Polypropylene staple fiber is a synthetic fiber processed from polypropylene as raw material through one-step short-process spinning technology. Since its industrial production was realized in 1957, it has become one of the synthetic fiber varieties with extremely high cost performance, thanks to its advantages such as easy availability of raw materials, low cost and simple process. Its production scale ranks among the top in the global synthetic fiber field.

This product can have its performance improved by adding functional masterbatches (such as anti-aging agents, flame retardants, etc.). Among them, the special Polypropylene staple fiber  for felt is the preferred raw material for felt used as a filter material. Its notable features include: being lighter than water in specific gravity and having excellent floating performance; Its high strength property endows it with excellent tensile resistance. It has outstanding chemical corrosion resistance and is suitable for Marine environments. Hydrophobic property with nearly zero moisture absorption; It also meets environmental protection requirements.

Hubei Botao Synthetic Fiber Co., Ltd. was founded in November 2002 and is located in Jingmen National High-tech Zone, covering an area of 300,000 square meters. It has five wholly-owned subsidiaries under its umbrella. As a professional manufacturer of fiber materials, the company's product line covers polypropylene, polyester, composite fibers, polyethylene fibers and polylactic acid staple fibers, etc. It also offers non-woven fabric manufacturing services. The products are widely used in automotive interiors, geotechnical building materials, flooring materials, filter media, hygiene materials and textiles, among other fields. By 2024, the company has formed an annual production capacity of 150,000 tons of Polypropylene staple fiber  and 20,000 tons of polyester staple fiber. With over two decades of professional accumulation, the enterprise has maintained a market position among the top three in industry sales for five consecutive years and has now become a core supplier ranking among the top three in domestic Polypropylene staple fiber  production capacity. In December 2024, the company successfully obtained the listing license on the National Equities Exchange and Quotations System.
