使用电加热人体模型研究服装设计、面料类型和测试方法（即单独或作为整体测试的服装）对服装隔热值（ITAN和Iclclo）的影响。结果表明，三种实验织物的100%纯棉斜纹织物除隔热性能外，其他所有纺织性能均存在显著差异。因此，织物重量的巨大差异不一定会导致织物绝缘性能的相应差异。这三种织物的设计变化具有相似的clo值；然而，宽幅衬衫和羊毛西服织物的织物隔热性能的差异导致了服装隔热性能的差异。 织物隔热层似乎会影响服装隔热层，但对所有设计的影响程度并不相同。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。

An electrically-heated manikin was used to study the effects of garment design, fabric type, and test method (.i.e., garments tested individually or as part of an ensemble) on the thermal insulation value (ITand Iclclo) of clothing.The results indicated that the three experimental fabrics of 100% cotton twill were significantly different from each other for all of the textile characteristics except thermal insulation. Consequently, the large differences in fabric weight did not necessarily cause corresponding differences in fabric insulation. Design variations constructed of these three fabrics had similar clo values; however, differences in fabric insulation for the broadcloth shirting and wool suiting fabrics caused differences in clothing insulation. It appears that fabric insulation affects clothing insulation, but not in the same degree for all designs.The ASHRAE list of garment clo values needs to be revised to include more design and fabric variations.
