Example Embodiment

[0009] Example

[0010] A mixture of 30 grams of Disperse Blue 83, 10 grams of Disperse Blue 87, 15 grams of Blue 62, 40 grams of Disperse Blue 3, 5 grams of sodium lignosulfonate and UV absorber (ratio 1:1) Mix uniformly, then add water to grind and micronize. The slurry after grinding is spray-dried. The spray drying conditions: inlet temperature 120℃, outlet temperature 60℃, and add 10 grams (10%) of nanometer to the dried product Silica to obtain blue high light fastness disperse dye.

[0011] The blue high light fastness disperse dye composition of the present invention has complete chromatograms, is colored on polyester fiber, has excellent color fastness and dyeing performance, the dyed polyester fiber has a wide range of uses, and the light fastness reaches level 5 , Rubbing fastness 4-5, washing fastness 4-5, has quite good dyeing performance, easy to wash.
