통기성 향상을 위한 하계비행복 설계 및 착용쾌적성 평가

Abstract

This study verified the effect of summer flight ventilation developed in a previous study based on wearingcomfort evaluation. Seven healthy males in their twenties volunteered for this experiment conducted in aclimatic chamber. The experiment consisted of three consecutive periods of rest (20 minutes), running on a treadmill (10 minutes) andrecovery (20 minutes). A comparative evaluation was conducted on the general flight suit which had no ventilation holesand summer flight suit that usesubjective satisfaction measures and objective measures. The subjective satisfaction wasevaluated according to the criteria of temperature sensation, wet sensation, thermal comfort and fatigue sensation. Theobjective satisfaction was measured by skin temperature, microclimate (temperature and humidity), sweat rate and thermography. The comparative wearing evaluation identified the summer flight suit decreased the temperature between skinand suit by 0.42oC (upper arm), 0.9oC (calf) and the skin temperature by 0.3oC (shoulder), 0.4oC (upper arm), 0.5oC (calf)as compared to the general flight suit. The humidity inside the summer flight suit decreased at head (7.73%), shoulder(5.86%), upper arm (5.26%), and calf (8.73%) compared to the one inside the general flight suit. Thermography showedthat the air flowed through ventilation holes (neck and armpit). The design of ventilation holes applied to the summerflight suit can be applicable to overall clothing that requires thermal comfort such as dust-free garments, mechanical clothingand combat uniforms.
