Abstract:The behavior of a polyfunctional reactive dye containing bis(monochlorotriazine/sulphatoethylsulphone) reactive system on silk has been investigated. The twinned monochlorotriazine/sulphatoethylsulphone reactive system confers a relatively high fixation efficiency of this type of polyfunctional reactive dye even at low salt and/or temperature conditions when compared with that of the conventional bifunctional reactive dye containing one monochlorotriazine/sulphatoethylsulphone reactive system. The results also indicate that the fastness properties are approximately the same for both the reactive dyes under investigation.
