Abstract

A gray reactive dye mixture is characterized in that: the dye mixture is prepared by mixing dyes represented by formula (1), formula (2) and formula (3) according to the weight part ratio of 70-80:15-10:15-10, wherein A represents -SO2CH2CH2OSO3H or a group shown in the description, E represents -HNCH2CH2OCH2CH2SO2CH2CH2Cl or a group shown in the description, X, X1 and X2 each represent F or Cl, and D represents a group shown in the description or -HNCH2CH2OCH2CH2SO2CH2CH2Cl. Fabrics dyed or stamped by the dye mixture all have excellent performance of solarization resistance, sweat stain resistance and friction resistance.

Description

technical field [0001] The invention relates to a gray reactive dye mixture and its preparation and application, belonging to the field of dyes. Background technique [0002] Recently, the practice with reactive dyes has placed higher demands on the dyeing quality and the economical efficiency of the dyeing process, thus requiring new readily available dye compositions having good properties, especially with regard to their application. Textiles used outdoors, such as sportswear, and army and police training clothing, need to have good light fastness, rubbing fastness and perspiration fastness, and the combined performance of current reactive dyes often cannot meet the needs. [0003] Therefore, there is an urgent need to develop a group of dyes in the market, especially for dyes that require excellent fastness properties for printed and dyed fabrics. For example, it can be used for dyeing and printing of dyes containing hydroxyl or nitrogen-containing fibers, and can also b...
