Learning activities and teaching methods
Self-study (text study, reading, problematic tasks, practical tasks, experiments, research, written assignments), Independent creative and artistic activities, Individual consultation, Seminár
Learning outcomes
Main aim of this subject is to explain the clothing comfort principles, along with all theoretical knowledge and experimental skills, which will make the student able to design the clothing with required sensorial and particularly thermos-physiological comfort. The student also should learn to operate modern non-destructive methods of determination of comfort of fabrics and clothing and to use the results in marketing of textile products.
The student will acquire detailed knowledge of the subject in the area according to the approval of the Branch Board
Prerequisites
unspecified

Assessment methods and criteria
