Multivariate analysis of curve parameters to predict fabric stiffness handle from a pulling-out test:

The Comprehensive Handle Evaluation System for Fabrics and Yarns (CHES-FY) is capable of measuring multiple physical and mechanical properties of fabrics, which are related to fabric handle. In this study, ten curve parameters were defined from the pulling-out force–displacement curve of the CHES-FY. Factor analysis was used to remove the co linearity of the curve parameters in order to better characterize the stiffness handle of fabrics. Three principal factors were established using the factor analysis, and the first principal factor was termed the stiffness index based on loadings of the curve parameters to the rotated factors. Comparisons between the evaluation results of the CHES-FY, cantilever test, and newly-developed dual subjective/objective assessments showed that the CHES-FY, together with the stiffness index resulting from the factor analysis, provided a fast and effective method to characterize a fabric’s stiffness handle, and the evaluation process of the CHES-FY appears to closely simulate ...
