Abstract

The invention provides a compound active brown dye, which is characterized by being formed by compounding the following components in parts by weight: 18-25 parts of a dye represented by the structural formula (I), 16-18 parts of a dye represented by the structural formula (II) and 55-66 parts of a dye represented by the structural formula (III). The solubility of the three components of the compound active brown dye are similar and the three components belong to intermediate temperature types when being used for dyeing the cellulose fiber material, and dyeing curves are similar; the appetency, the dye-uptake and the fixation rate to the fibers are more similar; the sensitive degrees to a bath ratio and a dyeing temperature of electrolyte salts and color fixing agent alkalis are more similar; and the compound has the excellent dyeing synchronism and leveling property, higher fixation rate and outstanding deep dyeing performance, and effectively overcomes the defects of active brown K-B3R, so that the dyeing quality of the cellulose fiber material is importantly ensured.

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...
