摘　　要：膨松性能是变形纱线最基本的性能，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百分比定义的．实验证明，用Electronic Inspection Board（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；各类纱线样品膨松度分布于20％～70％之间，以异收缩-空气变形纱和空气变形纱的膨松性最好，以后顺次为毛纱、棉纱、化纤长丝纱．As an important property of the textured yarns, the bulk is defined as the percentage of the inner space to the whole. It is improved that electronic inspection board（EIB） can do well in testing bulk. Generally, all the samples＇ bulk fall in 20%- 70%, of which the air-jet textured yarn and differential shrinkage and air-jet multi-textured yarn own the biggest one, and following them, there are worsted yarn, combed cotton yarn, the twisted multifilament in turn.
