Obsah Individual preparation and tuition according to given particular plan intended lecturer, regular lecture don't do. Individual study of selected parts from these topics: Sorption of dyes into fibers, theory of textile dyeing, relationship between fiber and dyestuff structure and the dyeability. Dyeing equilibrium, Enthalpy, entropy of dyeing. Affinity of dyestuffs. Langmuir, Freundlich, Nernst and BET isotherms. Kinetics of dyeing. Sorption of liquids into textiles. Wetting phenomena in textiles, chemical and physical aspects, intermolecular forces on interface, measurement of contact angles on fibers and textiles, apparent contact angle, wicking in textiles - equilibrium and kinetics, influence of textile structure. Variation of the diffusion coefficient. Physical-chemical principles of textiles hydrophobic and oleophobic finishing. Creation of thin layers on fibres.
