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
