Abstract: Thirty different kinds of fabrics commonly used for making leisure wears are selected and their performance indexes such as thickness,weight,bending rigidity,extensibility,shear rigidity,formability,stability etc.before and after lining fusing are acquired by FAST system.Based on these data,factor analysis is carried out with SPSS software,reducing the original variances from 22 to 11 and correlative analysis of the main variances is made.The predictive equation is built by the correlative degree,the linear regression equation is for the closest correlation,cubic regression equation is for the general correlation.Cluster analysis is applied to distinguish the different thickness and weight to illustrate the influence of lining fusing,and it is found that the influence of lining fusing shows the following order: the light and thin fabric,the medium thickness and weight fabric,the thick and heavy fabrics.
