Problems solved by technology

However, in the printing and dyeing process, the utilization rate is relatively low, and the wet rubbing fastness of the dyed fabric, especially the wet rubbing fastness of the medium and dark fabrics is low, so the fabric needs to be fixed with a color-fixing agent after the dyeing process. treated to improve its color fastness

Abstract

The invention provides a textile printing and dyeing fixer and a preparation method thereof. The preparation method comprises the following steps: (1) putting a cationic monomer, 1,3-diallylamino-2-hydroxypropane, a (methyl)acrylate monomer containing an isocyanate group and water into a polymerization reaction vessel, uniformly stirring, heating and warming; (2) in a condition without oxygen anda condition of stirring, dropwise adding initiator solution to the polymerization reaction vessel, performing a polymerization reaction, wherein a temperature of the polymerization reaction is 80-100DEG C, and a mass concentration of the initiator solution is 1-10%, so the initiator solution is prepared by an initiator and a part of the water, and completely dropwise adding the initiator solutionwithin 1-3 hours; and (3) after completely dropwise adding, in the temperature of the polymerization reaction, continuously performing the polymerization reaction for 1-3 hours, cooling to room temperature, and discharging, to obtain the fixer.

Description

technical field [0001] The invention belongs to the technical field of textile auxiliaries, in particular to a textile printing and dyeing color fixing agent and a preparation method thereof. Background technique [0002] Cotton fabric fiber has become one of the most popular fabric fibers due to its superior wearing performance and environmental protection. It is widely used because of its good hygroscopicity, warmth retention, comfort and soft feel, as well as the characteristics of cleaning, health care, degradable recycling and so on. At present, the dyes used in cotton fiber printing and dyeing include vat dyes, sulfur dyes, direct dyes and reactive dyes. [0003] Reactive dyes, as the focus of development and use in cotton fabric dyes, have many advantages such as complete color spectrum, bright color, low price and convenient use. However, in the printing and dyeing process, the utilization rate is relatively low, and the wet rubbing fastness of the dyed fabric, esp...
