Abstract:

In order to maintain outdoor body thermal comfort, cold protective clothing with adjustable thermal insulation property is needed to meet their demand under condition of different activities or ambient temperature changes. Thermal insulating property of air inflatable clothing was evaluated in this study. The total and local thermal insulation of the air inflatable clothing was examined by thermal manikin "Newton" in four air inflating volumes and three air speeds. The results reveal that the local thermal insulation in the chest, abdomen and back as well as the total thermal insulation of upper body are significantly greater in the inflated clothing than in the uninflated clothing, but the air inflation volume has no significant effect on the thermal insulation. Meanwhile, the local and total thermal insulation of the air inflated clothing significantly decreases with the increasing of the air speed, and no significant difference is observed between the clothing with different air inflation volumes. This study shows that air inflatable clothing can be used as an effective strategy to dynamically adjust the clothing thermal insulation.

Key words: air inflatable clothing, total thermal insulation, local thermal insulation, air inflation volume, cold protective clothing
