AB - The purpose of this study was to measure temperatures of cotton and polyester woven fabrics in wetting
and drying process by thermocouples placed on them. It also discussed temperature distribution caused
by diffusion and evaporation at different relative humidity. The measurement points of thermocouples
were located at two concentric circles with radius of 3 cm and 6 cm. The temperatures were measured by
covering the same fabric when a droplet of water dropped on the center of circle at 20%RH, 65%RH and
80%RH environmental moistures, respectively. The results showed that because of diffusion determined
by distance, it was different of temperature changes of every point. As the center of circle, at different
humidity, temperatures when reached dynamic heat balance were different. The drying process of cotton
showed consistency with temperature recovery. At 20%RH, it is the shortest for temperature returning
to environmental temperature because of diffusion speed caused by steam content of environment. It
can be applied to performance assessment for fabrics that liquid water absorbing function is required. It
also can be used for evaluation of discomfort of wet fabrics by temperature decline with the wetting.
