Why can PP high-strength yarn be called the strength of synthetic fiber?

PP high-strength yarn is a rising star in synthetic fiber, which is obtained by polymerization and melt spinning of propylene as raw material. Because of its simple production process, low cost, high strength and relatively low density, it has developed rapidly. It is now the fourth largest variety of synthetic fibers and the lightest of the most common chemical fibers. Its varieties include filament, short fiber, silk, membrane fiber, hollow fiber, shaped fiber, various composite fibers and non-woven fabric. The main purposes are to make carpets, decorative fabrics, furniture fabrics, ropes, strips, fishing nets, oil absorbing felts, building reinforcements, packaging materials and industrial fabrics, such as filter cloth, bag cloth and so on. In addition, it is also widely used in clothing. It can be blended with various fibers to make different types of blended fabrics. After knitting, it can be made into shirts, outerwear, sportswear, socks and so on. The floc made of its hollow fiber is light in weight, warm and has good elasticity.

PP high-strength yarn  do not contain chemical groups that bind to dyes in the macromolecular structure, so dyeing is difficult. The pigment preparation and the polypropylene polymer are uniformly mixed in a screw extruder by a melt coloring method, and melt-spun to obtain a colored fiber having high color fastness. Another method is copolymerization or graft copolymerization with acrylic acid, acrylonitrile, vinyl pyridine, etc., to introduce a polar group capable of binding with a dye on a polymer macromolecule, and directly dyeing by a conventional method. It is often necessary to add various additives during the production process to improve dyeability, light resistance and flame resistance. Its scientific name is polypropylene fiber, which is melted near the flame, is flammable, burns slowly from the fire and emits black smoke. The upper end of the flame is yellow, the lower end is blue, and the oil smell is emitted. After burning, the ash is hard round, light yellow and brown particles, handcuffs. fragile.
