Polypropylene twisted yarn and more for the import of foreign embroidery, made from 6 shares. Line itself shiny, the color is also very elegant, each color contains gray ingredients, such as gray green, gray powder, gray blue and so on. The most suitable line to do yarn painting, embroidery painting and so on.
Polypropylene twine in the polypropylene varieties
Polypropylene varieties are filament (including undeformed filament and expanded deformable filament), short fibers, bristles, split membrane, hollow fiber, shaped fiber, all kinds of composite fibers and non-woven fabrics. The main purpose is the production of carpet (including carpet and suede), decorative cloth, furniture cloth, all kinds of ropes, tapes, fishing nets, linoleum, building reinforcements, 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 blends made of different types of blended fabrics, after knitting can be made into shirts, outerwear, sportswear, socks and so on. Made of polypropylene fiber hollow fiber, light, warm, good elasticity.
structure
Polypropylene in the macromolecular 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 the polypropylene production process often need to add a variety of additives to improve dyeing, light and fire resistance.
