Polypropylene staple fiber has the advantages of light weight, high strength, wear resistance, environmental protection, easy to clean and so on. This kind of polypropylene staple fiber is known as the polypropylene staple fiber of Wei material. Polypropylene staple fiber is suitable for making all kinds of needled non-woven fabric, non-woven fabric, decorative non-woven fabric and so on.

Polypropylene staple fiber can also be used in geosynthetic materials, such as geotextiles, geomesh, etc. For nonwoven filter materials; Medical and health materials; Agricultural, clothing, home decorative cloth and so on a variety of different industries.

Polypropylene staple fiber light, its density is 0.9 ~ 0.92 grams/cubic centimeter, in all synthetic fibers is lighter, it is 20% lighter than polyamide fiber, 30% lighter than polyester fiber, 40% lighter than viscose fiber; High strength (dry and wet state is the same), good wear resistance and resilience; Anti-microbial, no mildew, no decay; Chemical resistance is also better than the general synthetic fiber. In addition, compared with other synthetic fibers, polypropylene fiber has the best electrical insulation and heat retention, it has a high electrical resistivity (7×1019 ohms · cm), and a small thermal conductivity.

However, the melting point of Polypropylene staple fiber is low (165 ~ 173℃), and the stability of light and heat is poor, so the heat resistance and aging resistance of polypropylene fiber are poor. Usually, heat stabilizer and anti-aging agent are added to improve its performance. Its hygroscopic and dyeing properties are the worst in the synthetic fiber, the moisture recovery rate is less than 0.03%, ordinary dyes can not make it colored, so in the spinning process of raw material polypropylene to add a certain amount of coloring masterbatch to make the fiber colored.
