Abstract
In this research, polyurethane (PU) and polyurethane/silicone (PU/silicone) coated fabrics were manufactured and the effects of coating parameters such as coating material, coating technique, and production parameters on sewing performance of the coated fabrics were investigated. During manufacturing processes, one fabric sample having cotton as raw material and having plain weave was used as the base fabric. The base fabric was coated with two coating materials as PU and PU/silicone by two coating techniques such as rotary screen coating and blade coating with systematically changing production parameters (screen pressure and contact angle). Therefore, twelve coated fabric samples having different technical specifications were produced. Due to the limited number of studies in related literature, sewing performance of the coated fabrics was investigated by the tensile properties of the unsewn and the sewn fabrics and also the seam efficiency values were compared. Variance analyses were used to determine and evaluate the effects of coating parameters on seam performance of the coated fabrics.
