[Coloring method of polypropylene industrial silk]
Release date:[2022/5/13] Is reading[51]次

Polypropylene industrial silk is a kind of fiber raw material with anti-aging, low thermal shrinkage, high strength, high tensile strength and impact resistance, and is widely used in industrial production.

How polypropylene industrial silk is colored in production, follow the editor to see down.

Polypropylene does not contain chemical groups that can be combined with dyes in its macromolecular structure, so it is difficult to dye.

1. Using the melt coloring method, the pigment preparation and polypropylene polymer are uniformly mixed in a screw extruder, and the color fastness of the colored fibers is obtained by 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 into the polymer macromolecules, and then directly dyed by conventional methods.

In the process of polypropylene production, it is often necessary to add various additives to improve dyeability, light resistance and flame resistance.

At the same time, polypropylene industrial silk has the advantages of anti-aging, low thermal shrinkage, and impact resistance. After processing polypropylene industrial yarn, it can be made into shirts, outerwear, sportswear, socks, etc., but the existingpolypropylene industrial silk still exists. The shortcomings of weak flame retardancy and weak modification performance make the clothing made of it flammable and easy to be scratched.

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.
