The wool dyeing properties, such as exhaustion and fixation parameters, of selected hetero‐bifunctional Sumifix Supra dyes and some other commercial reactive dyes were quantified under various dyebath pH conditions. Studies of the dyeing of wool serge fabric indicated that Sumifix Supra dyes could produce reasonably high fixation values. However, remarkably improved fixation values were obtained when these dyes were pre‐activated to the vinylsulphone form and dyed in this form, especially at low pH values (pH 4 or lower).
