Abstract

See full text

A machine knittable hybrid yarn for providing conductive traces through a textile is disclosed. The hybrid yarn includes conductive wires coated with an insulating material and twisted together with a nonconductive yarn. The nonconductive yarn is from a strong, inelastic, and nonconductive fiber, such as a meta-aramid or para-aramid that protects the integrity of the conductive wire during knitting. The conductive wire can be copper-clad stainless steel or copper wire is coated with polyurethane, and the nonconductive yarn can have no-drip and no-drip properties to allow ablation of the hybrid yarn to remove the conductive yarn and insulating coating on the wire such that the ablated region becomes externally conductive and suitable for making an electrical contact. The hybrid yarn can be bonded with nylon or similar polymer after twisting.
