Abstract

The present invention provides a composite reactive black dye mixture. The mixture is characterized in that the composite reactive black dye comprises at least dye compounds represented by a formula (1), a formula (2) and a formula (3) shown in the description, wherein M1, M2 and M3 are independent with one another and are H, Na and K; and D1, D2, D3, D4, D5 and D6 are independent with one anotherand are a fiber active group. The prepared composite reactive black dye mixture provided by the present invention has the characteristics of high reactivity, a high color-fixing rate, high solubilityand high lifting force, and is suitable for dyeing and printing of fiber materials.

Description

technical field [0001] The invention relates to a composite reactive dye, in particular to a composite reactive black dye mixture and its application. Background technique [0002] In recent years, the use of composite reactive dyes has become more and more extensive, and the mixing of different reactive dyes can play a synergistic effect. In addition to good dyeing strength, the current requirements for dyes should also show good high reactivity. KN-B reactive black dye is widely used due to its low price, good fastness, high color fixing rate and easy washing. However, KN-B reactive black dyes have defects such as poor lifting power and insufficient blackness, which limit its further use. The invention provides a composite reactive black dye mixture, which has high reactivity, good color fixation rate and high fastness, and also makes up for the poor lifting force and jet blackness of KN-B reactive black dye. Not enough defects, suitable for cotton fiber dyeing and prin...
