Abstract
A cotton skin and a waterproof but permeable Gore-Tex skin were designed for the thermal

manikin “Tore” to simulate different sweating styles (the wet cotton skin inside and Gore-Tex

skin outside to simulate the sweating style of thermal manikin “Walter”, and Gore-Tex skin inside

with wet cotton skin outside to simulate the sweating style of thermal manikins “Newton”). The

evaporative resistances of two skin combinations with clothing ensembles were compared at different

environmental conditions. In addition, the total evaporative resistance of clothing ensemble was

calculated by both the heat loss method (option 1) and the mass loss method (option 2) according to

ASTM F 2370.... (More)
A cotton skin and a waterproof but permeable Gore-Tex skin were designed for the thermal

evaporative resistances of two skin combinations with clothing ensembles were compared at different

environmental conditions. In addition, the total evaporative resistance of clothing ensemble was

calculated by both the heat loss method (option 1) and the mass loss method (option 2) according to

ASTM F 2370. We found that the effect of different sweating mechanisms on the clothing evaporative

resistance should be considered. The results showed that the total evaporative resistances calculated

by option 2 were more accurate than values in option 1 under the isothermal condition. It was also

found that differences of the total evaporative resistance between two skin combinations with clothing

ensembles decreased with the increasing clothing ensemble layer. In a non-isothermal condition, the

total evaporative resistance calculated by option 1 was more accurate than the value obtained in option

2, which was due to the lower ambient temperature and condensations between each adjacent layer. (Less)
