Problems solved by technology

Although reactive dyes form a functional group covalent bond between the dye and the fiber, the stability of this bond is not high, and the deionized hydrolysis of the dye or insufficient soaping of the unbonded dye during dyeing will also make it Decreased color fastness, difficult to meet current printing and dyeing requirements

[0027] A kind of preparation method of fabric color fixing agent of the present invention, realize by following steps:

[0028] (1) Add the organic quaternary ammonium compound, cardanol glycidyl ether, and deionized water with halohydrin groups into the reaction kettle successively, start stirring, and start to heat up;

[0029] (2) Pour the unsaturated amide monomer and deionized water into the first high-level tank and stir to make it evenly mixed. Put the initiator and deionized water into the second high-level tank and stir to fully dissolve it. When the reaction When the temperature in the kettle rises to 85°C to 120°C, carry out nitrogen protection, then open the two high-level tanks, and drop the solutions of the two high-level tanks into the reaction kettle at a constant speed, and the dropping time is 3 to 6 hours;

[0030] (3) Then add epichlorohydrin dropwise to the reaction kettle, the dropping time is controlled within 1 to 3 hours, the temperature is maintained ...

Abstract

The invention relates to a fabric color fixing agent and a preparation method thereof. The method comprises the following steps: (1) sequentially adding an organic quaternary ammonium compound havinga halohydrin group, cardanol glycidyl ether and deionized water into a reaction kettle, starting stirring, and starting to heat up; (2) adding an unsaturated amide monomer and the deionized water intoa first high-level tank and stirring until the mixture is uniformly mixed, and adding an initiator and the deionized water into a second high-level tank and stirring until the mixture is fully dissolved; when the temperature in the reaction kettle rises to 85-120 DEG C, performing nitrogen protection, then opening two high-level tanks, and dropwise adding the solution of the two high-level tanksinto the reaction kettle at a constant rate, wherein the dropwise addition time is 3-6 hours; (3) then, dropwise adding epoxy chloropropane into the reaction kettle, controlling the dropwise additiontime to be 1-3 hours, maintaining the temperature to be 100-135 DEG C, then carrying out a reaction for 1-3 hours under the condition of heat preservation, and cooling and discharging after the heat preservation process is finished so as to obtain the color fixing agent.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, in particular to a fabric color fixing agent and a preparation method thereof. Background technique [0002] Reactive dyes are the most popular dyes for cellulose fibers in the market due to their complete color, variety and chromatogram, low cost and convenient use. They are widely used in the dyeing weight of cotton fabrics. Although reactive dyes form a functional group covalent bond between the dye and the fiber, the stability of this bond is not high, and the deionized hydrolysis of the dye or insufficient soaping of the unbonded dye during dyeing will also make it The color fastness is reduced and it is difficult to meet the current printing and dyeing requirements. Dyeing color fixing agent is an auxiliary agent to improve the soaping and perspiration fastness of dyes on fabrics, and is widely used in the textile printing and dyeing industry.
