Abstract

An environmental protection type composite disperse gray dye with high dye uptake, fastness, reproducibility and sublimation fastness contains proportionally dye monomers A, B and C and assistant.

Description

technical field [0001] The invention relates to a composite dye, in particular to a composite environment-friendly disperse gray dye, which is suitable for printing and dyeing of polyester materials. Background technique [0002] In the printing and dyeing of polyester materials, disperse gray N products composed of disperse blue 2BLN, disperse red 3B, and disperse yellow RGFL are widely used, but because the polyester products printed and dyed with it will crack under certain conditions and produce Carcinogens or aromatic amines that are harmful to the human body do not meet the ecological and environmental protection requirements of Oeko-Tex Standard 100 promulgated by EU countries, so they cannot meet the export needs of textiles. In ordinary disperse gray N, two components belong to anthraquinone dyes, and the pollution of three wastes in production is relatively large. In addition, the reproducibility and sublimation fastness of dispersed gray N are not good, and the l...
