Abstract
A multi-ply forming fabric for use at the wet end of a papermaking machine for receiving wet pup having a substantial portion of recycled paper fibers. The forming fabric cannot be characterized as either a conventional double-layer or triple-layer fabric. The fabric has an independent top ply comprising a self-sustaining weave of warp yarns and shute yarns, and a bottom side comprising a series of dependent shute yarns interwoven with the top ply by binder warp yarns. The binder warp yarns are illustrated as single and double round yarns, and single ovate yarns. The fabric has a reduced caliper, larger internal fiber interstices and substantial projected open areas which trap fewer contaminants and allow the fabric to be more easily cleaned.
