Investigation of the techniques decreasing the seam slippage in chenille fabrics (Part I)

Seam slippage, which occurs frequently in furniture upholstery fabrics on the parallel sewing line, even though it is undesirable, results in partial or full distortion of fabric appearance. The purpose of this study is to reduce the seam slippage in upholstery chenille fabrics, which are widely used in furniture production. This is the preliminary study, in which the effects of sewing direction and the number of interlaced chenille yarns over warp yarns on seam slippage were investigated for the first time. Aside from the effects of fiber content, sewing stitch step, weft densities of fabrics, sewing direction according to the weft and warp and the number of interlaced chenille yarns over warp yarns on seam slippage were studied with the use of multifactor experiment. On the basis of these experiments, effects and impact factors of the aforementioned parameters on seam slippage were shown with the use of mathematical models.
