CA 2297529

A multiaxial press fabric includes a base fabric and a plurality of layers of staple fiber material attached to the base fabric. The base fabric has at least one layer assembled by spirally winding a woven fabric strip, and takes the form of an endless loop. Because of the spiral winding, the yarns of the woven fabric strip lie in directions different from the machine- and cross-machine directions of the base fabric, giving the base fabric multiaxial characteristics. The woven fabric strip includes, in at least one of its lengthwise and crosswise directions, shaped yarns, which are either hollow yarns or yarns having a non-circular cross section.
