SUN-RESISTANT GREEN LIQUID DISPERSE DYE AND PREPARATION METHOD THEREFOR

The present invention belongs to the field of dyes, and particularly relates to a sun-resistant green liquid disperse dye and a preparation method therefor. The formula of the sun-resistant green liquid disperse dye of the present invention comprises the following components, in percentages by weight: 5-24% of a yellow dye, 6-25% of a blue dye, 9-11% of a composite dispersing agent and the balance of water, wherein the sum of the weight of the yellow dye and the blue dye accounts for 28-32% of the total weight of the sun-resistant green liquid disperse dye. The sun-resistant green disperse dye of the present invention overcomes the defects of serious wastewater pollution, dust pollution, etc., of a powdery disperse dye, has good color fastness to sun, and also enriches green varieties lacking in disperse dyes.
