Polypropylene fibers are widely used in engineering products processing
Polypropylene fiber works on the molecular structure does not contain a dye capable of binding to a chemical group, it is more difficult to dye. Usually melt coloring, pigment preparations and polypropylene polymer uniformly mixed in a screw extruder, melt-spun through colored fiber obtained high color fastness. Another method is acrylic acid, acrylonitrile, vinylpyridine copolymerization or graft copolymerization, the polymer with the dye molecules introduced on the combination of a polar group, and then dyeing by conventional methods directly. In polypropylene production process often necessary to add various additives to improve dyeability, light resistance and flame retardancy.
Petroleum refining byproduct of propylene as raw materials obtained isotactic polypropylene synthetic fiber works of Chinese trade name. Also known as polypropylene fiber works. Rich source of raw materials, production process is simple, relatively inexpensive product than other synthetic fibers. Physical and mechanical properties of fibers are characterized by: high strength (short fibers of 4 to 6 g / denier filaments of 5 to 8 g / d), wet and dry strength basically the same, the proportion of small (0.91), abrasion resistance, corrosion. World annual production of polypropylene fiber works in 1980, has more than 1 million tons.
There are varieties of fiber filaments (including non-textured filament and bulked textured filament), staple fibers, bristles, split film fibers, hollow fibers, shaped fibers, various composite fibers and nonwoven fabric and the like. The main purpose is to produce carpeting (including carpet backing and suede), fabrics, furniture fabrics, all kinds of rope, tape, nets, absorption felt, reinforced construction materials, packaging materials and industrial fabrics, such as fabric, cloth bags Wait. Further applications are becoming increasingly widespread in terms of clothing, with a variety of fiber blends made from different types of blended fabrics, knitted after processing can be made into shirts, outerwear, sportswear, socks and so on. Xu made of polypropylene hollow fibers are, light, warmth, and good elasticity.
