Purpose of polypropylene staple fiber: Polypropylene has excellent comprehensive properties and a wide range of applications.

Properties of polypropylene staple fiber: Polypropylene is a highly crystalline (up to 95% crystallinity) thermoplastic resin with regular configuration. The product is a natural colored granular material, non-toxic, odorless, odorless, and lightweight polymer with a density of 0 90-0.91g/Cm3, is the lightest type of general plastic. Good rigidity, wear resistance, high hardness, and good high-temperature impact resistance (but sharply decreases below -5 ℃). Strong resistance to repeated folding. Good heat resistance, with a heat deformation temperature of 114 ℃, a Vicat softening point of>140 ℃, a melting point of 164-167 ℃, and a continuous use temperature of 110-120 ℃. Under no load, the use temperature can reach 150 ℃. It is the only product among general plastics that can boil in water and be disinfected at 130 ℃. Good chemical stability, except for strong oxidizing media, it does not interact with most chemicals. The stability of water is particularly prominent, not only insoluble in water, but also almost non absorbent. The water absorption rate after 24 hours in water is only 0 01%. Excellent electrical insulation performance, good voltage and arc resistance. Its main drawback is poor light resistance and easy aging; Poor cold resistance, poor low-temperature impact strength, poor toughness, high static electricity, poor dyeing, printing, and adhesion, but can be improved by adding additives and co mixing copolymerization.

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 short fibers. The products are mainly used in industries such as non-woven fabrics, automotive interiors, geotextiles, carpets, and filtration. The company is located in Jingmen City, Hubei Province, and currently has six branches, covering a total area of 300000 square meters. The company is equipped with an imported fiber production line, with fixed assets exceeding 100 million yuan. It produces 50000 tons of polypropylene short fibers, 20000 tons of polyester short fibers, and 10000 tons of composite fibers annually, with an annual output value exceeding 500 million yuan.

The company adheres to technological innovation as the foundation, introduces new technological talents, cooperates with universities and colleges to develop and create a high-end Botao brand. The polypropylene short fibers used for automotive interiors and high-speed rail geotextiles that closely follow market demand have filled the market gap. The company currently has more than 280 employees, including 8 engineers and more than 30 other technical personnel. With strong technical strength, it has a strict quality inspection system and independent research and development, production, and marketing capabilities. It is a leading enterprise in the Chinese polypropylene industry and has participated in drafting and formulating the "Polypropylene Short Fiber" industry standard. It is the vice chairman unit of the Polypropylene Branch of the China Chemical Fiber Association.
