Active yellow dye composition

Abstract

The invention provides an active yellow dye composition which comprises the following components in percentage by mass: 0.1-99% of one or more than one components A with the structure as shown in formula (I), 0.1-99% of one or more than one components B with the structure as shown in formula (II) and 0-99% of one or more than one components C with the structure as shown in formula (III). The active yellow dye composition of the invention has high dye-uptake and color fixing rate, good promotion performance, levelling property and dyeing stability, bright and rich color and favorable dyeing performances when being applied to dying cellulose fiber, polyamide fiber and textiles thereof.

Description

A kind of reactive yellow dye composition (1) Technical field The invention relates to a reactive yellow dye composition suitable for dyeing cellulose fibers or materials containing cellulose fibers. (2) Background technology At present, the direction of the development of new reactive dyes is how to make them have a high degree of dye uptake and color fixation. Because reactive dyes with high dye uptake can reduce the amount of dye contained in wastewater after dyeing, and high color fixation value can simplify the traditional dyeing process "soap elution process" related to fiber reactive dyes, making the whole printing and dyeing The time is reduced and the cost of printing and dyeing is reduced. As a color species with a large amount of consumption, yellow reactive dyes not only require bright shade, high dyeing rate and fixation rate during dyeing, but also have good color fastness, compatibility and dyeing stability. Currently many commonly used yellow reactive dy...
