Lightweight, with a density of 0.9-0.92 grams per cubic centimeter, it is the lighter among all synthetic fibers. It is 20% lighter than polyamide fibers, 30% lighter than polyester fibers, and 40% lighter than viscose fibers; High strength (same in dry and wet conditions), good wear resistance and resilience; Anti microbial, non mold and non decay; Chemical resistance is also superior to general synthetic fibers. In addition, compared to other synthetic fibers, polypropylene fiber has the best electrical insulation and warmth retention, with a high electrical resistivity (7 × 1019 ohms per centimeter, with a very low thermal conductivity.

However, the melting point of polypropylene short fibers is low (165-173 ℃), and their stability to light and heat is poor. Therefore, the heat resistance and aging resistance of polypropylene fibers are poor. Usually, adding heat stabilizers and anti-aging agents is used to improve their performance. Its moisture absorption and dyeing properties are the worst among synthetic fibers, with a moisture regain of less than 0.03%. Ordinary dyes cannot color it, so a certain amount of coloring masterbatch is often added to the raw material polypropylene during spinning to color the fibers.

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 over 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 industry standard "Polypropylene Short Fiber". It is the vice president unit of the Polypropylene Branch of the China Chemical Fiber Association.
