Active composite dye

Abstract

The active composite dye includes at least one of compound A, at least one of compound B and at least one of compound C, with the compounds A, B and C being shown. The active composite dye is suitable for dyeing cellulose or protein fiber, and has the composition meeting the environmental and ecological requirement of Oeko-Tex Standard 100. The active composite dye has high build-up, good level dyeing property, good color reproduction, high dye uptake and other excellent performance.

Description

technical field [0001] The invention relates to a reactive composite dye, in particular to a reactive composite dye suitable for dyeing cellulose or protein fibers. Background technique [0002] In the dyeing of cellulose fibers, it is easy to produce color flower and cylinder difference by dyeing brown and black with the combination of ordinary red, yellow and blue reactive dyes. Now most of them use reactive red, yellow and blue dyed coffee colors containing chloro-s-triazine and vinyl sulfone diactivating radicals. There are certain differences in alkali sensitivity, influence on bath ratio and sensitivity to temperature, so the color reproducibility of dyeing is poor, and it is easy to cause color flower. Contents of the invention [0003] The invention provides a reactive composite dye, which has excellent dyeing synchrony and level dyeing property among the compositions, and has high color fixing rate. [0004] A reactive composite dye, comprising 5.0 to 60.6% of t...

Problems solved by technology

Now most of them use reactive red, yellow, and blue dyed coffee color containing chloro-s-triazine and vinyl sulfone diactivating group, because of their affinity to fibers, coloring rate, color fixing rate, salt, and color. There are certain differences in the sensitivity of alkali, the influence on bath ratio and the sensitivity to temperature, so the color reproducibility of dyeing is poor, and it is easy to cause color flower
