Abstract

The invention discloses a brown dye. The brown dye comprises the following materials in percentage by weight: 50%-90% of a component A and 10%-50% of a component B. The brown dye disclosed by the invention has the advantages of stable performance, high solubility, high color fixation rate, good dyeing synchronization, good level-dyeing property, good color reproducibility, and especially obvious deep-color dyeing performance.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a 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. A large amount of sewage is produced in the existing brown dye 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 brown dye, the synergistic effect of the composite dye makes it stable in performance, high in solubility, high in color fixation, good in dyeing synchronization, good in level dyeing, and good in tone reproducibility, especially for dee...
