Course content
Content: - Dye sorption into a fibers, theory of textile dyeing, relationship between fiber structure, dyestuffs and dyeability, intermolecular forces - Equilibrium state of dyeing. Enthalpy and entropy of dyeing. Thermodynamically defined affinity of dyestuffs for fibers. Langmuir´s, Freundlich´s, Nernst´s and BET isotherms. - Kinetics of dye sorption. Influence on diffusion coefficient. - Physico-chemical view of the wetting problem, intermolecular forces at the interphase and their prediction - Measurement of contact angles between liquid and polymer in the form of fibers and textiles, apparent contact angle - Textile wicking - equilibrium and kinetics, influence of textile structure. - Absorption of water into the fiber mass

Learning outcomes
Aim of these course is improvement of knowledge of sorption processes in textile structures. Complexity of sorption behavior of fibrous structures is presented on a sorption of molecules into the fiber mass and on sorption of a liquid into the textile structure. Fluid absorption into the fabric is usually accompanied by absorption of molecules into the fiber mass. This aspect is fully incorporated in this broad concept of sorption processes. An integrated view of sorption as one of the most important properties of fiber systems is created in this concept.
The student will acquire detailed knowledge of the subject in the area according to the approval of the Branch Board
