▎ 摘  要

NOVELTY - The method comprises (1) mixing the multiple dyes and stirring uniformly, where the dye concentration is 1.2-3.2 wt.%, (2) adding 0.2-1.5 g/l dispersant, 0.5-1 g/l leveling agent and 0.1-1 g/l of graphene oxide, (3) dyeing the fabric according to ratio of 1: 5-6, where the multi-dye comprises red dye, yellow dye, and/or blue dye, the red dye is cochineal extract, yellow dye is Gardenia extract, and the blue dye is blueberry extract.. USE - Method for improving dyeing fastness by multi-dye mixing. ADVANTAGE - The method: realizes two fiber dyeing in one bath; removes the reduction cleaning and post-processing step, which improves the production efficiency; saves the water resource and the consumption of other energy, and realizes uniform dyeing; has higher solarization fastness, and washing fastness.
