Thermophysiological responses of T-shirts from absorption & quick drying fabrics
The purpose of this study was to investigate the effects of T-shirts made from absorption & quick drying fabric and traditional fabrics on the thermophysiological responses during exercise in environmental conditions. Six male university students performed a 20-min seated rest, 20-min treadmill protocol, and 20-min rest whilst wearing three kinds of short sleeved T-shirts made from evaporative polyester fabric (C-M), traditional 100%cotton fabric (COT), and 100% polyester fabric (POLY). Environmental temperature and relative humidity were (20.0±0.5)℃ and 65.0%±2%, respectively. Clothing microclimate temperatures and relative humidity at three body sites were recorded during the test. And clothing surface temperatures were measured using an infrared imaging camera. Furthermore, subjective ratings on thermal comfort and sweating sensations were collected. It was shown that clothing microclimate temperatures and relative humidity was significantly lower for C-M at the end-exercise when compared with COT and POLY. Mean clothing surface temperatures at front torso were significantly highest in C-M than in COT and POLY. Significant differences in subjective sensations were observed. It was concluded that the different characteristics of fabrics could play a role for sweating physiology in the environmental conditions. The fabric with improved evaporative characteristics tended to regulate skin temperatures better than the traditional fabrics, providing a desired thermophysiological response and thermal comfort.
