ABSTRACT:
Cut-resistant yarn suitable for machine knitting and machine-knitted protective articles of apparel, more specifically flexible gloves, at least in part made from such a yarn and also such gloves having a slip-resistant coating, preferably polyurethane, applied in a predetermined pattern to the outside surface of the gloves. The yarn utilizes a core of synthetic fibers held in a bundle by two initial wraps of low denier synthetic material having widely spaced turns or by a plastic coating on, or by a plastic matrix for, the fibers. One or more strands of metal wire or glass fiber are disposed about the core. The initial wraps or plastic that bundle the core create a uniform, cylindrical shape to the multi-filament fiber core that is believed to increase cut-resistance and that promotes uniformity in yarn diameter as subsequent wraps are applied, and prevent sharp bends in the wire or glass fibers disposed about the core. Additional wraps cover the wire or glass fiber.
