The effects of physical properties on wear comfort and microclimate between cloth and skin under exercise were studied using Nylon and modified nylon.1. ExperimentsExperiments were conducted in a climatic chamber under the condition of 22.7^ﾟC, 11.0% A. H. 10cm/sec of air movement. A subject took a 21 minutes exercise on the treadmill. Local temperature and vapor pressures were measured inside and outside of the fabrics at chest and back. Pulse rate, oral temperature, mean skin temperature and body weight loss were measured during experiment. The subject marked a ballot to communicate her sense of sweating soaking thermal sensation and comfort sensation.2. ResultsMicroclimates were similar in temperature, whereas different in humidity. Absolute humidities of microclimate in the sample N clothed subject were higher than those of microclimate in the other fabrics. Sense of sweating and thermal sensation closely related to temperature and vapor pressure between cloth and skin. Body weight losses were similar in absolute humidities of microclimate between cloth and skin.
