Polypropylene staple fiber will be used in all walks of life, widely used in geotextiles, non-woven fabrics, nonwovens, wool, polypropylene yarn, carpet and other textile industries. PP polypropylene staple fiber is polypropylene resin as the main raw material, through melt spinning, drawing, crimping, drying, shaping, cutting, packaging into a specified size and length of the fluffy fiber.

Characteristics of polypropylene staple fiber:

1. Low density

In all synthetic fibers, the density is relatively low, about 0.91g/cm3, so its weight is very light, and the area covered by each unit weight of fiber is large.

2. Polypropylene staple fiber has high strength

The strength of polypropylene staple fiber is similar to that of polyester, nylon and other high strength synthetic fibers, but the wet strength is almost unchanged, which is better than nylon.

3. Polypropylene staple fiber is not only wear-resistant, but also corrosion-resistant

The flat wear resistance is second only to nylon, but the bending wear resistance is slightly worse. Corrosion resistance: It has obvious stability to inorganic acids and bases.

4. Almost no moisture absorption.

Polypropylene is almost non-hygroscopic, the moisture recovery rate is less than 0.03%, the shrinkage rate of the fabric is small, and the core absorption effect of fine denier polypropylene is strong.

5. Excellent electrical conductivity and heat insulation

Polypropylene staple fiber has high electrical resistivity (710cm) and low thermal conductivity. Compared with other chemical fibers, polypropylene has good electrical insulation and heat insulation, but it is easy to generate static electricity during processing.

6. Anti-aging

The melting point of ene is low (165~173), and the stability to light and heat is poor. So the heat resistance and aging resistance is poor, not resistant to ironing. However, adding antioxidant in the spinning process can improve the anti-aging property.

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. The company has introduced a number of imported fiber production lines, with fixed assets of more than 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.
