The human cutaneous sensation on moisture is considered in this paper. This problem is related to the comfort of wearing. The final purpose of this investigation is to clarify the sensory mechanism of the clamminess. As the first step, several factors affecting the clamminess are determined. The results are summarized as follows:
(1) When we touch a damper sample, the skin temperature decreases more than when we touch a dry sample. The reason of this phenomenon is that a damper sample has lower temperature and more heat-capacity. The clamminess of a sample is related to this heat-loss. So, it seems that the clamminess is considerably concerned with sensory of coldness.
(2) It also seems that the clamminess is related to the surface characteristcs of sample. Because, in this study, we recognized the relationship between the clamminess and the coefficient of dynamic friction.
(3) The clamminess is considerably influenced by visual perception, too. The clamminess is connected with optical characteristics of the sample, especially diffusion reflection. The reduction rate of diffusion reflection is related to the clamminess. But, this visual perception for the clamminess is not so sensitive as tactile sensation.
Although we could not dealt with physiological mechanism of this sense, we could find a few factors and a few sensory receptors for the clamminess.
