Hubei Botao Synthetic Fiber Co., Ltd. specializes in producing polypropylene short fibers, polypropylene short fibers, colored polypropylene short fibers, flame retardant polypropylene short fibers, and polypropylene short fibers for felt. The company's main product is polypropylene short fiber: specifications 0.3-110dt, length 5-150mm, annual production of 30000 tons, with complete colors. Polypropylene staple fibers are mainly used for: non-woven fabrics for sanitary materials (such as women's sanitary napkins, baby diapers, medical masks, clothing, etc.), needle punched carpets, electric blanket fabrics, filter fabrics, geotextiles, automotive decorative fabrics, clothing linings, artificial fur, wool, yarn spinning, hot rolled non-woven fabrics for sanitary products, polypropylene spinning, interior accessories, speaker fabrics, spinning wool, filter materials, adsorption materials, cigarette filter tips, ropes, wool tops Filter materials and other fields.

The above polypropylene staple fiber products can be added with anti-aging agent, flame retardant, anti UV agent, etc. according to user needs to increase the properties of polypropylene staple fiber.

So what are the high-quality properties of polypropylene short fibers? Lightweight, with a density of 0.9-0.92 grams per cubic centimeter, it is the lightest of all synthetic fibers. It is 20% lighter than polyamide fibers, 30% lighter than polyester fibers, and 40% lighter than viscose fibers; High strength (same in dry and wet conditions), good wear resistance and resilience; Anti microbial, non mold and non decay; Chemical resistance is also superior to general synthetic fibers. In addition, compared to other synthetic fibers, polypropylene fiber has the best electrical insulation and warmth retention, with a high electrical resistivity (7 × 1019 ohms per centimeter, with a very low thermal conductivity.

However, the melting point of polypropylene short fibers is low (165-173 ℃), and their stability to light and heat is poor. Therefore, the heat resistance and aging resistance of polypropylene short fibers are poor. Usually, adding heat stabilizers and anti-aging agents is used to improve their performance. Its moisture absorption and dyeing properties are the worst among synthetic fibers, with a moisture regain of less than 0.03%. Ordinary dyes cannot color it, so a certain amount of coloring masterbatch is often added to the raw material polypropylene during spinning to color the fibers.

Hubei Botao Synthetic Fiber Co., Ltd. mainly produces and sells various functional polypropylene short fibers such as polypropylene short fibers, polypropylene short fibers, PP short fibers, felt polypropylene short fibers, flame retardant polypropylene short fibers, colored polypropylene short fibers, hot-rolled polypropylene short fibers, and hot-rolled PP short fibers.
