Abstract

This invention discloses disperse orange dye mixture with improved sublimation fastness, whose general chemical formula is shown in chemical formula (I). The sublimation fastness of the disperse orange dye mixture is improved to 3.5 grade. The disperse orange dye mixture, together with disperse blue 2BLN and disperse red with the same sublimation fastness, can constitute conventional commercialized dyes with various colors, which have balanced sublimation fastness. Compared with the traditional ternary dye mixture composed of disperse blue 2BLN, disperse yellow E-RG and disperse red 3B, the disperse orange dye mixture can avoid the serious chromatic light change problem caused by ununiform sublimation of different components during middle-depth dyeing of polyester fibers and fabrics. The disperse orange dye mixture can obviously improve chromatic light change before and after setting, and has a high qualification rate. The disperse orange dye mixture can also be used in direct dyeing. In chemical formula (I), RA is dimethyl sulphonylamino or nitro; RB and RC are halogen or H.

Description

technical field [0001] The invention relates to a sublimation fastness-improving disperse orange dye mixture suitable for polyester fiber or fabric dyeing. This disperse orange dye can be used as one of the basic medium-light matching colors. Disperse red and disperse blue with the same sublimation fastness constitute a group of medium-light matching color dyes for color matching. When polyester fibers and fabrics are dyed in medium depth , which solves the problem of serious color and light changes caused by inconsistent sublimation of each dye component. In addition, this disperse orange dye can also be used directly 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 us...
