Hydroxypropyl methyl cellulose-containing dyeing agent for wig composite fiber and preparation method for dyeing agent

Abstract

The invention discloses a hydroxypropyl methyl cellulose-containing dyeing agent for a wig composite fiber. According to the dyeing agent, a dyeing solution is prepared from a reactive dye, cationic etherified starch is used for cationization treatment on polyvinyl alcohol, a reactive dyeing solution prepared by reacting the cationized polyvinyl alcohol and the reactive dye is high in adhesion and dyeing uniformity, and has certain retarding and protection effects, and a dyeing effect of the composite fiber can be improved; added hydroxypropyl methyl cellulose has the effects of adhesion improvement, water retention, film forming and the like, the bonding firmness of dye molecules and the fiber is improved, proteins mixed in the composite fiber can also be effectively protected, and deterioration of the fiber caused by enzymolysis of the proteins can be prevented; the wig composite fiber treated by the prepared dyeing agent is uniform and fast in dyeing, tough, durable and easy to clean and model.

Description

technical field [0001] The invention relates to the technical field of dyeing agents for wigs, in particular to a dyeing agent for wig composite fibers containing hydroxypropyl methylcellulose and a preparation method thereof. Background technique [0002] Wigs are very common in daily life, and the materials of wigs are also various. Among them, artificial composite fibers are widely used. One type is obtained by mixing and spinning protein, polyacrylonitrile, polyvinyl chloride and other materials. It has The texture and feel comparable to real hair, strength, toughness and flame retardancy are also better, and the market response is better. Because consumers have different demands on the color of wigs, the dyeing of wigs is an important link in the production process. Conventional dyeing agents are prone to swelling, denaturation, and uneven dyeing when processing the above-mentioned composite fibers, resulting in composite fibers. Lose due strength and toughness, can't ...

Problems solved by technology

Because consumers have different demands on the color of wigs, the dyeing of wigs is an important link in the production process. Conventional dyeing agents are prone to swelling, denaturation, and uneven dyeing when processing the above-mentioned composite fibers, resulting in composite fibers. Lose the proper strength and toughness, fail to achieve the expected effect, and the safety of the dye itself is also problematic
