A New Approach to the Dyeing of Silk with Sulphatoethylsulphone Dyes

A new approach to the dyeing of silk with sulphatoethylsulphone dyes, based on beta-elimination before dyeing, has been investigated. Some factors affecting both beta-elimination and dyeing have been studied. The improved dyeing process shows a high degree of dyebath exhaustion and excellent fixation in the absence of salt, thus reducing the risk of environmental pollution from salt and dyes
