Polypropylene fiber line, close to the flame that is melting, flammable, burning slowly from the fire and black smoke, flame top yellow, blue bottom, emitting a taste of oil, burned ashes for hard round light brown particles, hand twist fragile.
It is from propylene as raw material by polymerization, melt spinning fiber. Polypropylene in 1957 officially began industrial production, is a rising star of synthetic fibers. As a result of polypropylene production process is simple, inexpensive products, high strength, the relative density of light, so the development of polypropylene very quickly. At present, polypropylene is the fourth largest synthetic fiber, is the most common chemical fiber in the lightest fiber.
Polypropylene varieties are filament (including non-deformed filaments and bulky deformation of filament), short fibers, bristles, split fiber, hollow fiber, shaped fibers, all kinds of composite fibers and non-woven fabrics. The main purpose is the production of carpets (including carpets and suede), Zhuang Shibu, furniture fabrics, all kinds of rope, strip, fishing nets, oil-absorbing carpets, building materials, packaging materials and industrial fabrics such as cloth, Wait. In addition, the application of clothing is also becoming increasingly widespread, with a variety of fiber blends made of different types of blended fabric, after knitting can be made into shirts, jackets, sportswear, socks and so on. Made from polypropylene fiber hollow fiber is, light, warm, good elasticity. & Lt; / RTI & gt; Polypropylene in 1957 officially began industrial production, is a rising star of synthetic fibers.
