Abstract

Abstract:

In order to explore the influence characteristics of clothing materials on the cooling effect of mine ventilation clothing, human skin temperature, micro-environment temperature and micro-environment humidity were selected as the evaluation indexes of the cooling effect. Based on the artificial environment test chamber and experimental measuring instruments, the experimental data were collected and analyzed by real-life training experiments under different labor intensities and different ventilation conditions. The cooling effects of three kinds of clothing materials were compared, and the micro-environment climate between the human body and clothing was analyzed. The results show that the cooling effect of three kinds of mine ventilation clothing is modal fiber type > pure cotton type > silica gel type, and the average cooling range is about 2, 1.5 and 1 ℃. The micro-environment temperature and humidity are significantly reduced. The humidity in the micro-environment is pure cotton type > modal fiber type > silicone type, and the temperature in the micro-environment is modal fiber type < pure cotton type < silicone type.

Key words: clothing material, mine ventilation suit, Training test, micro-climate, cooling effect
