Adsorption of chitosan solution as well as chitosan nanoparticles dispersion onto cellulose fibres was implemented at pH = 4 and 7, respectively, in order to investigate the influence of different pH values on chitosan macromolecules' conformation and consequently on its adsorption ability and resultant coating morphology, as well as on antimicrobial activity of coated fibres. Adsorption capacity, charging behaviour and electrokinetical response of fibres at different pH values were analysed by determining zeta potential. Obtained results were related to the antimicrobial activity of fibres, determined by standard ASTM E2149 method.
