Sažetak
Adsorption mechanism of surfactants, dyes, optical brighteners and other agents depends on interaction forces between fiber surface and ionic species. Among other properties very important are electrical properties of fabric surface such are electrokinetic propertys characterized by zeta potential and specific quantity of surface charge. In this work zeta potential, z, Isoelectric Point, IEP (pH value at which fabric has zero zeta potential) and Point of Zero Charge, PZC (amount of cations added to obtain zero zeta potential at a particular pH) were studied, as well as specific quantity of surface charge, q. Electrokinetic properties of standard adjacent fabrics (SDC Products ; use for BS EN ISO 105 F02) - Cotton (Limbric), Wool, Viscose Rayon, Polyamide 6.6 (Nylon f03), Polyester (Terylene) and Acrylic were investigated. Electrokinetic potential was measured by streaming potential/current method using a Brookhaven-Paar electrokinetic analyzer (EKA), with a rectangular cell. Specific quantity of surface charge was calculated after back-titration method, applying Mütek's Partical Charge Detector (PCD 02).
