The purpose of a lining is to provide the comfort of the wearer, preserve the shape of a garment, conceal construction details and raw edges of fabric, thus giving a neat appearance to the inside of the garment. In this study, it was aimed to research the sewability properties of main lining fabrics by using the L&M Sevrability Tester. Six types of linings were used and they were grouped according to their warp and weft densities, yam count and fabric composition. Three groups were generated by considering variations of the warp density, weft density or yam count, while the other parameters were constant. At the end of the study, it has seen that, yarn count and density have a direct influence on the sewability values of lining fabrics. Also it was observed that sewing needle penetration force of lining fabrics were affected by the fabric density in both directions and yarn count.
