Abstract

A red reactive dye composition and its preparation method and application, the red reactive dye composition comprises component A shown in formula (I), component B shown in formula (II) and / or represented by formula (III) Component C shown, and optional auxiliaries. The red reactive dye composition of the invention is applied to dyeing or printing hydroxyl-containing or nitrogen-containing fiber materials such as cellulose fibers and protein fibers, and has excellent color fixing rate and various color fastness properties.

Description

technical field [0001] The invention relates to a red reactive dye composition and its preparation method and application. Background technique [0002] At present, the direction of the development of new reactive dyes is how to make them have a high degree of dye uptake and color fixation. Because reactive dyes with high dye uptake can reduce the amount of dye contained in wastewater after dyeing, and high color fixation value can simplify the traditional dyeing process "soap elution process" related to fiber reactive dyes, making the whole printing and dyeing The time is reduced and the cost of printing and dyeing is reduced. Red is one of the most widely used color systems in reactive dyes. In addition to being used alone for printing and dyeing of textiles, it can also be used as a compound component for blending reactive blue, reactive black and other popular varieties. It not only requires bright color and fast color High, and should have good color fastness, compati...
