摘　　要：为了探究厚度对空气层、纤维絮片组合试样保暖性能的影响,运用平板法进行试验,测试了空气层试样、超卷曲聚酯絮片组合试样、牦牛绒絮片组合试样在不同厚度下的热阻和导热系数。结论证实:随着厚度增加,空气层热阻先增加后趋于平稳,导热系数显著增加;纤维絮片热阻增加显著,导热系数增加不明显;厚度小于1 mm的空气层保暖效果较好,最适宜制作充气式保暖服装。In order to explore the influence of different thicknesses on the heat preservation performance of the air layer and fiber flake composite samples, the flat plate method is used to test the thermal resistance and thermal conductivity of air layer, super-curled polyester flakes, and yak flock composite samples under different thicknesses. It is found that with the increase of the thickness, the thermal resistance of the air layer increases first and then tends to be stable, and the thermal conductivity increases significantly;The thermal resistance of the fiber flakes increases significantly, but the thermal conductivity does not increase significantly;The air layer with a thickness of less than 1 mm has better thermal insulation effect, and is most suitable for making inflatable thermal clothing.
