What are the high quality properties of polypropylene staple fiber?

Polypropylene staple fiber with polyamide fiber, polyester fiber light, viscose fiber light contrast has its own advantages, polypropylene staple fiber to polypropylene resin as the main raw material, after melting spinning, drafting, crimping, drying finalize the design cut off, packaging and other processes of color and colorless, regulated number and length of fluffy fiber.

So polypropylene staple fiber has those high quality properties? Light weight, its density is 0.9 ~ 0.92 grams/cubic centimeter, in all synthetic fiber is the lightest, it is 20% lighter than polyamide fiber, 30% lighter than polyester fiber, 40% lighter than viscose fiber; High strength (dry and wet state is the same), good wear resistance and resilience; Anti-microbial, no mold and no moth; Chemical resistance is also better than ordinary synthetic fibers. In addition, compared with other synthetic fibers, polypropylene fiber has the best electrical insulation and warmth retention, with high resistivity (7×1019 ohm · cm) and low thermal conductivity.

However, polypropylene staple fiber melting point is low (165 ~ 173℃), poor light and heat stability, so polypropylene short fiber heat resistance, poor aging resistance, usually take to add heat stabilizer and anti-aging agent to improve its performance. Its hygroscopicity and dyeing property is the worst in the synthetic fiber, moisture regain is less than 0.03%, ordinary dyes can not make it coloring, so in spinning a certain amount of dyeing masterbatch in raw polypropylene to make the fiber coloring.

Hubei Botao Synthetic fiber Co., Ltd. was established in October 2000, specializing in polypropylene staple fiber, polyester staple fiber, composite fiber, poly (lactic acid) staple fiber production, sales, products are mainly used in non-woven fabric, automotive interior, geotextile, carpet, filtration and other industries. The company is located in Jingmen city, Hubei Province, now has six branches, covering a total area of 300,000 square meters. The company is equipped with import fiber production line, fixed assets of more than 100 million yuan, with an annual output of 50,000 tons of polypropylene staple fiber, 20,000 tons of polyester staple fiber, 10,000 tons of composite fiber, and an annual output value of more than 500 million yuan.
