초록
The physical properties of textile materials and thermal physiological responses of the human subjects wereevaluated with 4 different types of the army combat uniforms including US, German, Korean and general uniforms forthis study. 8 male adults were used as the human subjects and the tests were done in the environmental chamber thatwas 25±0.1oC of temperature, 65±5% of relative humidity and below 0.3 m/sec of air velocity. The test protocol consistedthe rest period for 20 min., the exercise period for 20 min., the rest period for 20 min., the exercise period under windcondition for 20 min., and the recovery period for 20 min. The human subjects walked with 4.5 km/hr for 10 min., ran7.5 km/hr for 10 min. during the first exercise period and walked and ran with the same speeds under 3.5 m/sec of theair velocity that simulated outdoor condition during the second exercise period. The test results of the study were as follows;The wind condition affected the skin and microclimate temperature of the human subjects lower compared to withoutwind condition, but had insignificant effect on the humidity control. The low air permeability of Korean uniform causedblocking the elimination of the humidity from the body and the regulation of body temperature. However, Korean uniformscould be the excellent one with the designs considering the ventilation of the uniforms and the textile fabrics with betterair permeability.
Abstract
The physical properties of textile materials and thermal physiological responses of the human subjects wereevaluated with 4 different types of the army combat uniforms including US, German, Korean and general uniforms forthis study. 8 male adults were used as the human subjects and the tests were done in the environmental chamber thatwas 25±0.1oC of temperature, 65±5% of relative humidity and below 0.3 m/sec of air velocity. The test protocol consistedthe rest period for 20 min., the exercise period for 20 min., the rest period for 20 min., the exercise period under windcondition for 20 min., and the recovery period for 20 min. The human subjects walked with 4.5 km/hr for 10 min., ran7.5 km/hr for 10 min. during the first exercise period and walked and ran with the same speeds under 3.5 m/sec of theair velocity that simulated outdoor condition during the second exercise period. The test results of the study were as follows;The wind condition affected the skin and microclimate temperature of the human subjects lower compared to withoutwind condition, but had insignificant effect on the humidity control. The low air permeability of Korean uniform causedblocking the elimination of the humidity from the body and the regulation of body temperature.
