The effect of cationic modification of cotton fabrics, using cationic agent (Chromatech 9414) on direct dyeing characteristics was studied in this work. Cationization of cotton fabric at different conditions (pH, cationic agent concentration, temperature and time) was investigated and the optimum conditions were determined . Nitrogen content of cotton samples pretreated with cationic agent was ...
