Embodiment 1

[0058] A formaldehyde-free color-fixing agent for full-color reactive dyes, which is prepared by compounding a first color-fixing agent and a second color-fixing agent at a weight ratio of 2:2.5.

[0059] Specifically, the compounding step can be to take a predetermined amount of the first color-fixing agent and add it to the reaction container, and then add a predetermined amount of the second color-fixing agent to the reaction container, and the temperature in the reaction container will rise after completion When the temperature reaches 40-50°C, start stirring to mix the first color-fixing agent and the second color-fixing agent evenly, and then compound them into the formaldehyde-free color-fixing agent for full-color reactive dyes.

[0060] The raw material components for the preparation of the first color fixing agent and the parts by weight of each component are: 12 parts of diallylamine, 15 parts of epichlorohydrin, 10 parts of N-vinylpyrrolidone, methacryloyl 65 parts...

Embodiment 2

[0073] A formaldehyde-free color-fixing agent for full-color reactive dyes, which is prepared by compounding a first color-fixing agent and a second color-fixing agent at a weight ratio of 1:2.

[0074] The specific compounding step can be to take a predetermined amount of the first color fixing agent and add it to the reaction container, and then add a predetermined amount of the second color fixing agent to the reaction container. After completion, the temperature in the reaction container Raise the temperature to 40-50°C, start stirring, and mix the first color-fixing agent and the second color-fixing agent evenly, and then compound them into the formaldehyde-free color-fixing agent for full-color reactive dyes.

[0075] Wherein the preparation raw material components of the first color fixing agent and the parts by weight of each component are: 15 parts of diallylamine, 18 parts of epichlorohydrin, 15 parts of N-vinylpyrrolidone, methacryloyl 70 parts of oxyethyltrimethyla...

Abstract

The invention provides a formaldehyde-free fixing agent for all-color-series reactive dyes as well as a preparation method and a use method of the formaldehyde-free fixing agent. The formaldehyde-free fixing agent is formed by compounding a first fixing agent and a second fixing agent in a ratio being (1-3):(2-4) in parts by weight. According to the formaldehyde-free fixing agent for all-color-series reactive dyes, two different types of fixing agents are compounded, so that the formaldehyde-free fixing agent contains quaternary ammonium salt cation groups and reactive groups, the groups can have a certain synergistic effect, and the fixing performance of the formaldehyde-free fixing agent is more outstanding.

Description

technical field [0001] The invention belongs to the field of dyeing and finishing auxiliaries for textile products, in particular to a formaldehyde-free color-fixing agent for full-color reactive dyes and a use method thereof. Background technique [0002] It is known that the so-called color fastness refers to the performance that the dyes on the fabric can maintain their original color to varying degrees under the action of various factors during the process of taking or processing. After the fabric is dyed, in addition to satisfactory color and luster, good color fastness is also required. Reactive dyes are popular in the printing and dyeing industry because of their bright color, complete chromatogram, economical process, good level dyeing, and low price. Among the pure cotton printing and dyeing products, the printing and dyeing process with reactive dyes as the main body has accounted for about 80% of the entire process, and reactive dye dyeing has become the mainstre...
