| titleOfInvention | Salt-free dyeing method for active dye |
| abstract | The invention relates to a salt-free dyeing method for an active dye, belonging to the field of printing and dyeing of active dyes. The salt-free dyeing method for the active dye comprises a modification treatment step and a dyeing step, wherein the modification treatment step comprises the following sub-steps of: (1) alkalinizing cotton fibers; (2) impregnating the alkalinized cotton fibers obtained by the sub-step (1) in an active intermediate solution for cotton fiber modification; and (3) impregnating the modified alkalinized cotton fibers obtained by the sub-step (2) in a carboxylic acid group-containing cationic reagent solution for cotton fiber cationic modification. By the alkalinization of the cotton fibers and the introduction of a plurality of carboxyl groups and amino groups, the reactivity of the cotton fibers is improved, and further cationization and reaction with the active dye are facilitated. |
