A detailed introduction to the production process of polypropylene staple fiber!

Polypropylene staple fiber, scientifically known as polypropylene fiber, is a type of fiber made from propylene through polymerization and melt spinning. The following is a detailed introduction to the production process of polypropylene staple fiber!

The principle of the polypropylene staple fiber process is to utilize the properties of addition polymerization reactions, form polymers through the polymerization of propylene, and then shape them through stretching and fiber cutting.

The specific steps include: vaporizing propylene, followed by cooling and vaporization; The obtained propylene is polymerized to obtain polypropylene particles. The obtained polypropylene particles are granulated to obtain polypropylene staple fibers.

Application fields of polypropylene staple fiber

In the textile field, polypropylene staple fibers can be mixed with other fibers to make socks, coats and sportswear, etc. Because it is non-hygroscopic and easy to clean, it is also often used to make waterproof fabrics and geotextiles.

Automobile manufacturing: In the automotive manufacturing industry, polypropylene staple fibers are used as reinforcing materials to enhance the strength and durability of automotive components.

In the field of building materials, polypropylene staple fibers are often used to manufacture concrete reinforcing nets and waterproof materials to enhance the durability and waterproof performance of buildings.

Other fields: Polypropylene staple fibers are also widely used in carpets, decorative fabrics, ropes, industrial filter cloths, packaging materials, civil building fabrics, fishing net fabrics, water hoses and other fields. In addition, polypropylene gauze does not stick to wounds and is often used as a substitute for cotton gauze for applying medicine and as a hygiene product. The flocs made from polypropylene hollow fibers are light, warm and have good elasticity. The new ultrafine polypropylene fibers are an excellent wear-resistant material.

Hubei Botao Synthetic Fiber Co., Ltd. was established in November 2002 and is located in Jingmen High-tech Industrial Development Zone, covering an area of 300,000 square meters. It has five subsidiaries. Our company is a professional manufacturer and seller of polypropylene, polyester, composite fibers, polyethylene fibers, polylactic acid staple fibers and various non-woven fabrics. Our main products are widely used in automotive interiors, geotextiles, carpets, filtration, hygiene, spinning and other industries. By 2024, the company's production capacity of polypropylene staple fiber will be over 150,000 tons and that of polyester staple fiber will be 20,000 tons. After more than 20 years of unremitting efforts in the manufacturing of polypropylene fibers, it has ranked among the top three in terms of sales revenue and market share for five consecutive years. It is currently one of the top three suppliers in terms of the production capacity of polypropylene staple fibers. On December 25, 2024, the company received a letter of approval for listing from the National Equities Exchange and Quotations Company.
