The characteristics of polypropylene staple fiber: polypropylene staple fiber has low density, light weight, and can float on the water; polypropylene yarn has high strength and strong tensile strength; polypropylene staple fiber has certain acid and alkali resistance and corrosion resistance, even if soaked Don't worry about it in sea water; polypropylene staple fiber has low hygroscopicity and almost no moisture absorption; polypropylene staple fiber is an environmentally friendly and pollution-free product.

Polypropylene staple fiber is made of polypropylene through the processes of melting, drawing, spinning and cutting. In the process of making polypropylene staple fibers, functional masterbatches, such as anti-aging masterbatches, flame retardant masterbatches, etc., can be added as needed to increase the performance of polypropylene staple fibers. Polypropylene staple fiber for felt is a polypropylene staple fiber specially used for making felt, which is used for filter material.

Polypropylene staple fibers are mainly used in needle-punched carpets, automotive interiors, non-woven fabrics, ropes, decorative materials, medical and sanitary products, etc. Short fiber is also called cut fiber. Chemical fiber long fiber bundles are cut or broken into fibers corresponding to various natural fiber lengths. Natural fibers such as whiskers and asbestos can also be used. Short fiber limit, the length is generally 35 ~ 150mm. According to the specifications of natural fibers, it can be divided into short fibers such as cotton type, wool type, carpet type and medium and long type. They can be spun purely or blended with natural or other fibers in varying proportions to make sliver, fabric and felt. For example, general-grade pitch carbon fiber is cut into 150mm long, 15μm in diameter, carbon fiber with a strength of 800MPa and a modulus of 41GPa, and mixed with phenolic carbon fiber (length 70mm, strength 200MPa, diameter 14μm) in a ratio of 8:2 to obtain Stable and uniform sliver. Woven into various shapes of fabrics or chopped fibers for reinforcement of composite materials such as cement and aluminum alloys.

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 staple fibers. and other industries. The company is located in Jingmen City, Hubei Province, and now has six branches with a total area of 300,000 square meters. The company is equipped with imported fiber production lines, with fixed assets exceeding 100 million yuan, with an annual output of 50,000 tons of polypropylene staple fibers, 20,000 tons of polyester staple fibers, and 10,000 tons of composite fibers, with an annual output value exceeding 500 million yuan.

The company adheres to the basis of technological innovation, introduces new technical talents, cooperates with universities and colleges in research and development, and builds a high-end BOTO brand.
