Abstract

The invention provides a preparation method and application of a yellow reactive dye combination, and fiber or fiber fabrics dyed with the yellow reactive dye combination, and belongs to the field of reactive dye. The dye combination is composed of, by weight parts, 30-60 parts of a component A shown in a formula (I), 30-60 parts of a component B shown in a formula (II), 1-10 parts of a component C shown in a formula (III), and 0-60 parts of auxiliaries. The yellow reactive dye combination is applicable to dyeing various fibers and fiber fabrics and can obtain excellent color fastness performance.

Description

technical field [0001] The invention relates to a printing and dyeing method suitable for cotton, wool, regenerated fiber or their textiles, or polyamide fiber, cellulose fiber, protein fiber or their textiles, especially suitable for cellulose fibers and their textiles A yellow reactive dye composition for printing and dyeing belongs to the field of reactive dyes. The present invention also relates to the preparation method and application of the yellow reactive dye composition, as well as the fiber or fiber textile produced by printing and dyeing thereof. Background technique [0002] With the continuous increase of fiber varieties and the continuous development of dyeing technology, people have higher and higher requirements for textiles, which poses a great challenge to the improvement of the application performance of reactive dyes. As a color with a large market share, reactive yellow not only requires good light fastness, washing fastness, level dyeing and dyeing rep...
