The textile industry is actively seeking advanced materials that offer unique functionalities, particularly in the realm of storing and transmitting electrical energy. These capabilities rely on the use of conductive yarn materials. To facilitate a seamless knitting process without causing abrasion to the knitting tools or the conductive layer, it is essential to enhance these yarns with additional application-specific adaptable functional layers. This enhancement can be achieved through both traditional and innovative yarn coating processes. Notably, the functional layer contributes to minimizing friction, a crucial factor for reducing abrasion during processing. In support of fundamental investigations, a dedicated test rig has been developed within the project to simulate the movements between needles and yarn during the knitting process.
