Analysis of fabric defect
Air-jet texturing is a well-established filament yarn processing technology that has been around for more than half a century. This project analyzed a serious warp streak problem in a woven fabric produced for car seats composed of 100 % Polyester air textured yarn. Yarn variability regarding stress-strain properties, force elongation relation, yarn diameter variations, thermal shrinkage and the structural behavior of two samples of yarn is being investigated. One of the yarn samples was producing these defects in the fabric and the other not producing this defect. Moreover the comparison of the influence of these parameters on both the samples is also being monitored. Variation in the behavior of these samples is observed.
