Abstract

The invention provides a yellow reactive dye composition and an application thereof. The dye composition contains one or a plurality of dyes selected from the dyes represented in the following general formula (1), the general formula (2) and the general formula (2) which are mixed in a certain proportion. The yellow reactive dye composition has bright color and luster, good dye fastness and dyeing performance, marked advancement especially on the aspects of improvement rates, fixation rates and compatibility, enhanced fastness to chlorine and excellent easy washing performance and photochromism resistance.

Description

technical field [0001] The invention relates to a yellow reactive dye composition and its dyeing application on fiber materials and wool. Background technique [0002] The US 4,703,112 patent filed by Hoechst in 1987 discloses the structure of a class of yellow reactive dyes. [0003] Representative structures of this class of dyes are: [0004] [0005] Dye I-1 [0006] [0007] Dye I-2 [0008] These dyes are golden-yellow-red-yellow in color and have good color fastness. The practice of application shows that this kind of commercial dye has defects in dyeing application, and it is difficult to meet the increasingly demanding printing and dyeing requirements. [0009] The inventor proposes to modify this type of dye by blending and compounding, that is, compounding it with one or more dyes represented by the following general formula (2), in order to improve some defects in application performance. Practice has shown that although some improvements have been obt...
