What are the advantages of the Polypropylene staple fiber produced by Hubei Botao Synthetic Fiber Co., LTD.? Let's take a look together today!

We specialize in the production of Polypropylene staple fibers, colored polypropylene staple fiber, flame-retardant polypropylene staple fiber and polypropylene staple fiber for felt. The company's main product is polypropylene staple fiber: specifications 0.3-110dt, lengths 5-150mm, annual output 30,000 tons, and complete colors.

Polypropylene staple fibers are made from polypropylene resin as the main raw material, and are produced through processes such as melt spinning, drawing, curling, drying, shaping, cutting, and packaging into fluffy fibers of color and colorless, with specified denier numbers and lengths.

Polypropylene staple fibers are light in weight, with a density of 0.9 to 0.92 grams per cubic centimeter. Among all synthetic fibers, they are relatively light. They are 20% lighter than polyamide fibers, 30% lighter than polyester fibers, and 40% lighter than viscose fibers. High strength (the same in dry and wet states), good wear resistance and resilience; Antimicrobial, mold-free and moth-proof; Its chemical resistance is also superior to that of common synthetic fibers. In addition, compared with other synthetic fibers, polypropylene fibers have good electrical insulation and thermal insulation properties. Their resistivity is very high (7×1019 ohms · cm), and their thermal conductivity is very small.

However, the melting point of Polypropylene staple fibers is low (165-173℃), and they have poor light and heat stability. Therefore, the heat resistance and aging resistance of polypropylene staple fibers are poor. Usually, heat stabilizers and anti-aging agents are added to improve their performance. Its moisture absorption and dyeability are among the poorest in synthetic fibers, with a moisture regain of less than 0.03%. Common dyes cannot color it, so in the spinning process, a certain amount of coloring masterbatch is often added to the raw material polypropylene to color the fibers.

Hubei Botao Synthetic Fiber Co., Ltd., Ltd. mainly produces and sells various functional polypropylene staple fibers such as 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, and hot-rolled PP staple fiber.
