Abstract
The invention discloses a disperse blue-to-black dye composition. The disperse blue-to-black dye composition is obtained by mixing of original dye and auxiliary agents. The original dye comprises 40-99wt% of an ingredient A and 1-60wt% of an ingredient B. The ingredient A comprises one or more materials shown in the formulas (I)-(II) and the ingredient B comprises one or more materials shown in the formulas (III)-(V). The disperse blue-to-black dye composition has a wide pH-resistant range and excellent various fastness, has stable color and gloss in a strong base bath, is a hard-won strong base-resistant disperse dye and can be used for alkaline burnt discharge.
Description
(1) technical field
The present invention relates to a kind of disperse dye composition, be specifically related to a kind of EX-SF DISPERSE BLUE EX-SF 300 to black dye composition.
(2) background technology
Polyester piece good pre-treatment is carried out in the basic conditions, and what generally adopt in terylene disperse dyeing process is dye under acidic conditions, therefore to need before dyeing first and with abundant washing, make whole wet treatment longer for process period like this.And if refining or alkali decrement treatment improper, or wash insufficient and be with alkali time, dyeing under acidic conditions often there are quality problems, and reproducibility is poor.So the dispersed dye dyeed under being suitable for alkaline condition if can find, will make that dyeing process is simpler and more direct, dyeing is more reasonable.This is factory's energy-saving and emission-reduction, reduces costs and establish good basis.Meanwhile, the oligopolymer traditional acidic conditions dyeing also can being avoided often to occur stains the disadvantage such as specking, color dot, dyeing flower caused.
In addition, the burn-out printing of conventional fabrics utilizes the differences such as the acidproof of fiber or alkali resistance, removes the working method of wherein a kind of fiber with acid or alkali.The alkaline burn-out printing of polyester flannel woven fabrics utilizes the alkali hydrolyzable of trevira, by controlling the local hydrolysis of terylene matte, develops a kind of matte in stereo concave-convex effect.Because the alkali resistance of dispersed dye is not good enough, too responsive to pH value, easily produce cylinder poor, unstable product quality, upper dye can not be stablized in highly basic (as NaOH) system.Therefore, seek that every fastness is excellent, the alkali-resistant disperse dye complex of good level-dyeing property is the significant work of item.
