Abstract
This paper deals with the sticky sensation caused by walking derectly barefooted on the floor. In our country that is in the custom of walking directly barefoot on the floor, it feels sometime the sticky sensation in hot and humidy day. The contacting condition between floor and the sole of a barefoot, a evaporation rate of sweet from the sole and humidity between floorcoverings and the sole were measured. The water absorption of floorcoverings and friction coefficient between silicon rubber and floorcoverings were measured as the index of sticky sensation. As a result, the sticky sensation of floorcoverings feel severely in higher temperature and humidity. And the sticky floorcovering has how water absorption and high fricion coefficient. The sticky sensation of floorcoverings can be evalusted by the sticky index calculated with water absorption, friction coefficient of floorcoverings and the evaporation rete of sweet form sole.
