摘　　要：织物悬垂性是评价织物性能的一个重要指标,它决定了织物是否能形成光滑的曲面从而给人以视觉上的享受。测试了织物在低应力情况下的各项力学性能,包括织物拉伸力、剪切力、弯曲力、摩擦力等相关参数,然后引入了B样条基函数和勒让德基函数,运用函数型主成分分析的方法来分析悬垂形态产生的原因,建立悬垂因子与提取的5个主成分之间的关系方程。Fabric drape is an important index to evaluate the performance of fabric,it determines whether the fabric can form a smooth surface to give a visual enjoyment. We tested the mechanical properties of the fab-ric under low stress,Including the fabric tensile force, shearing force, bending force, friction and other related parameters,then B spline basis function and Le Jean de Ki function are introduced,using the method of function-al principal component analysis to analyze the causes of the formation of drape,the relationship equation between the drape factor and the 5 principal components was established

关 键 词：织物状态 悬垂性 基函数 函数型数据分析 主成分分析
