A disperse dye composite contains an orange dye A shown in the formula (I), a purple dye B shown in the formula (II), a red dye C shown in the formula (III), a blue dye D shown in the formula (IV), a blue dye E shown in the formula (V) and a red dye F shown in the formula (VI). The disperse dye composite of the invention can be used to prepare liquid, pasty or powdery products and the like. When the disperse dye composite of the invention is used to dye the polyester fabric and the polyester/spandex fabric, the dyed fabrics which have pure color light, good dispersivity, good wash-fastness, sunlight fastness, perspiration fastness and rubbing fastness, less stain to spandex and a range of color from deep blue to black, can be obtained by adjusting the ratios of different components.
