Modeling of cross-sectional shape for women's jacket design

The shapes of the cross-section can be modeled by the ease distribution of the garment at different altitudes. The girth measurement of a given style as a major factor was used to model the cross-sectional shape for women's jacket in our previous studies, which achieved a reasonable degree of accuracy. However, the simulation can still be enhanced by including additional fabric properties. In order to improve modeling of the cross-sectional shapes for women's jacket with different fabrics, outline and fold of the cross-section were investigated. The jacket girth measurement and fabric bending rigidity were varied to study their effect on the cross-sectional shape. The outline of the cross-section was fitted by the second-order polynomial model with the girth measurement and bending rigidity. The folds of the cross-section were expressed by a function of number and amplitude. The validity of the model was evaluated by experiments with other fabrics. The results showed that the folds of the cross-sectional shapes were well captured by the theoretical model for different fabrics. The predicted outline of the cross-section, which included girth measurement as well as width and thickness, was in reasonable agreement with experimental observation. The model provided valuable information in selecting the fabric for desired appearance of women's jacket.
