Abstract

The invention relates to a composite type reactive dye composition, which is characterized in that the composition is formed by mixing four kinds of reactive dyes A, B, C and D in percentage by mass: 50 to 100 percent of dye A, 0 to 50 percent of dye B, 0 to 50 percent of dye C, 0 to 50 percent of dye D, and the balance is auxiliaries, and the structure general formulas of the four kinds of reactive dyes A, B, C and D are respectively (1), (2), (3) and (4) shown as the accompanying drawing. The composite type reactive dye composition has better compatibility, the dyeing process is easy to control, and good dyeing stability is realized.

Description

technical field

[0001] The invention relates to a composite reactive dye composition suitable for dyeing cellulose fiber or cellulose-containing fiber and a dyeing method using the series reactive dye composition. Background technique

[0002] In the dyeing of cellulose fibers using reactive dyes, it is known to use yellow, red, and blue reactive dyes as dyes for three primary colors, and to blend them in various ratios for dyeing. For the reactive dyes used as the three primary colors, it is required that the dyes have good lifting and level dyeing properties, and the dyeing speed of the three primary colors is basically equal and the temperature dependence is consistent. And the various fastnesses of the three primary colors are excellent. In addition, it is particularly required to be able to meet the needs of the actual process. In the past, the dyes of the three primary colors have different affinity to cellulose fibers, and the dyeing behavior is different. Therefore...
