High-fastness reactive orange dye composition

Abstract

The invention discloses a high-fastness reactive orange dye composition which is prepared from the following components in parts by mass: 15-35 parts of a component A, 16-25 parts of a component B, 20-35 parts of a component C, 10-25 parts of a component D, 10-28 parts of a component E and 10-18 parts of a component F. The reactive orange dye composition has the advantages of being stable in performance, high in solubility, high in fixation rate, good in dyeing synchronism, good in leveling property, good in tone reproducibility and particularly outstanding in deep color dyeing.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a high-fastness reactive orange dye composition. 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 reactive orange dye 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 high fastness reactive orange dye composition with stable performance, high solubility, high color fixation rate, good dyeing synchronization, good ...
