摘　　要：选用12种不同原料组分、不同面密度的蚕丝、羽绒单层絮片以及6种不同的蚕丝/羽绒组合絮片,测试分析了18种絮片的厚度、蓬松度以及保暖性。结果表明:同一面密度下,鹅绒絮片保暖性能优于鸭绒絮片,桑蚕丝絮片和柞蚕丝絮片保暖性能差异不明显;同一组合比例下,桑蚕丝+鹅绒+桑蚕丝絮片的保暖性能优于柞蚕丝+鸭绒+柞蚕丝絮片。将实测的多层絮片热阻与组成该多层絮片的单层絮片热阻进行理论叠加计算后对比发现:单层絮片叠加热阻高于多层絮片热阻。综合而言,与蚕丝、羽绒单层絮片相比,组合絮片兼具蚕丝的贴合性与羽绒的保暖性,通过改变填充配比可在不同场景下使用,是一种更优的保暖絮片材料。Twelve types of silk and down single-layer wadding with different raw material components and different gram weights,as well as six different silk/down combined wadding are used to test and analyze the thickness,fluffiness and thermal resistance of these 18 waddings.The results showed that under the same surface density,the thermal resistance of goose down wadding is better than that of duck down wadding,and there is no significant difference in thermal insulation performance between mulberry silk wadding and crushed silk wadding;under the same combination ratio,the thermal resistance of mulberry silk+goose down+mulberry silk wadding is better than that of crushed silk+duck down+crushed silk wadding.After theoretical superposition calculation of the measured thermal resistance of the multi-layer waddings and the thermal resistance of the single-layer waddings that make up the multi-layer waddings,it is found that the superposition thermal resistance of single-layer wadding is higher than that of multi-layer wadding.Compared with the silk and down single-layer wadding,the combined wadding have the fitness of silk and the warmth retention of down,and can be used in different scenarios by changing the filling ratio,which is a better material for warming wadding.
