Problems solved by technology

However, the existing red reactive dye composition is difficult to have comprehensive properties such as strong color fixation rate, good rubbing resistance, washing resistance and perspiration color fastness, and is extremely short of red reactive dyes with excellent comprehensive properties. Therefore, it is urgent to develop a A red reactive dye variety with better performance that can meet the above-mentioned characteristic requirements at the same time

Abstract

A red active dye composition and a preparation method and use thereof are provided. The red active dye composition comprises component B shown in formula (II), optional component A shown in formula (I), optional component C shown in formula (III) and an optional aid. The red active dye composition is suitable for dyeing various fiber materials, is high in color fixing rate and good in color fastness and has excellent comprehensive performances.

Description

technical field [0001] The invention relates to the field of reactive dyes, in particular to a red reactive dye composition and its preparation method and application. Background technique [0002] With the improvement of living standards, people's requirements for textile products are getting higher and higher, so the dyeing performance and dyeing process requirements of reactive dyes are becoming more and more stringent in the dye market, which promotes the development of reactive dyes to improve application performance . As a color species with a large market share, reactive red dyes are required to have good washing fastness, light fastness and dyeing reproducibility, high lifting power and color fixation rate. In order to improve the dyeing performance of dyes and make them have good dyeing effects, many red reactive dye patents have appeared in the industry, such as the open patent CN1807518A. However, the existing red reactive dye composition is difficult to have co...
