| titleOfInvention | Reactive dye and preparation method thereof |
| abstract | The invention discloses a reactive dye and a preparation method thereof. In order to achieve the above purpose, the reactive dye is prepared from a reactive dye and hydroxy amide carboxylate in a molar ratio N of 0.1: 1 to 2: 1, wherein the hydroxy amide carboxylate is prepared by neutralizing the pH value of a reaction product of hydramine and dicarboxylic anhydride in an equal molar ratio in a solvent to 8-10 by an alkaline solution. The method for preparing the reactive dye comprises the following steps: (1) taking the hydramine and the dicarboxylic anhydride in equal molar ratio to carry out amidation, neutralizing by using the alkaline solution until pH value is 8-10, and removing the solvent to obtain the hydroxy amide carboxylate; (2) reacting the hydroxy amide carboxylate with the reactive dye, and drying and grinding the product to obtain the reactive dye. The reactive dye and the preparation method of the reactive dye can be used for solving the problem that the existing reactive dye is hard to be applied in the leather dye; meanwhile, the color fastness of the leather is improved; the concentration of the residual dye of the dye waste solution is improved. |
