Abstract
A hybrid cut-resistant fabric is a triple weave having non-metallic yarns on a top and bottom face and a metal wire that is integrally co-woven into a derivative weave structure. The top face and the bottom faces are secured to each other by top and bottom interface loops and the metal wire, that extends between the to and bottom faces, is secured to the top and bottom faces by top and bottom wire coupler loops. The metal wires extend in the warp and fill directions to create an integral wire grid that resists cut through. The hybrid cut-resistant fabric is flexible and cut resistant making it suitable for a variety of applications including luggage, apparel and sports equipment, for example.
