Abstract
A multi-layer woven scrim, having two or more layers made of thermoplastic tapes, has its layers attached together by means of layer-connecting tapes interwoven with mutually perpendicular tapes of adjacent layers. The points of attachment may be at spaced intervals and in the machine or cross-machine directions. The scrim is flexible, dimensionally stable and has high tensile and tear strength. It can be coated and used as an industrial fabric.
