The alkaline hydrolysis of 11 vinylsulfonyl (VS) reactive dyes (F-type) fixed on cellulose was examined at 50 degrees Centigrade and pH 10.9. The reversibility of the dye-fiber bond was verified by the cylindrical-film-roll method using dyed and undyed cellophane. The F-types decomposed to yield the VS types, which were further hydrolyzed to yield the hydroxyethylsulfonyl types or reacted with cellulose to re-form the F-types. The F-types were composed of two species, presumed to arise from the initial VS reaction with cellulose 6-OH or 2-OH, which showed fast and slow rates of bond scission.
