Abstract

Thermal manikins are useful tools to study the clothing comfort and environmental ergonomics.
The simulation of sweating can be achieved by putting a highly wicking stretchable knit fabric “skin” on top
of the manikin. However, the addition of such a fabric skin makes it is difficult to accurately measure the
skin surface temperature. Moreover, it takes considerable amount of time to measure the fabric skin surface
temperature for each test. At present the attachment of temperature sensors to the wet fabric skin is still a
challenge. The distance of the sensors to the fabric skin could significantly influence the temperature and
relative humidity values of the wet skin surface. Hence, we conducted an intensive skin study on a dry
thermal manikin to investigate the relationships among the nude manikin surface temperature, heat losses
and the fabric skin surface temperature. An empirical equation was developed and validated on the thermal
manikin "Tore" at Lund University. The empirical equation at ambient temperature 34 oC is Tsk =34.00-
0.0103HL. This equation can be used to enhance the prediction accuracy on the sweating skin surface
temperature and the calculation of clothing evaporative resistance.
