The efficiency of (3-chloro-2-hydroxypropyl)trimethylammonium chloride and polyamino chlorohydrin quaternary ammonium compound for cationization of cotton has been studied. The influence of process conditions during cationization on the colour strength (K/S) and total dye utilization has also been studied. It is observed that the cationization increases the dye utilization by 30% with no change in colour fastness and reduces the environmental pollution to a great extent. Cationized cotton dyeing is found to consume only 40% steam and 50% time to that of normal dyeing. Cationization with (3-chloro-2-hydroxypropyl)trimethylammonium chloride is found to be a successful and commercially-viable process which ensures 17% saving in dyeing cost.
