Abstract
A multilayer, woven fabric for use in a papermaking machine includes a self-sustaining top layer including a plurality of top machine direction yarns interwoven with a plurality of top cross-machine-direction yarns and a bottom layer including a plurality of bottom pairs of machine direction yarns interwoven with a plurality of bottom cross-machine-direction yarns. Each of the bottom cross-machine-direction yarns substantially vertically underlies a respective top cross-machine-direction yarn and each of the bottom pairs of machine direction yarns substantially vertically underlies a respective top machine direction yarn, with at least one of the machine direction yarns in at least some of the bottom pairs of machine direction yarns interweaving the bottom cross-machine-direction yarns to each other and to the top cross-machine-direction yarns of the top layer.
