Abstract:

To evaluate the accuracy of the fabric model used in virtual cloth, it is necessary to compare the bending properties between the virtual fabric and real fabric. A new method is proposed to test the bending property of woven based on image processing. An instrument has been made to collect the bending shape of woven fabrics under the cantilever beam tests. The real fabric bending under its own weight consists of warping which is inevitable in most cases. Therefore certain curve a mid-curve selected from five candidates has been proved to be the suitable bending curve to represent the bending shape of the fabric. An approach of the mid-line representing the fabric’s bending properties has been developed after calculating the bending stiffness of fabric’s five different curve. This calculation and test method have been validated by experimental observations and correlation with KES test method.The results of tests on 45 degree and 41.5 degree inclined plane also reached a good consistency.
