Light weight, its density of 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 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. In addition, compared with other synthetic fibers, polypropylene fiber has the best electrical insulation and heating properties, its resistivity is very high (7×1019 ohms · cm), and its thermal conductivity is very small.

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

Hubei Botao Synthetic Fiber Co., Ltd. was established in October 2000, specializing in the production and sales of polypropylene, polyester, composite fiber, polylactic acid staple fiber, the products are mainly used in non-woven fabrics, automotive interior, geotextiles, carpets, filtration and other industries. The company is located in Jingmen City, Hubei Province, now has six branches, covering a total area of 300,000 square meters. The company is equipped with imported fiber production line, fixed assets of more than 100 million yuan, an annual output of 50,000 tons of polypropylene staple fiber, 20,000 tons of polyester staple fiber, 10,000 tons of composite fiber, the annual output value of more than 500 million yuan.

The company insists on technological innovation as the basis, the introduction of new technical talents, cooperation with colleges and universities research and development, to create high-end Botao brand, keep up with the market demand research and development of automotive interior, high-speed rail geotextile polypropylene staple fiber to fill the market gap. The company has more than 280 employees, including 8 engineers, more than 30 other technical personnel, strong technical force, with strict quality testing system and independent research and development, production and marketing capabilities, is a leading enterprise in China's polypropylene industry, participated in the drafting of the "polypropylene staple fiber" industry standard, is the China Chemical Fiber Association polypropylene branch vice president unit.
