Nowadays, there are many chemical products on the market, and most of them are harmful to our body. Therefore, we must understand some of the chemical properties of these products. Now let's take a look at the chemical properties of polypropylene high-strength yarn!

High-strength polypropylene yarn is a rising star in the synthetic fiber, propylene as raw materials by polymerization, melt spinning system. Because of its production process is simple, inexpensive products, high strength, the relative density of light advantages, so the rapid development. It is now the fourth largest variety of synthetic fibers and is the lightest fiber in common chemical fibers. Its varieties are filament, short fiber, bristle, split membrane, hollow fiber, shaped fiber, all kinds of composite fibers and non-woven fabrics. The main purpose is to make carpets, decorative fabrics, furniture fabrics, ropes, straps, fishing nets, linoleum, building reinforcements, packaging materials and industrial fabrics, such as filter cloth, sackcloth and so on. In addition, the application of clothing is also increasingly widespread, with a variety of fiber blends made of different types of blended fabrics, after knitting can be made into shirts, outerwear, sportswear, socks and so on. Made of its hollow fibers, the quilt is light, warm and elastic.

Polypropylene high-strength yarn in the molecular structure does not contain chemical groups can be combined with the dye, so dyeing more difficult. Usually melt-color method, the pigment preparation and polypropylene polymer in the screw extruder evenly mixed, after melt spinning to get color fastness to color fiber. Another method is acrylic acid, acrylonitrile, vinyl pyridine copolymerization or graft copolymerization, the polymer macromolecules can be combined with the dye polar groups, and then directly using conventional dyeing. In its production process often need to add a variety of additives to improve dyeing, lightfastness and flame resistance. Its scientific name polypropylene fiber, that is, the flame is nearly melting, flammable, slow to smoke and black smoke from the fire, the upper flame yellow, the bottom of the blue, exudes an oil flavor, ashes after burning hard yellowish brown particles, hand twist fragile.
