Combination of wet fixation and drying treatments to improve dye fixation onto spray-dyed cotton fabric

Abstract The conventional dyeing process requires a substantial amount of auxiliaries and water, which leaches hazardous colored effluents to the environment. Herein, a newly developed sustainable spray dyeing system has been proposed for cotton fabric in the presence of reactive dyes, which has the...
