In order to explore the utilization of persimmon juice-dyed T-shirts under vigorous sports activities, persimmon juice-dyed and undyed cotton knitted T-shirts were compared in terms of comfort-related physical properties such as moisture transport characteristics and wear performances including sweat amount, moisture uptake of clothing, and subjective sensation such as thermal, humidity, and overall comfort. As results, persimmon juice-dyed T-shirt material showed the improvement of air permeability, water-vapor permeability, and moisture regain while it gave lower values for wickability and dynamic water absorption rate than undyed one. As for wear performance under a vigorous activity, human subjects seemed to sweat less in wearing dyed shirts than in undyed ones, which means that persimmon juice-dyed shirts seemed to give less physiological heat stress than undyed ones. Subjects felt no difference between dyed and undyed shirts in subjective sensation, hence it could be said that, under a vigorous condition, persimmon juice-dyed shirts could not provide subjective sensory differences from udyed ones.
