There are many kinds of chemical fiber, polypropylene fiber FDY network is a common chemical fiber. How is its performance? Let us understand it together.
Polypropylene varieties are filaments, including undeformed filaments and bulky deformed filaments, short fibers, spun silk, fissured fibers, hollow fibers, shaped fibers, a variety of composite fibers and non-woven fabrics. The main purpose is to produce carpets (including carpet base and suede), decorative fabrics, furniture fabrics, various ropes, strips, fishing nets, oil-absorbing felts, building reinforcing materials, packaging materials and industrial fabrics, such as filter cloths, bag cloths. Wait.
In addition, the use of clothing has become increasingly widespread, and can be mixed with a variety of fibers made of different types of blended fabrics, after knitting can be made into shirts, coats, sportswear, socks and so on. The quilt made of polypropylene hollow fiber is light, warm, and elastic. Polypropylene industrial filter cloth polypropylene does not contain chemical groups that can bind to dyes on macromolecular structures, so dyeing is difficult. The scientific name of polypropylene fiber, near the flame that is melted down, flammable, slowly burning from the fire and black smoke, the flame is yellow on the top, the lower end of the blue, emitting an oil flavor, burned after the ash is a hard round yellow-brown particles, hand crush brittle . The melt coloring method is usually adopted. The pigment preparation and the polypropylene polymer are uniformly mixed in the screw extruder, and the color fastness of the colored fiber is obtained after melt spinning. Another method is to copolymerize or graft copolymerize with acrylic acid, acrylonitrile, vinylpyridine, etc. to introduce a polar group that can bind to the dye on the polymer macromolecule, and then dye it directly by conventional methods. In the production of polypropylene, it is often necessary to add various additives to improve the dyeing, lightfastness and flame resistance.
Because of its stable performance and strong moldability, polypropylene FDY network wire has been widely used in our lives to integrate into our lives.
