What are the high-quality properties of polypropylene staple fiber?

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 fibers have a low melting point (165-173 °C) and poor light and thermal stability, so polypropylene staple fibers have poor heat resistance and aging resistance. Usually, heat stabilizers and anti-aging agents are added to improve their 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.

Hubei Botao Synthetic Fiber Co., Ltd. was established in October 2000, specializing in the production and sales of polypropylene, polyester, composite fibers, and polylactic acid staple fibers. and other industries. The company is located in Jingmen City, Hubei Province, and now has six branches with a total area of 300,000 square meters. The company is equipped with imported fiber production lines, with fixed assets exceeding 100 million yuan, with an annual output of 50,000 tons of polypropylene staple fibers, 20,000 tons of polyester staple fibers, and 10,000 tons of composite fibers, with an annual output value exceeding 500 million yuan.
