductivity is very small.

4, high strength, strong crimp elasticity, light weight, low melting point, good surface permeability, acid and alkali resistance and wear resistance are better than other fibers.

Because the polypropylene staple fiber is not hygroscopic and the shrinkage rate is small, the polypropylene fabric has the characteristics of easy washing and quick drying. Polypropylene has poor heat resistance, begins to shrink above 100 ° C, and the temperature can not be too high when washing and dry cleaning, otherwise it will cause shrinkage, deformation, and even melting. The ironing temperature is 90-100 ° C, which requires a wet cloth or steam ironing. Polypropylene has excellent resistance to chemicals, insects and mold, but poor light resistance and climate resistance. Can be pure or blended into a variety of textiles, mainly used in the production of sweaters, sports shirts, socks, competition clothes, underwear, can also be used as wadding and indoor and outdoor carpet.
