Comparison of subjective and objective measurement of sweat transfer rate.

ABSTRACT

Sweat absorption is investigated using the subjective and objective methods. The subjective investigation analyses the physiological responses of male and female volunteers wearing two kinds of textile fabrics (cotton and polyester) during certain physical activity. The subjects were exposed to the different conditions of ambient temperature (23, 26, 29 and 32 degrees C) and constant relative humidity of 67 +/- 3%. In the objective investigation the sweating guarded hotplate (SGHP) system was used that stimulates the processes of sweat transfer between the human skin, textile material and environment. The results of mass absorption obtained from the objective measurement on the sweating guarded hotplate show the similar trend as the results obtained during the subjective measurement.
