Abstract

The invention discloses a blue active dye mixture, which is characterized by comprising a mixture of dyes shown as general formulas (1), (2) and (3), wherein the weight part ratio of the dyes shown as the general formulas (1), (2) and (3) in the mixture is 80:(12-10):(10-8). The dye mixture can be applied to dyeing and printing hydroxyl-containing or nitrogen-containing fiber or a hydroxyl-containing or nitrogen-containing fiber material for ink jet printing, has high dye uptake, high leveling property, high lifting power, high water washing resistance, high light resistance and high comprehensive firm properties such as light ray resistance and dampness resistance.

Description

technical field [0001] The invention relates to a blue reactive dye mixture and its preparation and application, belonging to the field of dyes. Background technique [0002] Recently, the practice of using reactive dyes has put forward higher requirements for dyeing quality and economic efficiency of dyeing methods and environmental protection, so there is still a need for new types of dyes with good properties, high dye uptake, and especially good properties in their application. The resulting dye composition. Current dyeing requirements for reactive dyes, for example, should have sufficient substantivity, ease of washing, in addition to good color yield and high reactivity. In many cases, especially when dyeing in very dark shades, the combination properties of reactive dyes are often not satisfactory. [0003] Therefore, there is an urgent need to develop a group of dyes in the market, especially for dyes that need to be printed and dyed in very deep colors. For exampl...
