Abstract

The invention discloses a yellow alkaline dye bath composition. The yellow alkaline dye bath composition comprises disperse yellow dye and a quaternary ammonium salt accelerant. By selecting the specific alkaline resistant dye and the quaternary ammonium salt accelerant, the yellow alkaline dye bath composition realizes a dyeing process of splitting of superfine polyester fibers and alkaline dye bath, greatly shortens a printing and dyeing process of the superfine polyester fibers, improves the rate of dye-uptake of the yellow disperse dye applied to the superfine polyester fibers, and improves color fastness to rubbing and fastness to washing.

Description

technical field [0001] The invention belongs to the technical field of dyes, and relates to a yellow basic dye bath composition and its use, in particular to a yellow basic dye bath composition and its use for short-process printing and dyeing of superfine denier polyester fibers. Background technique [0002] At present, artificial synthetic fibers occupy the mainstream in high-end fabrics, and polyester fibers account for two-thirds of artificial synthetic fibers. The dyes used in polyester fiber printing and dyeing are disperse dyes. Usually, polyester fiber printing and dyeing is carried out under high temperature and high pressure conditions, and most of the dyeing baths are weakly acidic. Since the molecular structure of most disperse dyes contains groups such as hydroxyl, ester, ether, cyano and amide groups, these groups are easily hydrolyzed under high-temperature alkaline conditions, resulting in dyeing performance such as shade and color fastness. Poor, poor rep...
