Relationship between index of performance and drape shape of polyester fabric

In order to predict the fabric drape shape using the index of its mechanical properties,the mechanical and basic structure parameters of fabrics were obtained through a great deal of experiments.Multiple linear regression analysis was used and a series of predictive equations for draping property were figured out.The results were verified by computer simulation.The research showed that fabric drape shape are closely related to the mechanical and basic structure parameters,especially the shear rigidity in the direction of 45°,interweave resistance,thickness and weft density,their differences will cause tremendous changes in appearance of fabric drape and influence drape aesthetic feeling.Computer simulation demonstrated that the predicted drape shape is in good agreement with that of the original sample.
