Embodiment Construction
[0007] The preparation of a composite color-blocking reactive black dye B-ED of the present invention is: according to the corresponding process, p-(vinylsulfone sulfate) aniline is dissolved, and diazotization is carried out after filtration, and then condensation, coupling, salting out , filtering and drying to prepare monomer No. 1 reactive orange dye and B-BF reactive navy blue dye respectively. Mix 100 grams of No. 1 reactive orange dye, 350 grams of B-BF reactive navy blue dye, 2 grams of butyl oleate, 50 grams of co-solvent and 1-2‰ of the total weight of detergent fatty alcohol polyoxyethylene ether and pulverize to the desired particle size.

A composite combined reactive black dye 4 is prepared from reactive orange dye No.1, reactive dark blue dye B-BF, dust-proofing agent and solubilizer in Wt ratio of (0.5-1.5):(3-5):(0.01-0.05):(0.3-0.6). Its advantages are high black level, high color fastness, gay color and no pollution.
Description
technical field [0001] The invention relates to a composite color matching reactive black dye mainly composed of color matching reactive dyes. Background technique [0002] At present, monomer reactive black dyes produced by dye manufacturers. This kind of dye has relatively low color fastness, poor lifting power and blackness, especially poor shade brightness, and it is dusty when used, so it is not easy to wash. Contents of the invention [0003] In order to improve the brilliance, color fastness and performance of the dye, the technical solution of the present invention is: a composite color matching reactive black dye is mainly composed of No. 1 reactive orange dye, B-BF reactive navy blue dye, dustproof agent and auxiliary Solvent compound. [0004] The weight of a kind of composite color matching reactive black dye of the present invention mainly consists of: No. 1 reactive orange dye: B-BF reactive navy blue dye: dustproof agent: cosolvent=0.5--1.5: 3-5: 0.01--0.0...
