Embodiment Construction

[0007] The preparation of a composite color-blocking reactive black dye B-BGFF of the present invention is: according to the corresponding process, p-(vinylsulfone-based 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, 400 grams of B-BF reactive navy blue dye, and 1-1.5 grams of butyl oleate and grind them to the required particle size.

Abstract

A composite combined reactive black dye 1 is prepared from reactive orange dye No.1, reactive dark blue dye B-BF, and dust-proofing agent in Wt ratio of (0.5-1.5):(3-6):(0.01-0.05). Its advantages are high black level, gay color, high color fastness 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. The lifting power and blackness are poor, especially the color brightness is poor, and the dust is large 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 and dustproof agent. become. [0004] The weight of a 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 = 0.5--1.5: 3--6: 0.01--0.05. The composition can also be provided with 1-2% of the total wei...
