The invention has the design characteristics and beneficial effects that: the invention selects a group of low-temperature and medium-temperature dyes to be matched with each other through the optimized combination of the dyes, and the medium-temperature dyes are mainly used as the dosage and the low-temperature dyes are used as the auxiliary dosage. The reason is that the invention selects the medium-temperature type dye with outstanding alkali resistance, but in order to ensure that the color light meets the gray requirement and ensure that the washing fastness and the sublimation fastness of the dye mixture are good, the invention selects a part of low-temperature type dye to adjust the level-dyeing property of the dye mixture.
In a word, the disperse grey dye mixture has good alkali resistance, so that a pretreatment desizing section and a dyeing section can be combined, a new process of a desizing and dyeing one-bath one-step method is realized, and good effects of energy conservation and emission reduction are achieved; meanwhile, the disperse gray dye mixture has good washing fastness and sublimation fastness, is low in price and high in quality, and guides a user enterprise to optimize the application idea of the dye.
