Abstract
The main steps of cotton pre-treatment process are degradation of non cellulose compounds and oxidation of natural pigments. Practically all purification processes of cotton fibers are questionable, because of their rather high environmental pollution. During these processes the fibrillar structure of cotton is loosened, causing on one side swelling of the polymer as well as increased accessibility of active groups on the fiber surface. It is assumed this modifications of the surface of the solid phase cause mainly changes of the electrokinetic properties and of the interaction with components of liquid phase. The electrokinetic properties could be discussed under the view of the fibers zetapotential, what is the term describing the electrokinetic properties at that position of the solid liquid interface which is accessible for interactions. In this project the surface charge of cellulose fibers is defined as a function of different purification process steps and correlated with following phenomena: - swelling of the fibers, the interaction energy between fibers and surfactants, and the final state of the fiber surface: - the degree of purification, the amount of adsorbed surfactant, the shade of the colour.
