Oznake: tekstilstvo;bombažna vlakna;modifikacija;karboksimetil celuloza;praktična uporaba;adsorpcija CMC;textile fibres;cotton fibres;modification;carboxymethyl cellulose;acid groups;charge increase;conductiometric titration;phenol-sulphuric acid test;practical applications;
The research reported in this paper demonstrates that the capacity of cotton fibres to adsorb cationic surfactants as well as the rate of the adsorption process can be increased by adsorbing carboxymethyl cellulose (CMC) onto the fibre surfaces; in addition, the adsorption can be restricted to the f ...

The purpose of this study was to evaluate the effect of selective oxidation on the surface properties of cotton cellulose fibres. Four different methods to evaluate the accessibility, nature and content of ionisable acidic groups (charge) in the fibres were applied: potentiometric and conductometric ...

Adsorption of fucoidan and chitosan sulfate on chitosan modified PET films monitored by QCM-D
Tea Indest, Janne Laine, Leena Sisko Johansson, Karin Stana-Kleinschek, Simona Strnad, Renate Dworczak, Volker Ribitsch
Izvirni znanstveni članek
Oznake: PET films;fucoidan;chitosan sulfate;adsorption;anticoagulant properties;
The adsorption behavior of fucoidan as well as chitosan derivatives (chitosan sulfate) on poly(ethylene terephthalate) (PET) model film surface was studied using the quartz crystal microbalance technique. These systems were chosen for this study due to their promising biocompatible properties. Moreo ...
