Abstract
A woven fabric comprising: a) A first layer of first uncrimped weft filaments; b) a second layer of second uncrimped weft filaments; wherein for each of the first uncrimped weft filaments there is one corresponding second uncrimped weft filament, and vice versa, to form successive filament pairs of first and second uncrimped weft filaments, c) crimped warp filaments having four different weave types c1-c4, but each weave type consisting of entwining around first uncrimped weft filaments; passing between first and second uncrimped weft filaments; entwining around second uncrimped weft filaments; and passing again between first and second uncrimped weft filaments; and d) uncrimped warp filaments passing between the first uncrimped weft filaments and the second uncrimped weft filaments of all filament pairs; wherein the fabric does not comprise crimped warp filaments which entwine around the first uncrimped weft filaments and the second uncrimped weft filaments in alternating manner. This fabric has good resistance to shear delamination and wear-and-tear delamination of an impregnation (11) impregnated into the fabric. Accordingly the fabric can be used in belts intended for applicati…
