Problems solved by technology

[0002] In the process of fabric weaving, although some dyes are brighter in color, due to the poor fastness of wet treatment, the phenomenon of fading and sticking is more serious, which not only makes the fabric itself look old, but also easily fades when it meets water. Easy to cause staining with other fabrics

Abstract

The invention relates to a fabric formaldehyde-free color-fixing agent and a preparation method thereof, belonging to the technical field of textile auxiliaries. The color fixing agent includes the following components in parts by weight: 15-25 parts of n-butyl acrylate, 5-9 parts of chitosan quaternary ammonium salt, 6-10 parts of isobornyl methacrylate, acryloyl oxide 7~14 parts of ethyltrimethylammonium chloride, 8~10 parts of triallylamine, 2~5 parts of organosiloxane, 3~5 parts of glacial acetic acid, 0.1~1 part of azobisisobutylcyanide, 100~120 parts of deionized water. The preparation process of the present invention is simple, and the prepared color-fixing agent does not contain formaldehyde and APEO, and can form an insoluble color lake on the surface of the fabric through the electrostatic combination of the cationic group in the color-fixing agent molecule and the anionic group in the dye. Block the water solvent group of the dye, thereby improving the washing fastness of the dyed fabric.

Description

technical field [0001] The invention belongs to the technical field of textile auxiliaries, and in particular relates to an formaldehyde-free color-fixing agent for fabrics and a preparation method thereof. Background technique [0002] In the process of fabric weaving, although some dyes are brighter in color, due to the poor fastness of wet treatment, the phenomenon of fading and sticking is more serious, which not only makes the fabric itself look old, but also easily fades when it meets water. It is easy to cause mutual staining with other fabrics. [0003] Fixing agent is an auxiliary agent used to improve the color fastness of dyes on fabrics to wet treatment. It can form insoluble colored matter with dyes on fabrics to improve the color fastness to washing and perspiration, and sometimes to improve its light fastness. Traditional color fixing agents contain harmful substances such as formaldehyde, but with the improvement of economic level, people have higher and hi...
