How is polypropylene industrial silk colored in production

Polypropylene is difficult to stain because it does not contain chemical groups that can bind with dyes in the macromolecular structure.

1. Using melt coloring method, pigment preparation and polypropylene polymer are evenly mixed in screw extruder. After melt spinning, colored fibers are obtained with high color fastness.

2. Copolymerization or graft copolymerization with acrylic acid, acrylonitrile, vinylpyridine, so that the polymer macromolecules can be introduced with the polar groups combined with dyes, and then directly dyed by conventional methods.

In the process of polypropylene fiber production, various additives are often added to improve the dyeability, light resistance and fire resistance.

At the same time, polypropylene industrial silk has the advantages of anti-aging, small thermal shrinkage, and impact resistance. It can be made into shirts, coats, sports clothes, socks and so on after processing of polypropylene industrial silk, but the existing polypropylene industrial silk still has flame retardant is not strong, and the performance is not strong and other shortcomings, so that the clothes made of flammable and easy to scratch.

Xuzhou Heping 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 silkpolypropylene high strength wirehigh-strength polypropylene wirepolypropylene high strengthhigh-strength propylene, and hydrazine industrial wire.
