The invention discloses a preparation method of a red dye. The red dye is prepared by mixing 50-90 wt% of a component A and 10-50 wt% of a component B, wherein the component A is composed of one or more of dye monomer A compounds disclosed as Formula (1), and the component B is composed of one or more of dye monomer B compounds disclosed as Formula (2). The prepared red dye has the advantages of higher depth, excellent color fastness, high level-dyeing property and high washability.
Description
technical field [0001] The invention relates to a preparation method of red dye. Background technique [0002] 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. [0003] At present, the red variety of dye monomer A on the market belongs to one of the three primary colors. It can be barely used in normal medium and dark colors, but the product has no advantage in making some extra dark colors, and the dyeing depth is not enough, while dye monomer B is mainly normal. Used in black, the depth is excellent, but the color fastness level is lacking. Contents of the invention [0004] In order to overcome the defects of poor dyeing fastness and dyeing performan...
