Polypropylene industrial silk is difficult to color in the production, let's take a look at how polypropylene industrial silk is colored.
Polypropylene in the macromolecular structure does not contain chemical groups that can be combined with dyes, so dyeing is more difficult.
1. Using melt coloring method, the pigment preparation and polypropylene polymer are evenly mixed in the screw extrusion press, and the colored fiber is obtained with high color fastness after melt spinning.
2. Copolymerization or graft copolymerization with acrylic acid, acrylonitrile, vinylpyridine, etc., so that polar groups that can be combined with dyes are introduced on polymer macromolecules, and then directly dyed by conventional methods.
In the process of polypropylene production, various additives are often needed to improve dyeing, light resistance and fire resistance.
At the same time, polypropylene industrial silk has the advantages of anti-aging, small thermal shrinkage, and impact resistance, etc., can be made into shirts, coats, sports clothes, socks, etc., but the existing polypropylene industrial silk is still not strong flame retardant, and the performance is not strong, so that the made of clothing there are flammable and easy to scratch and other shortcomings.
Xuzhou Peace Chemical Fiber Co., Ltd. is located in Xuzhou, Jiangsu. It has focused on the research and development and production of polypropylene, high strength, high strength, high strength, high strength, anti-aging, acid and alkali resistant, etc., which also make polypropylene high strength. Wire can be applied to all aspects of our lives. Peaceful chemical polypropylene, manufacturers supply, complete products, high quality after-sales service, users can rest assured to buy. Peace chemical fiber also has a polypropylene industrial silk, polypropylene high strength wire, high-strength polypropylene wire, polypropylene high strength, high-strength propylene, and hydrazine industrial wire.
