The seam slippage in woven fabric products is an adverse event in sewn products. The purpose of this study is to examine the seam slippage in chenille fabric products which are widely used as upholstery fabrics and to research ways to decrease seam slippage. In this study, the theoretical analysis of the seam slippage mechanism has been performed by the literature analysis and the results of experimental studies which were obtained in Part I. In this analysis, seam slippage is examined as the sum of two factors: the deformation of sewing stitch and the slippage of the fabric yarns by sewing stitch chains. According to the theoretical analysis of the processes, it can be inferred that it is possible to decrease seam slippage by driving the energy of applied mechanical forces to other tasks. Based on the results, the ways to decrease seam slippage, which occur in sewn products, have been determined. Two of them are related to the selection of sewing yarn and sewing parameters based on previous researches. The dependence of the other two ways on the fabric structure supported with adhesive interlining and the selection of sewing type were examined. The results of the experimental studies supported the results of the theoretical analysis.
