Directional electrostatic dissipating fabric and method

摘要

A directional electrostatic dissipating fabric and method of making such fabric constructed of a woven or knitted base fabric having an integrally woven or knitted grid structure which is raised above only one surface of the base fabric forming a fabric with a raised grid on one side and a smooth or substantially smooth grid on the other side thereby resulting in increased, directional electrostatic dissipation performance from the side having the raised grid. The grid is formed from an electroconductive yarn plied to a carrier yarn which is then integrally woven or knitted into the fabric in the warp direction, the fill direction or both, thereby producing a fabric which exhibits the rapid, yet controlled, directional dissipation of static electricity into the air. Such fabric can be used for anti-static covering cloths, filtration media and the like; but is particularly adapted for use in anti-static garments and it is particularly comfortable when the smooth or substantially smooth surface is adjacent the wearer and the raised surface is on the outside of the garment.
