防寒用被服材料の圧縮特性と熱特性の関係

抄録

A main purpose of winter coats is to keep body warm, whose performance is related to the thermal resistance of their clothing materials. The coefficient of equivalent overall heat transmission, K_r, is measured and studied in relation to compressional properties for five kinds of material groups (fur, imitation fur, packing fabric, woven fabric, and leather). The material group of larger thickness generally results in smaller value of K_r, i.e., larger thermal resistance. However, samples in each group, especially in fur, shows rather a great scatter from the average trend. Closer relations are found between K_r and other compressional properties, and the relevant property depends on the kind of material because of great difference in the structure.
