The clothes are deformed differently by wearer. Parts of the clothes that are affected by repetitive forces, such as sleeves on the elbow or pants in the knee, show this deformation more. This is a three-dimensional deformation of fabric; that is called bagging. This phenomenon is a kind of deformation that is considered to be both elastic deformation and pelastic deformation. Considering that the bagging creates a spatial deformation in fabric, it is difficult to analyze this phenomenon. Various methods have been proposed to study this phenomenon that the most of these methods are observing the amount of deformation created in the textile and its qualitative analysis. There are also new developed methods for further review. However, further investigation needs for better bagging analysis. In this research, we have tried to analyze a new method based on the use of conductive yarns on fabric to analyze bagging. The conductive thread is sewn on different parts of the fabric and is subjected to a force similar to that applied by the body. The stretch applied to the fabric makes the stitching on the conductive thread sewn, which causes a change in the conductive thread resistance. By analyzing data on the change the resistance of the samples, bagging can be analyzed. For better investigation, different conductive yarns or variations in existing parameters can be studied. According to studies, the use of threaded 40% steel and 18 SPI sewing densities had the best results.
