Problems solved by technology

In the color fixing agent for cotton, according to the Oeko-Tex standard, the indicators of textile color fastness include soaping resistance, water washing resistance, friction resistance, perspiration resistance, sun resistance, and chlorine resistance. It is environmentally friendly and does not contain formaldehyde, which improves sensitive colors. Fastness, little impact on color light and other indicators, among them, chlorine resistance, significantly improving the color fastness of sensitive colors while achieving environmental protection and formaldehyde-free research progress is slow

Abstract

The invention discloses a synthetic method of a novel environment-friendly chlorine-resistant color fixing agent. Epoxy chloropropane, diethylenetriamine and diallylamine serve as the raw materials, and the novel environment-friendly chlorine-resistant color fixing agent is prepared through a reaction. Hydroxyl and imino groups exist in the color fixing agent and can be combined with dye, chloridion of the dye can be closed, and a thin polymer film can further be formed on the fiber surface.

Description

technical field [0001] The invention relates to a color-fixing agent for textiles, and more specifically, the invention relates to a synthesis method of a novel environmentally friendly chlorine-resistant color-fixing agent. Background technique [0002] The dyeing of cellulose fiber fabrics such as cotton usually uses direct dyes and acid dyes, which can make the dyed fabrics get bright colors, but the color fastness is poor, that is, the direct dyes and acid dyes on the surface of the dyed fabrics are easy to fall off during the washing process , Not only causes the dyed fabric to fade, but also stains other fabrics, which brings troubles to the consumption and finishing of textiles. In addition, during the use of dyed fabrics, human sweat and saliva, oxygen and ultraviolet light in the environment will break the covalent bonds between reactive dyes and cellulose fibers, resulting in poor fastness and fading of fabrics. In order to improve the stability of the dye on th...
