Analytic Study Regarding Yarn Geometry of Two Synthetic Materials Used in Furniture and Automotive Industry

Abstract:

In this study the knitted fabric side of two leather substitute materials was analysed. The two synthetic leather material used are usually fabricated for the use as upholstery in the furniture and automotive industry. The first material has a polyurethane (PU) matrix and the second has a polyvininylchloride (PVC) matrix.The main analysis done in this study was the geometrical calculus of the yarn eye using different geometric models and the evaluation of the relative deformation in surface for a biaxial tensile loading (along the rows and the columns of the knitted fabric). Results show a relative deformation of 6.29% for the PU matrix material and a 9.41% relative deformation for the PVC matrix material.The main goal of this study was to obtain a better characterization of the materials studied in order to have indications based on loading conditions when using these materials in their different industrial application.
