Mechanical properties of double-layered woven fabrics used in car seat upholstery

The objective of this study is to examine mechanical performance of double-layered woven fabrics used in car seat upholstery. For this purpose, 450 denier polyester yarns were supplied to produce double-layered woven fabrics. For the production of the fabrics, full weft connection, which is warp yarn of the top layer makes a connection with the weft yarn of the bottom layer, was used. To produce such a fabric, four different factors such as bottom layer pattern, number of interlacing warps in a unit report, number of interlacing picks per top warp and number of weft skips were investigated using Taguchi experimental design. After weaving stage, fabrics were stentered. Mechanical and physical properties of the fabrics were measured before and after stentering and the results were analysed with regard to Taguchi experimental analysis.
