Abstract:

In order to study the distribution characteristics of local skin moisture sensitivity of human under thermal environment and the relationship between objective physical humidity and human subjective moisture feeling, the body fitted one-piece experimental clothes were made of elastic knitted fabric for tests in the artificial climate cabin (the temperature is (30±1) ℃ and the relative humidity is (35±1)%). Six female subjects wore the experimental clothes and walked on the treadmill at the speed of 5 km/h. The objective physiological data and subjective evaluation data of the subjects were recorded during the experiment. The results indicated that the moisture sensitivity of human skin has some local distribution characteristics in the thermal environment. The high sensitivity areas were the upper forehead, chest and lower back, the medium sensitivity areas were upper arm, anterior abdomen, upper back, forearm and buttocks, and the low sensitivity areas were calves and thighs. The experiment confirmed that the skin humidity perception increased with the increase of physical humidity, and there was a positive correlation between humidity perception and physical humidity.

Key words: moisture sensitivity, clothing comfortability, perception of wetness, physical humidity, elastic knitted fabric
