Problems solved by technology

[0003] At present, there are many kinds of color fixing agents on the market, and the quality is uneven. The color fixing agent Y used earlier is not environmentally friendly and contains formaldehyde, which has been abandoned by people. Most of the color fixing agents used now are formaldehyde-free color fixing agents. Most of the color fixing agents on the market only solve the problem of color fastness to washing, especially for fabrics used in summer and home textile fabrics. Perspiration fastness is another important indicator for evaluating color fastness

Abstract

The invention discloses a cotton sweat-resistant formaldehyde-free color fixing agent. The cotton sweat-resistant formaldehyde-free color fixing agent is prepared from the following components in parts by weight: 50 to 100 parts of unsaturated quaternary ammonium salt olefin, 10 to 20 parts of functional monomer, 6 to 12 parts of water-soluble unsaturated polyoxy alkyl ether, 5 to 10 parts of crosslinking reaction monomer, 0.01 to 1 part of self-crosslinking accelerant, 0.005 to 0.02 part of metal ion chelating agent, 0.8 to 1.5 parts of initiator, and 20 to 50 parts of deionized water. The invention also discloses a preparation method and application of the cotton sweat-resistant formaldehyde-free color fixing agent.

Description

technical field [0001] The invention relates to the fields of textile and chemical printing and dyeing auxiliaries, in particular to a perspiration-resistant and formaldehyde-free color-fixing agent for cotton, a preparation method and application thereof. Background technique [0002] With the improvement of people's living standards, the quality requirements for textiles are also gradually increasing. Cotton fabric is more and more favored by people because of its advantages such as comfortable wearing and good hygroscopicity. After dyeing, cotton fabric generally needs to be finished to achieve better color fastness. Cotton fabrics are generally dyed with reactive dyes. Reactive dyes contain anionic water-soluble groups such as sulfonic acid groups and carboxyl groups. In addition to the van der Waals effect of dyes on fibers, dye molecules also need to overcome the charge repulsion between fibers and dyes, so that dyes are Fiber adsorption. However, this adsorption is ...
