Dyeing of Polyester/Cotton Blends with Encapsulated Disperse/Reactive Dyes for a One-Bath Auxiliary-Free Process

Research onthe one-bath dyeing process of encapsulated disperse dyes and reactive dyes on polyester/cotton blends showed that through the suitable modification before dyeing, polyester/cotton blends could be dyed with encapsulated disperse/reactive dyes in an auxiliary-free, one-bath method. The dyed goods attained excellent levelness and fastness. The residual dye in the final baths were very low. Thus, cleaner dyeing production and environment protection can be realized.
