Sažetak
The most important phase in textile finishing processes is adsorption of chemical substances and compounds on textile materials surface and wettability as well. Interface phenomena happen between liquid and solid phase, like water solution and textile material, resulting in change of textile material surface free energy. Electrokinetic phenomena, as zeta potential and specific amount of surface charge, characterize electric charge of textile material. In this paper woven cotton fabrics were enzymatically desized, alkali and enzymatically scoured with alkali and neutral pectinases. The influence of these pretreatments to cotton fabric interface phenomena was investigated throughout the change of fabric surface free energy, zeta potential, Isoelectric Point, Point of Zero Charge, and specific amount of surface charge. It is well known the fabrics treated in wet conditions undergo some structural changes ; therefore the degree of polymerization, DP for cotton cellulose was determined.
