Abstract
A papermakers fabric having a system of flat monofilament yarns which are woven with relatively long floats on at least one side of the fabric. In the preferred embodiment, the flat yarns are oriented in the machine direction of the papermakers fabric and are interwoven with at least a top layer of round cross machine direction yarns such that in each repeat, the flat yarns float over more top layer cross machine direction yarns than the number of top layer yarns which the flat yarns weave under. In the preferred embodiment, pairs of vertically stacked flat monofilament yarns are woven in the machine direction such that the upper flat yarns define relatively long floats on the top surface of the fabric and the lower flat yarns define floats on the bottom surface of the fabric.
