INVESTIGATION OF THE EFFECT OF CATIONIZATION PROCESS ON WASTEWATER CHARACTERIZATION, PHYSICAL AND FASTNESS VALUES OF COTTON FABRIC

Reactive dyeing is the most widely used method for cellulosic fabrics in textile industry. In this study, it was aimed to reduce environmental impact caused by use of high salt during with reactive dyestuffs. context, a quaternary ammonium based chemical cationization cotton fabrics. The usage amount cationizing agent and flake caustic determined experiments as 50 g/L 17 g/L, respectively. Conventional salt-free standard fabric cationic were carried out 8 different 1% dyestuffs laboratory. As result dyeing, observed that color strength at least conventional dyeing. Pilot-scale trials conducted black color, commonly dye production. Two processes, fabric, using 7% dyestuff. findings revealed has 8.6% darker than fabric. Fastness values similar both Total Dissolved Solids (TDS) value bath 74.4 % lower Similarly, conductivity 73% Chemical Oxygen Demand (COD) 27.8% when compared results. At end these studies, been seen same can be obtained less dyestuff process waste water load reduced.
