Hybrid Cover Yarn’s Element Orientation and Its Impacts on Mechanical/Tensile Behavior of Conductive Yarns and Fabrics

Conference paper


Of the different techniques to produce conductive yarns for e-textiles, multicomponent hybrid yarns with continuous metallic filaments are well known for its ease in processability, better durability, and conductivity. Continuous metallic wires in yarn’s core have been researched vigorously, but since the metal wires are stiff, they produce fabrics with open interstices and make the fabric transparent towards higher-frequency electromagnetic waves. Moreover, this problem further elevates with an attempt to increase the amount of metallic content to improve the electromagnetic shielding capabilities. Continuous metallic filament, wound as spiral covers on textile core in form of hybrid cover yarns, is proven to have better control of the metallic component via altering the turns per meter of the coverings, which also improves the electromagnetic shielding capabilities of the ultimate fabrics. However, the consequence of this alternate orientation on the tensile and mechanical properties of the fabrics has never been studied. This study analyzes the mechanical properties of copper-covered polyester yarns. This orientation of hybrid cover yarns is far much superior in terms of the yarn’s tensile properties with around fourfold increase in the tenacity values and around 30–70% reduction in modulus values. The fabrics prepared from the copper-covered yarn design required around 50–200% more force at around 200% more elongation to rupture, as compared to the conventional fabric design. Moreover, the fabric stiffness and abrasion properties in the copper-covered orientation also improve, but at the cost of increased static friction of the fabrics.
