The purpose of this study is to obtain basic data for designing quilt fabrics from the point of the comfortable characteristics which are considered to have much meaning in end use. Although the thermal transmittance and moisture and air permeation through a quilt fabric were estimated by the conventional methods, T-HPermeability Tester which was possible to estimate the characteristics in the coexistence condition of heat and moisture was used also.The thermal insulation ratio by the ASTM thermal transmittance test increased with the increases of the number of polyester non-woven fabrics (wadding ) and the spacing between stitched seam lines but the moisture permeation estimated by the cup method had a tendency to change inversely to the thermal insulation ratio. Both the thermal insulation and moisture permeation ratios were equated using the average thickness of quilt fabrics. The airpermeability of quilt fabrics did not always have the same ten-dency toward the moisture permeability. The air permeation wasequated using the packing ratio of quilt fabrics. Unlike thethermal transmittance, the moisture and air permeability was largely effected by the characteristics of outer fabrics. The results obtained by T-H Permeability Tester showed the same tendency toward the results of the conventional methods although there was a large gap. It was considered that T-H Permeability Tester evaluated thermal insulation ratio including the latent heat and it caused the gap. As forthe insulation ratio and the amount of moisture permeation, the results also could be equated using the average thickness. The useful data for designing quilt fabrics were obtained from the results mentioned above.

本研究的目的是从舒适特性的角度获得设计被子面料的基本数据，这些特性被认为在最终使用中具有重要意义。虽然通过传统方法估算被子织物的热透过率、水分和空气渗透率，但还使用了可以估算热和湿气共存条件下的特性的 T-HPermeability Tester。根据 ASTM 的隔热率热透过率测试随聚酯无纺布（棉絮）数量和缝线间距的增加而增加，但杯法测得的透湿率有与隔热性能成反比变化的趋势 比率。隔热率和透湿率均使用被织物的平均厚度来计算。被子织物的透气性与透湿性并不总是具有相同的十倍关系。使用被织物的填充率来计算透气性。与热透过率不同，透湿性和透气性很大程度上受外层织物特性的影响。 T-H渗透率测试仪的结果与传统方法的结果显示出相同的趋势，尽管差距较大。认为T-H渗透率测试仪评估包含潜热的绝热率，并且它导致了间隙。至于保温率和透湿量，也可以用平均厚度来换算。从上述结果中获得了设计被子面料的有用数据。
