Performance Evaluation of Welded Knitted E-Fabrics for Electrical Resistance Heating

Abstract

This paper presents a study conducted on electrical resistance heating of knitted e-fabric structures including silver plated conductive yarns. The study further investigates the application of ultrasonic welding technology on these knitted e-fabrics in order to see their effect on heating performance. Thermal analysis was carried out under different voltage values to observe temperature variations over the knitted e-fabrics. It was found that the linear resistance of conductive yarns and its interaction with voltage values considerably affect the temperature as well as heating performance of the e-fabrics. In addition, ultrasonic welding parameters also need to be carefully controlled in order to obtain sufficient heating performance.
