Abstract

The invention provides a composite reactive brown dye. The dye is prepared by compounding 10 to 40 weight parts of the dye shown in a formula (1), 10 to 20 weight parts of the dye shown in the formula (2) and 40 to 80 weight parts of the dye shown in the formula (3). Due to the synergistic effect of the composite dye, the dye has the advantages of stable performance, high solubility, high color fixation rate, high dyeing synchronization, high level-dyeing property, high tone reproducibility and prominent dark color dyeing and is particularly suitable for printing and dyeing cellulose fiber materials.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a composite reactive brown dye. Background technique [0002] With the continuous development of cellulose fiber varieties and the continuous development of dyeing technology, when using reactive dyes to dye cellulose fibers, higher and higher requirements are put forward for the application performance of reactive dyes, and new reactive dyes with excellent performance are required. dye. An existing similar active brown K-B 3 The dye with R structure has a solubility of only 80g / l, and a large amount of sewage is produced during the dyeing process. After the cellulose fiber material is colored, its lifting force is not enough, the leveling property is not good, and it cannot be dyed in dark colors. Contents of the invention [0003] The invention provides a composite reactive brown dye. The synergistic effect of the composite dye makes it stable in performance, high in solubility, high i...
