Abstract
A multi-ply forming fabric is provided for use at the wet end of a paper-making machine for receiving wet pulp 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 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 than conventional fabrics.
