利用电加热人体模型研究了服装设计和织物类型对服装和套装隔热（clo）值的影响。采用各种斜纹棉布设计的夹克和裤子（321.8平方米/盎司），以及其他3.5平方米/盎司的斜纹棉布设计的衬衫和裙子（321.8平方米/盎司）。选定的设计也采用了其他面料。测量每件衣服和套装的衣服重量、衣服面积系数和衣服覆盖的体表面积。结果表明，织物隔热对服装隔热性能有影响，但对所有设计的影响程度不同。设计的变化改变了身体表面积的大小，以及合身的松紧度，从而导致了服装隔热性能的重大变化。 回归分析表明，一件衣服覆盖的体表面积是一个很好的绝缘预测因子，但对于整体来说，这种关系不强。单是体重并不能很好地预测衣服的隔热性。ASHRAE公式用于从服装Icl值之和估算整体的Icl值，是整体隔热的一个相对较好的预测因子。然而，ASHRAE的服装clo值列表需要修改，以包括更多的设计和面料变化。引文:ASHRAE Transactions，1983年，第89卷，pt。华盛顿特区2A。

An electrically heated manikin was used to study the effects of garment design and fabric type on the thermal insulation (clo) values of garments and ensembles. Various designs for shirts, skirts, trousers, suit jackets, and other garments were constructed using three fabrics of 6.1, 9.5, and 14.7 oz/yd2(205.8, 321.8, and 498.1g/m2) cotton twill. Selected designs were also constructed of other fabrics. Clothing weight, clothing area factor, and the body surface area covered by clothing were measured for each garment and ensemble. The results indicated that fabric insulation affects clothing insulation but not in the same degree for all designs. The design variations which altered the amount of body surface area covered and the looseness or tightness of fit produced the major changes in clothing insulation. Regression analysis indicated that the amount of body surface area covered by a garment was a good predictor of insulation, but the relationship was not strong for ensembles. Weight alone was not a good predictor of clothing insulation. The ASHRAE formula for estimating the Icl value for an ensemble from the sum of the garment Iclvalues was a relatively good predictor of ensemble insulation. However, the ASHRAE list of garment clo values needs to be revised to include more design and fabric variations.
