Electrokinetic Phenomena of Cationized Cotton and its Dyeability with Reactive Dyes

Interface phenomena have a significant role in the wet finishing processes. Therefore, in this paper electrokinetic phenomena of cotton fabric cationized with commercial cationic compound was researched. After cationization, the characterization of surface and chemical composition was performed by FTIR-ATR. Electokinetic phenomena - Zeta potential, Isoelectric point (IEP) and Point of zero charge (PZC), were determined according to streaming current/streaming potential method and specific amount of surface charge according to back-titration method. The affinity of such modified cotton to reactive dyestuff of different functional groups was investigated trough the K/S values. The influence of electrolyte addition to dye bath was investigated as well.
