Abstract

The invention discloses a formaldehyde-free fixing agent, which comprises the following components in parts by weight: 80 to 120 parts of cationic monomer, 5 to 20 parts of unsaturated high-grade organic amine monomer, 3 to 10 parts of dicyandiamide, 4 to 18 parts of pH regulator, 0.001 to 0.05 part of metal ion chelating agent, 0.5 to 1 part of initiator, 2 to 10 parts of epichlorohydrin and 20 to 50 parts of deionized water. The formaldehyde-free fixing agent provided by the invention does not contain formaldehyde and alkylphenol ethoxylates (APEO); and meanwhile, the film-forming property of the fixing agent is utilized, a meshed film layer can be formed on the surface of the fiber, so that the dye dissolution is reduced, the color fastness of reactive dye dyed fabrics is improved, a fixing effect is good, the formaldehyde-free fixing agent can be applied to fixing colors of the reactive dye dyed fabrics, and the washable color fastness and boiling water soaking fastness of the fabrics are improved.

Description

Technical field [0001] The invention relates to a printing and dyeing auxiliary, in particular to an aldehyde-free fixing agent for dyeing cotton fabrics with direct dyes and reactive dyes and a preparation method thereof. [0002] Background technique [0003] In recent years, with the improvement of people's living standards, the demand for textiles has increased, and the requirements for textiles have become higher and higher, such as the requirements for bright colors and good color fastness of textiles. [0004] As a representative of the modern dye industry, reactive dyes are favored by the printing and dyeing industry because of their bright color, complete chromatogram, economical process, simple operation, good levelling performance, and low price. However, reactive dyes have their own shortcomings that are difficult to overcome. When they are dyed deep and dense, their color fastness is relatively poor. It is an important measure to improve the color fastness by finishing ...
