The development of electro-conductive yarns and the characterization of their conductive properties has gained importance over the past years. However, for their later application, not only the electro-conductive properties of the yarns are important, but also their mechanical characteristics. Hence, this paper presents an analysis of the mechanical behaviour of elastic, electro-conductive hybrid yarns. The yarns comprised an elastic core yarn and electro-conductive winding yarns. Studying the mechanical properties of the hybrid yarns, as well as their corresponding input yarns, it could be proven that the overall good strength and elongation behaviour of the hybrid yarns was depended on the properties of the input yarns, as well as on the yarns’ production parameters.
