As mentioned earlier, it's referred to as 'scrim' in the theatrical AND upholstery trade...A very fine mesh of a fabric(sort of gauze-y, but not quite), usually black, which, under the proper lighting conditions, hides all that is behind it...You may find some fixed to the underside of your chairs and sofas where it is used as a dust-block...
