High-strength polypropylene fiber is the main material made of polypropylene, why use polypropylene for the high-strength polypropylene fiber, the main material? First of all, the chemical and physical properties of polypropylene itself is relatively stable, relatively light texture, good warmth. Today, Xiaobian with you to know about the specific knowledge of polypropylene it.

High-strength polypropylene fiber varieties of polypropylene
Polypropylene varieties are filaments (including undeformed filaments and expanded deformed filaments), staple fibers, bristles, film cleavage fibers, hollow fibers, profiled fibers, various composite fibers and nonwoven fabrics. The main purpose is the production of carpets (including carpet floor and suede), decorative cloth, furniture cloth, all kinds of ropes, strip, fishing nets, oil felt, building reinforcement materials, packaging materials and industrial fabrics, such as filter cloth, Wait. In addition, the application of clothing is also increasingly widespread, with a variety of fiber blended into different types of blended fabric, after knitting can be made after the shirt, coat, sportswear, socks and so on. Polypropylene hollow fiber made of floc, light, warm, good elasticity.

The Structure of Polypropylene of High Strength Polypropylene Silk
Polypropylene does not contain chemical groups that bind to dyes in macromolecules, so dyeing is difficult. Usually using the melt coloring method, the pigment formulations and polypropylene polymer in the screw extruder evenly mixed, after melt spinning to obtain colored fiber color fastness is high. Another method is with acrylic acid, acrylonitrile, vinyl pyridine copolymerization or graft copolymerization, the polymer macromolecules can be introduced with the dye on the combination of polar groups, and then directly by conventional methods of dyeing. In the production process of polypropylene often need to add a variety of additives to improve the dyeing, light resistance and flame resistance.
