Embodiment Construction

[0007] The preparation of a kind of composite reactive red dye B-2BF of the present invention is: dissolving p-(vinylsulfone-based sulfate) aniline, carrying out diazotization after filtration, then condensation, coupling, salting out, filtration and drying to obtain Monomer B-2BF reactive red dye. The monomer B-2BF active red dye, dustproof agent and co-solvent are mixed according to the following weight ratio: B-2BF60-94.%, butyl oleate 1-10% and 5-30%, and crushed to the required particle size.

Abstract

A composite reactive red dye 2 is prepared from the reactive red dye B-2BF (60-94 wt.%), dust-proofing agent (1-10) and solubilizer (5-30). Its advantages are gay color, high color fastness and no pollution.

Description

technical field [0001] The invention relates to a composite reactive red dye mainly composed of reactive red dye B-2BF. Background technique [0002] The B-2BF reactive red dyestuff produced by dyestuff manufacturers is a monomeric compound prepared from m-(vinylsulfone sulfate) aniline as the main raw material. This kind of color fastness is relatively low, the lifting power is poor, especially the color brightness is poor, the dust is large when used, and it is not easy to wash. Contents of the invention [0003] In order to improve the brilliance and color fastness of the dyestuff, the technical scheme solved by the present invention is: a kind of composite reactive red dye is mainly made of B-2BF reactive red dye prepared as main raw material with p-(vinylsulfone-based sulfate) aniline, Dustproof agent and co-solvent composite. [0004] The structural formula of B-2BF reactive red dye monomer is: [0005] The composite reactive red dye of the invention mainly cons...
