Abstract

The invention provides a textile dye fixing agent and application thereof, and belongs to the technical field of textile printing and dyeing assistants. Specifically, the textile dye fixing agent comprises a mole of at least one copolymerized unit shown as formula (I), b mole of at least one copolymerized unit shown as formula (II) and c mole of at least one copolymerized unit shown as formula (III); the beneficial effects are that: the textile dye fixing agent disclosed by the invention is a polymer; the preparation method is simple, the reaction is mild, the phenomena of implosion, gelling and the like are avoided, a new branched structure containing silicon-carbon chains, nitrogen-carbon chains, particularly silicon-oxygen chains is introduced, and sulfydryl is introduced and condensedinto disulfide bonds, so that the crosslinking density of the textile dye fixing agent is further increased, and the resistances such as wear resistance, water soaking resistance and the like are greatly improved.

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...
