The structure of varieties of polypropylene
Some artificial silk thread wholesale Xiaobian to introduce the variety structure of polypropylene
Varieties
Varieties of polypropylene with filament (including undeformed filament and texturized filament deformation), short fiber, bristles, membrane split fiber, hollow fiber, profile fiber, composite fiber and textile fabric etc.. Is mainly used for making carpets (including carpet backing cloth and suede), decorative cloth, fabric furniture, all kinds of rope, belt, fishing net, suction linoleum, building materials, packaging materials and industrial fabrics reinforced, such as cloth, cloth and so on. In addition to the application of clothing is also increasingly wide range, can be blended with a variety of fiber to make different types of blended fabric, knitted fabric, after the processing can be made into shirts, jackets, sportswear, socks, etc.. Made of polypropylene hollow fiber wadding is, light, warm, good elasticity.
Structure
Polypropylene does not contain chemical groups and dye binding in the molecular structure, it is difficult to stain. Is usually used melt coloring method, the pigment preparations and polypropylene polymer in screw extruder evenly mixed, after melt spinning get colored fiber color fastness is very high. Another method is and acrylic acid, acrylonitrile, vinyl pyridine copolymer or graft copolymerization, polymer molecules on the introduction and dye combined polar groups, and then directly with conventional method of staining. In the process of polypropylene production to improve the dyeing properties, light resistance and flame resistance with various additives often need.
