Description

technical field

[0001] The invention relates to a reactive dye, in particular to a composite reactive red dye, which is suitable for dyeing cotton, linen, viscose fiber and the like. Background technique

[0002] At present, the red dye commonly produced and used in the market—reactive red B-4BD is a kind of color-blocking dye compound. Its fastness, heat stability and alkali resistance are poor, and it is dusty when used, making it difficult to clean.

[0003] With the improvement of living standards, people's requirements for textile products are getting higher and higher, so that the requirements for the performance of reactive dyes used in textile dyeing are becoming increasingly stringent. Reactive dyes must not only have excellent color fastness and dyeing performance, but also meet environmental protection requirements. Contents of the invention

[0004] The invention provides a composite active red dye with high color fixing rate and high utilization rate, and is ...
