Silica sol containing dyeing agent for wig composite fiber and preparation method thereof

Abstract

The invention discloses a silica sol containing dyeing agent for wig composite fiber. According to the dyeing agent, a reactive dye is employed to prepare a dyeing solution, cationic etherified starch is employed to conduct cationization treatment on polyvinyl alcohol, cationized polyvinyl alcohol reacts with the reactive dye to obtain a reactive dyeing solution, which has high adhesion and dying uniformity, and certain retarding and protecting effects, and can improve the dyeing effect of composite fiber. The added silica sol has good permeability, and can reach the efficacy of color fixing, toughening, spinnability improvement and the like after combing with composite fiber. The wig fiber treated by the dyeing agent provided by the invention has firm and uniform color, is heat resistant and stain resistant, is tough and durable, and is difficult to generate static electricity.

Description

technical field [0001] The invention relates to the technical field of wig dyeing agents, in particular to a silicon sol-containing dyeing agent for wig composite fibers 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 reach expected effect, ...

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
