Abstract

A sodium chlorite bath for the bleaching of textile fibers, e.g. cotton, is activated by one or more bisulfite derivatives of an organic-reducing compound having one or more aldehyde or ketone functional groups and which are capable of forming bisulfitic combination addition compounds with an alkali bisulfite. Such activators have been found to be effective in bringing about the progressive decomposition of the sodium chlorite of the bath and hence controlled bleaching at relatively low temperatures of the sodium chlorite bath.
