Reactive dye mixture

Abstract

Relating to the technical field of dyes, the invention provides a reactive dye mixture to solve the problems of easy staining, low solubility and undesirable color fastness of printing navy blue and black dyes during washing. The reactive dye mixture is made of, by weight, 1-80% of a dye A, 20-99% of a dye B, and 0-50% of a dye C. The dye has excellent dissolution performance, is easy to wash off and difficult to stain each other, and has excellent perspiration fastness, washing fastness and rubbing fastness, as well as good color paste storage stability, thus being very suitable for printing of cellulose fiber, and the steaming or baking curing process.

Description

technical field [0001] The invention relates to the technical field of dyes, in particular to the preparation of a reactive dye mixture. Background technique [0002] Among the reactive printing dyes, navy blue and black are the ones with a large amount of consumption. The three primary colors of traditional printing dyes are reactive brilliant orange K-G, reactive red K-2BP (C.I.Reactive Red24), and reactive dark blue K-R (C.I.Reactive Blue13). Navy blue and black can be obtained by mixing. Although the color paste is stable in storage, the bright orange K-G stains the white ground more seriously when washed with water, and the bright orange K-G and dark blue K-R have low solubility, so it is not easy to stain when washed with water. Printed navy blue and black dyes with stable storage and good color fastness have become the goals of various dye companies. [0003] Publication number is that the Chinese patent of CN101100559B discloses a kind of composite reactive black pr...
