Compared with polyamide fibers, polyester fibers, and viscose fibers, polypropylene staple fibers have their own advantages and characteristics. Polypropylene staple fibers use polypropylene resin as the main raw material. Colored and colorless fluffy fibers with specified denier and length in the process of packaging, packaging and other processes.

So what are the high-quality properties of polypropylene staple fiber? Lightweight, its density is 0.9-0.92 g/cm3, the lightest among all synthetic fibers, it is 20% lighter than polyamide fiber, 30% lighter than polyester fiber, and 40% lighter than viscose fiber; strength High (dry state and wet state), good abrasion resistance and resilience; anti-microbial, no mildew or 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, so 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, the moisture regain is less than 0.03%, and ordinary dyes can not make it color. coloring.

Polypropylene staple fiberuses polypropylene resin as the main raw material, and 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.

Product performance of polypropylene staple fiber:

1. It has excellent moisture conductivity, flexibility, web-forming and carding properties, and excellent thermal adhesion.

2. High strength, strong curling elasticity, light weight, low melting point, good surface permeability, acid and alkali resistance and wear resistance are better than other fibers

Polypropylene staple fibers are mainly used in needle-punched carpets, automotive interiors, non-woven fabrics, ropes, decorative materials, medical and sanitary products, etc.
