摘　　要：充气保暖功能服装是以空气代替羽绒等填充材料的一类保暖服装。为更好地掌握充气量、充气复合面料厚度与热阻的关系,在5种充气状态(0%、30%、50%、70%、100%)下,测试了12种不同充气复合面料的厚度与热阻的变化。通过对测试数据的整理与分析,建立了三者之间的关系模型。实验结果表明:充气量、充气复合面料厚度与热阻三者之间存在较强的正相关关系;充气量越多,充气复合面料厚度越大,当充气量较少时,充气复合面料之间的厚度差异性较小,充气量越多时其差异性越显著;充气复合面料热阻随充气量的增加呈现先显著升高后趋于平稳的趋势,当充气量达到50%左右时热阻逐步趋于稳定;充气复合面料厚度越大,充气复合面料热阻越大,且当其厚度在20 mm左右时热阻趋于平稳,可作为保暖厚度的参考依据。实验证实充气复合面料在一定程度上具有调温保暖功能,参照所建模型通过调整充气量可以达到不同的保暖效果。Objective Inflatable clothing is a type of warm keeping clothing that replaces down with air because the thermal conductivity of stationary air is the smallest,and inflatable clothing is constantly developed and designed using this principle.However,there is currently less research on inflatable fabrics,and it is necessary to explore the relationship between the thickness of the air gap inside the fabric and the thermal resistance.Therefore,the purpose of this study is to grasp the relationship among inflation volume,the thickness of air layer and the thermal resistance,and to establish relevant models to provide theoretical reference and application value for enterprises and researchers.Method This research selected 12 different types of commercial inflatable fabrics,and evaluated the thermal resistance of these inflation fabrics with 5 different inflation volumes of 0%,30%,50%,70% and 100%.Statistics analysis of experimental results was performed through single-factor analysis,correlation analysis,fitting regression analysis and other methods to understand the relationship among the three.Results The experimental results show that the greater the inflation volumes,the greater the thickness of the air gap,and the more linear distribution of the two.The regression equation was obtained(Fig.5).When the inflation volume was small,the difference in the air gap thickness between the fabrics was small,and the greater the inflation volume led to the more significant difference in the air gap thickness,and this was true for different fabrics(Fig.3).The thermal resistance of the aerated fabric increased with the increase of the inflation volume(Fig.4),and the thermal resistance was affected by the performance of the fabric itself.There were significant differences in different inflation states.As an example to illustrate,fabric 10^(#)was thicker and the thermal resistance was larger.Overall,the thermal resistance of the aerated fabric rose and then stabilized with the increase of the inflation volumes,and a Logistic mode
