Abstract

The invention discloses a reactive red dye composition. The reactive red dye composition comprises a component A and a component B, wherein the component A is one or more which are selected from compounds represented by a formula (I), and the component B is one or more which are selected from compounds represented by a formula (II). When the reactive red dye composition is applied to dyeing or printing of cellulose fiber and other nitrogen-containing or hydroxyl-containing fiber materials, the characteristics of good solubility, wear resistance, excellent washing-resistant color fastness and the like are achieved.

Description

[0001] (1) Technical field [0002] The invention relates to a reactive red dye composition, in particular to a reactive red dye composition suitable for printing and dyeing of cellulose fibers or materials containing cellulose fibers, especially for printing. [0003] (2) Background technology [0004] Good reactive dyes generally have good solubility and diffusivity, because high solubility can improve the utilization rate of dyes, reduce the amount of dyes contained in wastewater after dyeing, and good diffusivity makes the reaction rate and fixation efficiency high, uniform The degree of dyeing and through-dyeing is good, so that the entire printing and dyeing time is reduced, and the cost of printing and dyeing is reduced. [0005] The development of new red reactive dyes requires not only high solubility and good diffusivity, but also good color fastness, compatibility and dyeing stability. At present, many commonly used red reactive dyes are difficult to have the above-...
