Abstract
A sheet of material with an anti-skid surface, suitable for use as a roofing underlayment or wrapper, comprises a scrim made of woven plastic tapes with monofilaments that are round in cross-section and have a diameter larger than the thickness of the plastic tapes interwoven with the tapes. The monofilaments form ridges on the sheet material that impart an enhanced coefficient of friction to it. The monofilaments may be incorporated in the weave in the warp or weft directions or both.

A sheet of material having an anti-skid surface, comprising:
- a first set of tapes generally parallel to each other;
- a second set of tapes generally parallel to each other and perpendicular to the first set of tapes;
- the tapes being extruded plastic and having a width greater than their thickness;
- the tapes of the first set and of the second set being interwoven with each other to form a scrim;
- a first set of filaments generally parallel to the first set of tapes, each filament of the first set being positioned on a respective tape of the first set of tapes and following a weaving path the same as said respective tape of the first set of tapes, each said filament of the first set of filaments being interwoven with the tapes of the second set, the first set of filaments being exposed on only a first side of the sheet of material;
- the filaments of the first set of filaments being generally round in cross-section and having a diameter at least six times greater than the thickness of the respective first and second tapes and forming ridges on the first side of the sheet that provide the anti-skid surface.
