Abstract:

Stretch woven fabrics are widely used because of their good elongation and recovery (residual extension) properties. Several parameters and test method are used to measure the properties of these fabrics. Each different set of test parameters means a different test application. Sometimes, repeating tests for different test involves wasting time and labour. In this study, the test results were used to try and predict elongation and recovery using neural network and linear regression models. Certain test parameters such as rate of extension, gauge length (jaw separation), and maximum load were selected as input variables. The accuracies of predictions of elongation in the direction of warp and weft by both models were found to be similar and satisfactory. The predictions for the recovery test showed differences as to fabric warp and weft direction. All the statistical results indicate that predicting the fabrics’ test results from an unseen data set is very good for both models.
