Problems solved by technology

In the prior art, the melt coloring method is usually used for polypropylene, and the pigment preparation and the polypropylene polymer are uniformly mixed in a screw extruder. Although the fiber obtained by this method has high color fastness, it is difficult to adapt to clothing fabrics. The rapid change of popular colors and the diversity of color requirements limit the variety of fabric varieties

Abstract

The invention relates to dyeable polypropylene modified fibers and belongs to the technical field of fiber preparation. The dyeable polypropylene modified fibers provided by the invention are preparedby spinning polypropylene blended resin; the polypropylene blended resin is prepared from the following components in percentage by weight: 93.0 to 98.0 percent of first isotactic polypropylene resin, 0.10 to 0.25 percent of second isotactic polypropylene resin, 0.3 to 1.5 percent of organic titanium compound, 0.5 to 5.0 percent of polyethylene compound and 0.3 to 2.5 percent of auxiliary agent.The dyeable polypropylene modified fibers provided by the invention have a hydrophilic property like nylon and have an excellent dyeing rate on disperse dyestuffs, and the extensibility and toughnessof the fibers are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of fiber preparation, more specifically, the invention relates to a dyeable polypropylene modified fiber. Background technique [0002] Polypropylene, also known as polypropylene fiber, is the Chinese trade name of synthetic fiber isotactic polypropylene fiber made from propylene. The varieties of polypropylene include filament, short fiber, hollow fiber, special-shaped fiber and composite fiber, etc., because of its low density, good hydrophobicity, corrosion resistance, high strength and low price, it has developed rapidly and has become the second largest Synthetic fiber varieties, and are widely used in industrial and civil fields, especially for carpets, decorative cloths, furniture cloths, ropes, strips, fishing nets, building reinforcement materials, filter cloths, bag cloths, etc.; The development of denier and ultra-fine polypropylene fiber is becoming more and more widely used in clothing. It can ...
