Sažetak
Cotton is modified in pre-treatment finishing processes and its physical properties are changed. The intensity of these changes depends upon the conditions under which processing is done. The properties obtained are the results of chenges in micro and macro structure of the cotton treated fibers. The structural differences of the modified cotton, besides other properties, results also in changes of electrical charge of its surface. This paper deals with the influence of scouring, bleaching and mercerization on the electrokinetic potential of cotton fibers expressed as zeta potential. It is measured as dependent upon the pH of the electrolyte solution, as well as upon the quantity of surfactant added in the purpose of obtaining the point zero charge (PZC) of the fibre surface.
