PP staple fiber is 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.

Characteristics of PP staple fiber

1, PP short fiber density is small

Polypropylene is the relatively small density of all synthetic fibers, about 0.91g/cm3, so it is very light and can cover a large area per unit weight of fiber.

2, PP short fiber strength is high

The strength of polypropylene is similar to that of high-strength polyester and nylon in synthetic fibers, but the strength hardly changes in the wet state, which is better than nylon.

3. PP staple fiber is not only wear-resistant but also corrosion-resistant

The flat wear resistance of polypropylene is second only to that of nylon, but the bending wear resistance is slightly worse. Corrosion resistance: It has significant stability to inorganic acid and alkali.

4. PP staple fiber is almost non-hygroscopic

Polypropylene is almost non-hygratic, its moisture regain rate is less than 0.03%, the shrinkage rate of the fabric is small, and the fine denier polypropylene has a strong core suction effect.

5, PP short fiber electrical edge and warmth is very good

Polypropylene has high electrical resistivity (7× 10ω.cm), small thermal conductivity, and good electrical insulation and warmth retention compared with other chemical fibers, but it is easy to produce static electricity during processing.

6, PP short fiber aging resistance

The melting point of polypropylene is low (165~173 ° C), and the stability of light and heat is poor, so the heat resistance and aging resistance of polypropylene are poor and not resistant to ironing. However, the anti-aging properties can be improved by adding anti-aging agents during spinning.
