  • In order to produce black disperse dye which has high heat resistance and depth color for polyester(PET), an orange disperse dye was designed and synthesized with pyridine based derivatives to get high heat resistance. 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 $0.7{\mu}m$. 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.
