Abstract

The invention relates to a performance-improved disperse blue dye mixture which is prepared by mixing a dye part and an assistant part. The performance-improved disperse blue dye mixture is characterized in that the dye part is at least prepared by mixing the following three dyes: a first dye which has a chemical structural general formula (I) and accounts for 40-80% of the total weight of the dye part; a second dye which has a chemical structural formula (II) and accounts for 10-30% of the total weight of the dye part; and a third dye which has a chemical structural formula (III) and accounts for 10-50% of the total weight of the dye part, wherein the chemical structural general formula (I), the chemical structural formula (II) and the chemical structural formula (III) are shown in the specification; and in the chemical structural general formula (I), n is an integer from 1 to 4, and R is a group NH or O.

Description

technical field [0001] The invention relates to a disperse blue dye mixture, in particular to a disperse blue dye mixture suitable for dyeing polyester fibers or fabrics. Background technique [0002] With the improvement of people's living standards, people have new requirements for the function and quality of textile and clothing. At present, the textile dyeing and finishing and clothing processing industries are speeding up to follow up with the international synchronization. However, in the actual production and processing process, they have found that Quite a few questions. One of them is that in the textile dyeing process, due to the incomplete performance of the existing dyes, the dyeing quality and grade cannot meet the requirements. Therefore, it is imperative to replace the existing dyes and improve their performance. [0003] After more than ten years of dyeing and finishing application practice, it has been proved that among the disperse blue and disperse violet...
