摘　　要：膨松性能是变形纱最基本的性能之一，可用膨松度表征。纱线的膨松度是以纱线空隙率即纱线体内部纤维间的空隙占纱线整体的体积分数定义的。实验证明：用EIB检测各类纱线的表观平均直径并计算膨松度有良好的适应性；空气变形纱的膨松度阈值在70％～75％之间；异收缩-空气变形纱的膨松性好于空气变形纱，其膨松度约高出5％；2种环锭纺短纤维纱，精梳棉纱和精纺毛纱的膨松度阈值为55％～60％，其中精纺毛纱比精梳棉纱高5％；加捻化学纤维长丝束的膨松度为20％～25％，经变形加工后其膨松度可以提高2倍左右。As one of important properties of the textured yarns, the bulkiness was defined as the percentage of the inner space to the whole. It was proved that EIB can do well in testing bulkiness. The bulkiness of air-jet textured yarn could be 70% -75%; and for differential shrinkage and air-jet muhi-textured yarn, it is about 5 % higher than that of air-jet textured yarn; for combed cotton yarn and worsted yarn, the bulkiness ranges 55% - 60%, where the worsted yarn＇s was about 5% higher than that of combed cotton yarn＇s; the bulkiness of twisted filaments was 20 % - 30 %, of which the value can be increased 2 times when it is textured.
