Fabric color fixing agent for clothing and preparation method thereof

Abstract

The invention provides a fabric color fixing agent. The fixing agent is prepared from, by weight, 20-25 parts of acrylic ester, 1-4 parts of azodiisobutyronitrile, 8-10 parts of chitosan quaternary ammonium salt, 5-8 parts of octadecyl dimethyl amine, 3-5 parts of acetic acid, 6-8 parts of diethylenetriamine, 4-6 parts of dicyandiamide, 1-3 parts of organic siloxane and 50-80 parts of water. The invention further provides a preparation method of the fixing agent. The preparation method comprises the following steps that a formula amount of acrylic ester is mixed with the azodiisobutyronitrile, heating is performed to reach 45-60 DEG C, reaction is performed during stirring for 2-4 hours, the residual components are added according to the formula amounts after cooling is performed to reach room temperature, reaction is performed during stirring for 1-1.5 hours to obtain the fixing agent. The fixing agent is non-toxic, formaldehyde-free, green and environmentally friendly, has no harm to human and strong color fastness, is antibacterial, anti-wrinkle and antistatic, a preparation process is simple, reaction conditions are mild, and the raw materials are easy to obtain.

Description

technical field [0001] The invention specifically relates to a fabric color fixing agent for clothing and a preparation method thereof. Background technique [0002] In the weaving process of clothing fabrics, although some dyes can be dyed with brighter colors, due to the poor fastness to wet treatment, the phenomenon of fading and color sticking is more serious, which not only makes the appearance of the fabric itself old, but also dyes from the existing ones. The dyed wet fibers fall off and stain white or dyed fibers of other colors; clothes of different colors will also stain each other and match colors during washing. Therefore, in the dyeing process, it is necessary to add a color-fixing agent to enhance the fastness of the dye. Dye fixing agent refers to a class of compounds that can fix dyes and fibers more effectively, and it can improve and increase the fastness of dyed fabrics. Traditional color-fixing agents contain substances harmful to human health such as f...
