Abstract

The disperse red dye mixture with raised sublimation fastness consists of dye in the chemical general expression as shown in 5-95 wt%, and C.I. disperse red 343, C.I. disperse red 92 or C.I. disperse red 146 in 5-95 wt%. The disperse red dye mixture has sublimation fastness raised to Level 3, and may be compounded with disperse blue 2BLN and disperse yellow in the same sublimation fastness to form various kinds of marketable dyes with balanced sublimation fastness. It may be also used directly in dyeing.

Description

technical field [0001] The invention relates to a disperse dye suitable for dyeing polyester fibers or fabrics, in particular to a disperse red dye mixture with improved sublimation fastness. This disperse red dye can be used as one of the basic ternary colors. Disperse yellow 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 red 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 staini...
