ABSTRACT

　The purpose of this study was to clarify the effects of environmental thermal stimuli on clothing discomfort sensation under different environmental temperature and humidity conditions by investigating changes in physiological and psychological states and fabric conditions when the fabrics get wet and sticks to the human skin. To achieve this purpose, a wearing experiment conducted to investigate the physiological and psychological state of participants after perspiration by exercising for 20 minutes in five environments with different environmental temperatures and humidity levels. Additionally, measurements of fabrics were also conducted to investigate the state of the fabrics in the same environments. The results revealed the following: （1） In a low-humidity environment, the discomfort sensation caused by the cold and wet sensation was observed due to the thermal transfer rate from the fabric was fast; （2）In the thermo-neutral environment, it took longer for the wet fabric to slide, and the sliding resistance of fabric was greater. The physical phenomena of the fabric and the weak thermal stimulation by the environment caused discomfort sensation related to the mechanical elements on skin contact; （3） In the high temperature and humidity environment, the discomfort sensation was expressed by the sensations of stuffiness and stickiness due to the high humidity within the cloths. These results concluded the need to consider the effects of environmental stimuli when examining the clothing discomfort sensation associated with wet and sticky clothing.
