Dyeing of Polyester/cotton Blends with Encapsulated Disperse/reactive Dyes for a One-bath Auxiliary-free Process

摘要

Research on the 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.
