Analysis of the oxidation of cellulose fibres by titration and XPS
Lidija Fras,Leena-Sisko Johansson,P. Stenius,Janne Laine,Karin Stana-Kleinschek,Volker Ribitsch +5 more
TL;DR: In this article, the effect of selective oxidation on the surface properties of cotton cellulose fibres was evaluated using four different methods: potentiometric and conductometric titrations, polyelectrolyte adsorption and X-ray photoelectron spectroscopy (XPS).

Topochemical modification of cotton fibres with carboxymethyl cellulose
TL;DR: In this article, carboxymethyl cellulose (CMC) was used as a method to introduce charged groups onto cellulose cotton fiber surfaces, and the amount of adsorbed ionizable groups was determined indirectly by analysis of CMC in solution by the phenol-sulphuric acid method and directly by conductometric titration of the fibres.

The effect of adsorbed carboxymethyl cellulose on the cotton fibre adsorption capacity for surfactant
TL;DR: In this article, 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 advertisersorption can be restricted to the fibre surface.

Estimation of the surface energy of chemically and oxygen plasma-treated regenerated cellulosic fabrics using various calculation models
TL;DR: In this paper, three commonly used methods of estimating apolar, polar, and acid/base contributions were applied: geometric mean (GM), using diiodomethane (MI) and water as probes; van Oss-Good-Chaudhury (vOGC), using MI, tetrahydrofuran (THF), and chloroform (CF); and Owens-Wendt-Rabel-Kaelble (OW), using water, MI, THF, CF, ethanol and ethylene glycol.
