Hubei Botao Synthetic Fiber Co., Ltd. specializes in the production of polypropylene staple fiber, polypropylene staple fiber, colored polypropylene staple fiber, flame retardant polypropylene staple fiber and polypropylene staple fiber for felt. The company's main products are polypropylene staple fiber: specification 0.3-110dt, length 5-150mm, annual output of 30,000 tons, complete color. Polypropylene staple fiber is mainly used for: non-woven fabrics for sanitary materials (such as women's sanitary napkins, baby diapers, medical masks, clothes and hats, etc.), needle punched carpets, electric blanket fabrics, filter fabrics, geotextiles, automotive decorative fabrics, clothing linings, artificial fur, wool, yarn, hygiene products hot-rolled non-woven fabrics, polypropylene spinning, interior parts, speaker fabrics, spinning yarns, filter materials, adsorption materials, cigarette filters, ropes, wool strips, filter materials and other fields.

The above polypropylene staple fiber products can be added according to user needs to add anti-aging agents, flame retardants, anti-ultraviolet agents, etc. to increase the characteristics of polypropylene staple fiber.

So what are the premium properties of polypropylene staple fiber? Lightweight, its density is 0.9~0.92 g / cubic centimeter, the lightest among all synthetic fibers, it is 20% lighter than polyamide fiber, 30% lighter than polyester fiber, 40% lighter than viscose fiber; High strength (the same in dry and wet state), good wear resistance and resilience; Anti-microbial, not mildew and moth; Chemical resistance is also superior to that of general synthetic fibers. In addition, polypropylene fiber has the best electrical insulation and warmth compared to other synthetic fibers, its resistivity is very high (7×1019 ohm·cm), and the thermal conductivity is small.

However, the melting point of polypropylene staple fiber is low (165~173 °C), and the stability of light and heat is poor, so polypropylene staple fiber has poor heat resistance and aging resistance, and it is usually taken to add heat stabilizers and anti-aging agents to improve its performance. Its hygroscopicity and dyeability are the worst of synthetic fibers, moisture regain is less than 0.03%, ordinary dyes can not make it colored, so in the spinning of more use in the raw material polypropylene to add a certain amount of coloring masterbatch to color the fiber.

Hubei Botao Synthetic Fiber Co., Ltd. mainly produces and sells polypropylene staple fiber, polypropylene staple fiber, PP staple fiber, polypropylene staple fiber for felt, flame retardant polypropylene staple fiber, colored polypropylene staple fiber, hot-rolled polypropylene staple fiber, hot-rolled PP staple fiber and other functional polypropylene staple fiber.
