Abstract
A sheet of material suitable for roofing or industrial wrapping applications has an anti-skid surface formed by ridges of twisted tapes. The sheet comprises a woven scrim of warp tapes and weft tapes. Some of the tapes are twisted about their longitudinal axis, for example about (25) to (400) revolutions per meter, to form ridges having a height substantially greater than the thickness of the tapes. The ridges impart an anti-skid surface to the sheet. The scrim is bonded to a coating or film to make the sheet waterproof.
