The invention relates to the disperse dye technology field, and provides an environmentally-friendly blue disperse dye mixture and applications in order to adapt the environmental protection trend and meet demands of textiles to disperse blue dyes with excellent performances. The dye mixture is prepared from a dye A and a dye B through mixing. The weight percentage of the dye A in the dye mixture is 60-95%, and the weight percentage of the dye B in the dye mixture is 5-40%. The blue disperse dye with a low cost, a high intensity and high fastness is provided, demands of high-end users home and abroad are met, and environmental protection requirements are met.
Description
technical field [0001] The invention relates to the technical field of disperse dyes, in particular to an environment-friendly blue disperse dye mixture. Background technique [0002] Disperse blue C.I.56 is currently recognized as the most important blue disperse dye, and dyeing with this dye can obtain particularly bright red light blue with high fastness. However, the disadvantage of this dye is that the dyeing strength is low. At the same time, because the dye is an anthraquinone dye, it is well known that the production of anthraquinone dyes has a large amount of wastewater, high chroma, and complex components. Because its aromatic structure is not easy to be destroyed, its biodegradability is poor, and the wastewater contains organic dyes, which have strong toxicity, large pH fluctuations, and large component changes. It is one of the difficulties in wastewater treatment. With the enhancement of environmental awareness, it is imminent to reduce the ecological damage c...
