Abstract

The invention discloses a red reactive dye mixture. The dye mixture is formed by mixing of three different dyes according to a mass ratio of 70-80:10-15:10-15. The reactive dye has the advantages of excellent sunlight fastness, perspiration fastness and rubbing fastness, and compared with all components in the composition, the performance of the mixture is higher than that of any single color variety or mixture of other ratio.

Description

technical field [0001] The invention relates to a red reactive dye mixture and its preparation and application, belonging to the field of dyes. Background technique [0002] Recently, printing and dyeing using reactive dyes has high requirements for dyeing quality and economic efficiency of dyeing methods, so reactive dyes are required to have good properties, and some new and readily available dye compositions with good properties have been developed. Textiles used outdoors, such as sportswear, and military and police training clothing, often need to have good light fastness, rubbing fastness and perspiration fastness, and the combined performance of the current reactive dyes often cannot meet the needs. [0003] At present, there is an urgent need to develop a group of dyes in the market, especially dyes with excellent fastness properties for printing and dyeing fabrics, which can be used for dyeing and printing of dyes containing hydroxyl or nitrogen-containing fibers, an...
