Abstract
A composite longitudinally balanced electrically conductive yarn has a textile fiber core yarn wrapped with a minimum of two, and a maximum four, filaments. One to four of the filaments are metal filaments with the remainder being synthetic filaments. Each metal filament has an equivalent diameter of between 20 and 80 microns, and a wrap frequency of between 200 and 600 turns per meter. At least one of the metal filaments is wrapped in one direction, and at least one of the remaining filaments is wrapped in the opposite direction. The composite yarns of this invention is capable of elongation to accommodate tensile stresses under use, without experiencing a change in conductivity.
