Problems solved by technology

The conventional mercerizing process of cotton knitted fabrics is carried out before dyeing, but in the subsequent dyeing and finishing process, the mercerizing effect of cotton fabrics is significantly affected by long-term repeated physical friction, extrusion and chemical action. The superior performance of knitted fabrics improves product quality, and the processing route of cotton knitted fabrics that is dyed first and then mercerized has emerged as the times require. Alkali (NaOH200~280g / L) treatment, further hydrolysis of reactive dyes will cause floating color, therefore, the color fastness will be seriously reduced, and it needs to be fixed with a color-fixing agent with excellent tolerance, especially alkali resistance, to ensure the quality of the fabric promotion

Abstract

The invention provides a textile dye fixing agent and its application, belonging to the technical field of textile printing and dyeing auxiliaries, which specifically comprises a mole of at least one copolymerization unit shown in formula (I), b mole of at least one copolymerization unit shown in formula ( The copolymerization unit shown in II) and the polymer of c moles of at least one copolymerization unit shown in formula (III): the beneficial effect is: the textile dye fixing agent of the present invention is a kind of polymer, and its preparation method is simple , The reaction is mild, avoiding the phenomena of implosion and gelation, introducing a new branched structure with silicon-carbon chains, nitrogen-carbon chains, especially silicon-oxygen chains, and introducing mercapto groups and condensing them into disulfide bonds, making the color fixing agent The cross-linking density is further increased, which greatly improves the resistance to abrasion and blistering.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing auxiliaries, and in particular relates to a textile dye fixing agent and its application. Background technique [0002] Cotton fabrics are widely loved by consumers because of their moisture absorption and breathability. After continuous development, the quality of cotton fabrics is increasingly catering to people's increasing wearing needs. Among them, mercerized cotton fabrics are one of the most popular products among consumers. Mercerized cotton fabric is not only comfortable to wear and has a silky luster, but also has stable dimensions, crispness, and good wrinkle resistance. It is widely used in products such as T-shirts, moisture-wicking fabrics, and high-end shirts. The conventional mercerizing process of cotton knitted fabrics is carried out before dyeing, but in the subsequent dyeing and finishing process, the mercerizing effect of cotton fabrics is significantly aff...
