Disperse blue dye adopts heterocycles structure for high molar extinction coefficient and long wavelength absorption. Synthesized disperse dye is micronized to an particle size of 0.7㎛. The mixing condition for black color using commercial disperse violet 93 is blue dye 30%, red dye 21%, and orange dye 21%, respectively. Dyed PET fabric with synthesized dye has quiet good color fastness to sublimation(grade 3-4) and has excellent rubbing, washing and light fastness grade 4-5.
