Description

technical field

[0001] The invention relates to a disperse dye suitable for dyeing polyester fibers or fabrics, in particular to a disperse yellow dye mixture with improved sublimation fastness. This disperse yellow dye can be used as one of the basic ternary colors. Disperse red and disperse blue with the same sublimation fastness constitute a group of ternary color dyes for color matching. Solved the problem of serious shade change caused by inconsistent sublimation of each dye component. In addition, this disperse yellow dye can also be directly used for dyeing. Background technique

[0002] Disperse dyes are a kind of non-ionic dyes that are dyed in a dispersed state in the initial stage of the dyeing process. Among them, the sublimation fastness is one of the important indicators of the dyeing quality of disperse dyes. degree of sublimation. For sublimation fastness, the gray grading sample card is used to evaluate the degree of discoloration, fading and white cloth ...
