preparation example Construction

[0028] A kind of preparation method of formaldehyde-free color-fixing agent of the present invention, realize by following steps:

[0029] (1) Add acrylamide monomers with ammonium groups, acryloyloxyethyl succinate, unsaturated chlorosilane monomers, and deionized water to the reactor in sequence, start stirring, and start heating to raise the temperature;

[0030] (2) When the temperature in the reactor rises to 30°C to 50°C, add an initiator solution, which is prepared from the initiator and part of the deionized water;

[0031] (3) The reactor is then placed in a microwave reactor, and then subjected to microwave radiation, after which, the microwave reactor is closed and the temperature is lowered to discharge the material to obtain the color fixing agent.

Abstract

The invention relates to a formaldehyde-free fixing agent and a preparation method thereof. The preparation method comprises the following steps: (1) sequentially adding an acrylamide monomers havingammonium groups, acryloyloxy ethyl succinate, an unsaturated chlorosilane monomer and deionized water into a reactor, then starting to stir, and heating; (2) when the temperature in the reactor risesto 30-50 DEG C, adding an initiator solution, wherein the initiator solution is prepared from an initiator and part of the deionized water; (3) then, putting the reactor into a microwave reactor for performing microwave irradiation; after that, turning off the microwave reactor, cooling and discharging to obtain the fixing agent.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, in particular to a formaldehyde-free color fixing agent and a preparation method thereof. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for clothing performance and quality, and color fastness is one of the important indicators. Reactive dyes have a complete color spectrum and bright colors, which can endow textiles with bright colors and are deeply loved by consumers. However, when reactive dyes dye dark colors, the wet rubbing fastness is difficult to meet the requirements of high-quality products, and it is often necessary to improve the color fastness through color fixing treatment. After the color-fixing treatment of the color-fixing agent, the color fastness, soaping and perspiration fastness on the fabric can be improved, so as to meet the needs of printing and dyeing.
