Example Embodiment

[0010] The dyeing agent of this embodiment is made of the following raw materials in parts by weight: reactive dye 10, hydroxypropyl methylcellulose 1, fatty alcohol polyoxyethylene ether 0.2, polyvinyl alcohol 4, acetic acid / sodium acetate buffer solution appropriate amount, cationic Etherified starch 0.4, appropriate amount of sodium hydroxide, 150 deionized water.

[0011] The preparation method of the stain is:

[0012] (1) First add polyvinyl alcohol to 20 parts by weight of deionized water, heat to 80°C, stir until it is completely dissolved and then cool to 40°C, then add cationic etherified starch, and adjust the pH of the solution to 7 with sodium hydroxide , High-speed stirring and mixing reaction for 2h to obtain cationized polyvinyl alcohol etherified starch solution for use;

[0013] (2) Add the reactive dye to the remaining deionized water, heat the aqueous solution to 50°C, then add the remaining ingredients except the acetic acid / sodium acetate buffer solution, stir ...

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 ...
