Polypropylene staple fiber is widely used in geotextile, textile, filter cloth, cool cloth, all kinds of non-woven fabrics, automotive interior, spinning, carpet, engineering materials, composite materials, filling materials, sound insulation, felt products and other industries.

　　Polypropylene staple fiber (Polypropylene staple fiber), also known as PP fiber or polypropylene. Polypropylene staple fiber is made from propylene by one step short-range spinning process. Polypropylene began industrial production in 1957, because the raw material only needs propylene, the source is relatively rich, cheap, and the production process is simple, and it is currently a relatively cheap synthetic fiber. Polypropylene has good performance and rapid development, and its output is second only to polyester, nylon, acrylic and so on in the world.

　　Do you understand the characteristics and uses of polypropylene staple fiber?

　　Relative density: polypropylene is the relatively small density of all synthetic fibers, about 0.91g/cm3, so it is extremely light in weight, and the area covered by the unit weight of the fiber is large.

　　Strength: The strength of polypropylene is similar to that of high-strength varieties of polyester and nylon in synthetic fibers, but the strength hardly changes in the wet state, which is better than nylon.

　　Wear resistance and corrosion resistance: the flat wear resistance of polypropylene is second only to that of nylon, but the wear resistance is slightly worse. Corrosion resistance: It has significant stability to inorganic acid and alkali.

　　Hygroscopicity and dyeability: polypropylene is almost non-hygroscopicity, its moisture regain rate is less than 0.03%, the shrinkage rate of fabric is small, and fine denier polypropylene has a strong core absorption effect. Dyeing fastness is poor, ordinary fuel can not make it dyeing.

　　Electrical insulation and heat preservation: polypropylene has a high electrical resistivity (7× 10ω.cm) and a small thermal conductivity. Compared with other chemical fibers, polypropylene has good electrical insulation and heat preservation, but it is easy to generate static electricity during processing.

　　Heat resistance and aging resistance: the melting point of polypropylene is low (165~173 ° C), and the stability of light and heat is poor, so the heat resistance and aging resistance of polypropylene are poor and not resistant to ironing. However, the anti-aging properties can be improved by adding anti-aging agents during spinning.

　　In addition, polypropylene, like other synthetic fibers, is not easy to mold, rot, not afraid of insects.

　　Hubei Botao Synthetic Fiber Co., Ltd. was founded in October 2000, located in Jingmen City, Hubei Province, specializing in the production and sales of polypropylene, polyester, composite fiber, polylactic acid staple fiber, the products are mainly used in non-woven fabrics, automotive interior, geotextiles, carpets, filtration and other industries.

　　Hubei Botao Synthetic Fiber Co., Ltd. has introduced a number of imported fiber production lines, with fixed assets exceeding 300 million yuan, an annual output of 100,000 tons of polypropylene staple fiber, 20,000 tons of polyester staple fiber, 10,000 tons of composite fiber, and an annual output value of over 800 million yuan. Focusing on the field of synthetic fiber for more than 20 years, Botao synthetic fiber has obtained excellent market results and extensive honors with the mentality of excellence and integrity development. In 2014, as the vice president unit of the polypropylene Branch of China Chemical Fiber Association, participated in the drafting and formulation of the "polypropylene staple fiber" industry standard; In 2018, it won the invisible champion in the pillar industry segmentation field of Hubei Province Science and Technology Small Giant, which is a provincial specialized and special new small giant enterprise......
