Some open questions of evaluation of comfort properties of functional clothing

In the paper, several relatively new aspects of testing of functional clothing are discussed, such as the effect of moisture and testing time on water vapour permeability of fabrics as well as the effect of the testing time on thermal resistance value of fabrics tested in Skin Model type testers. Also the difference between thermal resistance and thermal absorptivity of fabrics was explained. It was concluded, that there are still some unsolved problems in the above areas, which should attract the attention of textile scientists and technologists.
