Infrared heat radiation was directed onto the backs of healthy female subjects wearing a white or a black dress. Local skin thermal reactions of the back and the thigh were observed with reference to clothing color in a climate chamber where the ambient temperature was set at 20, 25 or 30 degrees C. Heat flow, skin temperature and air temperature under the clothing were measured. In the absence of radiation, skin temperature was higher than air temperature under clothing on the back and the thigh. Heat radiation caused both skin temperature and air temperature under clothing to rise, but the rise was considerably greater with black clothing than with white. As the effect of radiation was indirect, heat flow direction at the thigh was the same as in the absence of radiation. The thermal resistance index was calculated from skin temperature, air temperature under clothing and heat flow. Upon radiation exposure, the index of a black-clothed back tended to decrease with rising globe temperature. On the contrary, the index of a white-clothed back increased from a low negative value. This index is useful in assessing the skin-cloth system.
将红外热辐射照射到穿着白色或黑色连衣裙的健康女性受试者的背部。在环境温度设定为20、25或30摄氏度的气候室内，参照服装颜色观察背部和大腿的局部皮肤热反应。测量了衣服下的热流、皮肤温度和空气温度。在没有辐射的情况下，背部和大腿处衣服下的皮肤温度高于空气温度。热辐射导致衣服下的皮肤温度和空气温度都升高，但黑色衣服的升高幅度比白色衣服大得多。由于辐射的影响是间接的，大腿处的热流方向与没有辐射时相同。根据皮肤温度、衣服下的空气温度和热流计算热阻指数。暴露于辐射后，黑色衣服背部的指数往往随着球体温度的升高而降低。相反，白色衣服背部的指数从较低的负值增加。该指数有助于评估皮肤-服装系统。
