abstract = {The most important parameters characterizing thermophysiological comfort of sport and protective 
garments are thermal resistance, water vapour permeability and air permeability. Contrary to 
common textiles, protective and functional garments and some technical textiles like textile 
dressings are also used in wet state, which affects their comfort properties. However, common 
measuring instruments mostly do not enable reliable measurement of wet fabrics, due to long time 
of measurement, during which the fabrics get dry. In this paper two fast measuring PC evaluated 
instruments ALAMBETA and PERMETEST commercial instruments are described, which provide 
reliable non-destructive measurement of thermal conductivity, thermal resistance and water 
vapour permeability of fabrics in dry and wet state. By means of these instruments, thermal 
resistance and water vapour permeability of heavy cotton and cotton/PES woven fabrics in wet 
state were experimentally determined and results were discussed. The effect of structure and 
composition on the above-mentioned properties of these fabrics has been investigated as well. 
Some surprising results were achieved: with increasing fabrics humidity, the air permeability 
almost linearly decreased, whereas the total cooling heat flow (due to water evaporation from the 
wet fabric surface) slowly increased.},
