What are the properties of polypropylene short fibers? It is light, with a density of 0.9-0.92g/cm3, which is very light among all Synthetic fiber, 20% lighter than nylon, 30% lighter than polyester, and 40% lighter than viscose fiber; High strength (dry and wet), good wear resistance and resilience; Antibacterial, mold free and moth free; Chemical resistance is also better than general Synthetic fiber. In addition, compared with other Synthetic fiber, polypropylene fibers have high electrical insulation, warmth retention and resistivity (7 × 1019 ohm · cm), with low thermal conductivity. However, polypropylene short fibers have a low melting point (165-173 ℃) and poor photothermal stability, resulting in poor heat resistance and aging resistance of polypropylene fibers. Heat stabilizer and anti-aging agent are usually added to improve its performance. Its hygroscopicity and dyeability are medium poor for Synthetic fiber, moisture regain is less than 0.03%, and it cannot be dyed by ordinary dyes. Staining.

Production and sales of polypropylene, polyester, composite fibers, and polylactic acid short fibers. The products are mainly used in non-woven fabric, automotive interior, Geotextile, carpet, filtration and other industries.

The Chinese trade name for synthetic isotactic polypropylene fibers made from propylene, a byproduct of petroleum refining. Also known as polypropylene fiber. Data shows that the downstream industry of polypropylene fiber in the future will enter a new cycle of prosperity, which will lead to an expansion of demand in the polypropylene fiber market.

The Chinese trade name for synthetic isotactic polypropylene fibers made from propylene, a byproduct of petroleum refining. Also known as polypropylene fiber. The raw materials are abundant, the production process is simple, and the product price is relatively lower than other Synthetic fiber. The physical and mechanical properties of fibers are: high strength (4-6g/den for short fibers and 5-8g/den for long fibers), basically the same dry and wet strength, small specific gravity (0.91), wear and corrosion resistance, etc. In 1980, the annual production of polypropylene fibers in the world exceeded 1 million tons.

Polypropylene short fibers are made from polypropylene resin as the main raw material, and undergo processes such as melt spinning, drawing, curling, drying, shaping, cutting, and packaging to produce colored, colorless, fluffy fibers of specified size and length. Due to the non moisture absorption and low shrinkage of polypropylene short fibers, polypropylene fabrics have the characteristics of easy washing and quick drying. Polypropylene has poor heat resistance and begins to contract above 100 ℃. The temperature should not be too high during washing and dry cleaning, as it may cause shrinkage, deformation, or even melting. The ironing temperature is between 90-100 ° C and requires a layer of damp cloth or steam ironing. Polypropylene has good resistance to chemicals, moths, and mold.

Hubei Botao Synthetic Fiber Co., Ltd., founded in October 2000 and located in Jingmen City, Hubei Province, is specialized in the production and sales of polypropylene fiber, polyester fiber, composite fiber and polylactic acid staple fiber.
