Problems solved by technology

However, the dye lacks affinity for cotton fibers, and because the quaternary ammonium salt in the molecule is combined with the dye parent through an amide bond, it is easily hydrolyzed, so that the dye loses its antibacterial properties

Embodiment 1

[0018] a. Dissolve 17g of 1-aminoanthraquinone and 20g of trifluoro-s-triazine in 200ml of nitrobenzene organic solvent, heat the mixture to 90°C, and raise the temperature to 120°C after 1 hour, at this temperature Continue to stir for about 1 hour, cool to 25-30°C, filter to obtain the dye intermediate 1-(4,6-dichloro-2-amino-s-triazine)aminoanthraquinone, wash with methanol, and dry in a vacuum dryer;

[0019] b. the dye intermediate 1-(4,6-dichloro-2-amino-s-triazine) aminoanthraquinone 10g prepared in step a is dissolved in 150ml DMF (N,N-dimethylformamide) organic solvent, heated to 55°C, slowly drop 5.5 g of 1-amino-3-dimethylaminobutane in 30 minutes, and then react for 2 hours. After the reaction is complete, evaporate the solvent DMF in a vacuum evaporator to obtain the dye intermediate 1- (4-chloro-6-(1-amino-3-dimethylaminobutane) 2-amino-s-triazine) aminoanthraquinone, dried in a vacuum dryer;

[0020] c. Dissolve 9 g of the dye intermediate prepared in step b in...

Embodiment 2-21

[0024] Example 2-21, the synthesis method of the antibacterial cationic reactive dye is basically the same as that of Example 1, and see Table 1 for other conditions.

Abstract

The present invention relates to one kind of antiseptic active cationic dye and its preparation process. The dye has matrix in anthraquinone structure, active group of sym-triazine monochloride or sym-triazine monofluoride, water soluble group of long carbon chain quaternary ammonium salt structure and the chemical structure as shown. The dye may be used in dyeing and antiseptic finishing of various kinds of fiber and has high antiseptic effect, high color fastness and lasting antiseptic performance. It is prepared through the following steps: dissolving anthraquinone A and sym-triazine trichloride or sym-triazine trifluoride in nitrobenzene solvent, heating, cooling and filtering to obtain intermediate B; dissolving the intermediate B in DMF solvent, adding tertiary amine, heating to react, evaporating DMF and vacuum drying to obtain intermediate D; dissolving the intermediate D in DMF solvent, adding alkyl halide, heating to react, washing with ethyl ether, re-crystallizing and drying.

Description

technical field [0001] The invention belongs to the fields of dye synthesis, textile dyeing and finishing, and in particular relates to an antibacterial cationic reactive dye and a preparation method thereof. Background technique [0002] Textile dyeing and finishing are two important wet processing processes, while traditional textile dyeing and finishing are carried out separately, which has the disadvantages of high cost, high energy consumption and large amount of sewage discharge. The dyeing and finishing technology that combines dyeing and functional finishing in one bath is of great significance for reducing production costs, saving energy, reducing waste water discharge, and protecting the ecological environment. Therefore, many experts at home and abroad have carried out a lot of research in this field, and have achieved certain results in the research of dyeing, antistatic, flame retardant, anti-ultraviolet, shrink-proof and anti-wrinkle finishing in one bath. How...
