Method and apparatus for making conductive yarn

摘要

A conductive yarn includes a continuous non-conductive carrier thread having a relatively low modulus of elasticity; a continuous metal thread; and the carrier thread being wrapped around the metal thread. A process for making such conductive yarn includes the steps of pulling the continuous metal thread off a first package; pulling the continuous carrier thread off a second package; applying a relatively high tension to the carrier thread with respect to the tension on the metal thread as both threads are being pulled off their respective packages; and wrapping the tensioned carrier thread around the pulled metal thread. Apparatus for performing the method is also provided.
