Introduction of polypropylene fiber

English name of polypropylene fiber: polypropylene fiber
The Chinese trade name of synthetic fiber isotactic polypropylene fiber made from petroleum refining by-product propylene. It is also called polypropylene fiber. The raw materials are abundant, the production process is simple, and the price of the products is lower than that of other synthetic fibers. The physical and mechanical properties of the fiber are: high strength (short fiber 4~6 g / denier, filament 5~8 g / Dan), the wet strength and dry strength are basically the same, the specific gravity is small (0.91), wear resistance and corrosion resistance, etc. The world's annual output of polypropylene fiber has exceeded 1 million tons in 1980.
explain

The famous polypropylene fiber, near flame, flammable, flammable, flammable, slow and black smoke from fire, yellow on the top of the flame, blue in the lower end, oil smell, hard round and shallowly yellowish brown particles after burning, and fragile hand.
It is made from propylene by means of polymerization and melt spinning. Polypropylene began its industrial production in 1957. It is a rising star in synthetic fibers. Because polypropylene has the advantages of simple production process, low price, high strength and relatively low density, polypropylene fiber develops very fast. At present, polypropylene fiber is the fourth largest variety of synthetic fiber, and the lightest fiber in common chemical fiber.
The production of polypropylene includes short fibers, filament and split fiber. Polypropylene fiber is made of polypropylene, which is first made into thin film, and then stretched to form a mesh of raw fiber.
