Evaluation of linen plain weave fabrics drapeability

The aim of the paper to test the hypothesis that not only traditional indicators can be used as the criterion for evaluation the fabrics drapeability, but also the coefficient of determination of regression model describing the shape of its surface, because the conformity of the draped fabric shape to the model indicates the regular formation of folds. In addition, it was assessed the effect of stiffness and other characteristics of linen fabric on their drapeability. The object of the research was two articles of unsoftened linen plain weave fabric, as well as samples of these fabrics after the final finishing, carried out using three different technologies. During research 3D scanning of fabric samples was carried out followed by statistical processing of the obtained data, as a result of which the values of the regression coefficients of the model and the coefficient of determination were obtained. Studies have shown that the previously proposed model with a fairly high accuracy describes the shape of the surface of a draped plain weave fabric and the adequacy of the model increases with decreasing stiffness of the fabric.
