Sažetak
Interface phenomena have a significant role in wet finishing processes of cotton. Therefore, interface phenomena of cotton fabric, cationized with commercial cationic compound, were studied in this paper. The characterization of surface after cationization, was performed by FTIR-ATR and SEM. Interface phenomena were studied through electrokinetic phenomena, surface free energy and adsorption. Zeta potential, Isoelectric point (IEP) and Point of zero charge (PZC) were determined according to streaming current/streaming potential method ; specific amount of surface charge and adsorption of a ionic surfactant by potentiometric titration method ; surface free energy by thin layer wicking method. The affinity of such modified cotton for reactive dyes having different functional groups was investigated through the K/S values. The effect of electrolyte addition on dye bath was investigated as well.
