摘　　要：应用SPSS统计软件,对缝纫线的断裂强力、韧度指数等16项物理机械性能指标进行因子分析,按特征根大于1和因子累计贡献率大于80%-85%选出前3个因子。利用这3个因子值对缝纫线进行聚类分析,将其聚为4类,类群Ⅰ和类群Ⅱ的综合物理机械性能较好,类群Ⅲ的综合物理机械性能中等,类群Ⅳ的综合物理机械性能较差。同时,运用因子回归分析法,建立了线迹质量的评价指标即缝缩率、缝迹强度、缝迹延伸度与3个因子之间的回归数学模型,可用于预测缝纫线的线迹质量。The factor analysis of 16 physical property indexes such as breaking strength, breaking toughness of sewing threads was undertaken using the statistical products and service solutions（SPSS software）. Three factors were chosen according to the criteria of eigenvalues 〉 1 and factors cumulative contribution root 〉 80 % - 85 %. Then four clusters were obtained by cluster analyzing of the three factors. The comprehensive physical properties of cluster Ⅰ and Ⅱare fairly good, cluster Ⅲ is moderate, and cluster Ⅳis relatively poor. At the same time, by means of regression analysis on factors, regression models of the relationship between evaluation indexes of seam quality which includes seam cockling, seam breaking strength, seam breaking elongation and the three factors were established, which could be used for estimating the seam quality of sewing threads.
