Abstract

The invention provides an active red dye composition which mainly comprises 0.1-99% of by weight of one or more than one component A represented by the structural formula (I), 0.1-99% of one or more than one component B represented by the structural formula (II) and 0.1-99% of one or more than one component C represented by the structural formula (III) by mass. When being used for dyeing cellulose fiber, polyarmide fiber and fabrics thereof, the active red dye composition has the advantages of high dye uptake rate and color fixation rate and good lifting property, leveling property and dyeingstability, and various dyeing properties are excellent.

Description

(1) Technical field [0001] The invention relates to a reactive red dye composition suitable for printing and dyeing nitrogen-containing or hydroxyl-containing fiber materials. (2) Background technology [0002] 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. [0003] Red reactive dyes, as single-color varieties with large consumption and important compounding components, not only require high dyeing rate and color fixation rate, but also have good color fastness, compatibility and dyeing stability. Currently many commonly used red reactive dye va...
