摘要： A multi-layer papermaker's forming fabric of the present invention utilizes stitching yarns in the papermaking surface. The fabric of the present invention is formed of repeating units, each of which comprises: a set of top machine direction yarns; a set of bottom machine direction yarns; a set of bottom cross-machine direction yarns interwoven with the set of bottom machine direction yarns; and pairs of first and second stitching yarns extending in the cross-machine direction. The first and second stitching yarns of each pair are interwoven with the top and bottom machine direction yarns such that, as a fiber support portion of the first stitching yarn is interweaving with the top machine direction yarns, a binding portion of the second stitching yarn is positioned below the top machine direction yarns, and such that as a fiber support portion of the second stitching yarn is interweaving with the top machine direction yarns, a binding portion of the first binding yarn is positioned below the top machine direction yarns. The first and second stitching yarns cross each other as they pass below a transitional top machine direction yarn. Each of the binding portions of the first and second stitching yarns passes below at least one of the bottom machine direction yarns. The fiber support portions of the stitching yarns and the top machine direction yarns form the papermaking surface.

摘要： A multi-layer papermaker's forming fabric has stitching yarns integrated into the papermaking surface. Each of a plurality of repeating units of the fabric comprises: a set of top machine direction yarns; a set of top cross-machine direction yarns interwoven with the top machine direction yarns; a set of bottom machine direction yarns; a set of bottom cross-machine direction yarns interwoven with the bottom machine direction yarns; and pairs of first and second stitching yarns. The stitching yarn pairs are positioned between pairs of top cross-machine direction yarns. The stitching yarns of each pair are interwoven with the top and bottom machine direction yarns such that, as a fiber support portion of the first stitching yarn is interweaving with the top machine direction yarns, a binding portion of the second stitching yarn is positioned below the top machine direction yarns, and such that as a fiber support portion of the second stitching yarn is interweaving with the top machine direction yarns, a binding portion of the first stitching yarn is positioned below the top machine direction yarns. The first and second stitching yarns cross each other as they pass below a transitional top machine direction yarn. Also, each of the binding portions of the first and second stitching yarns passes below at least one of the bottom machine direction yarns. In this configuration, the stitching yarns are completely integrated into the top, or papermaking, surface of the fabric, and therefore do not adversely impact the papermaking qualities of the fabric.

摘要： A warp-stitched multilayer papermaker's fabric has a set of bottom warp yarns, a set of bottom weft yarns, a set of top weft yarns and a set of warp stitching yarn pairs. The bottom warp yarns are interwoven with the bottom weft yarns. The stitching warp yarns interweave with both the bottom weft yarns and the top weft yarns, and are woven such that at locations where the first of the stitching warp yarns in a pair weaves in the top fabric layer, the second stitching warp yarn in the pair drops below the top fabric layer to interweave with one or more bottom weft yarns to bind the top fabric layer and the bottom fabric layer together. The first stitching warp yarn of the stitching warp yarn pair may weave on a first side of one of the bottom warp yarns while the second stitching warp yarn of each stitching yarn pair may weave on the other side of that bottom warp yarn. Each stitching yarn pair may be substantially stacked above a bottom warp yarn. The fabric may further include a set of top warp yarns that interweave with the top weft yarns in the top fabric layer. The set of top warp yarns may be woven from a first warp beam, the set of bottom warp yarns may be woven from a second warp beam and the set of stitching warp yarns may be woven from a third warp beam.

摘要： Triple layer papermaker's forming fabrics having a set of top MD yarns that are interwoven exclusively with a set of top CMD yarns to form at least part of a top fabric layer and a set of bottom MD yarns that are interwoven exclusively with a set of bottom CMD yarns to form at least part of a bottom fabric layer are provided. These fabrics further include a set of stitching MD yarn pairs. The stitching MD yarns that comprise each such pair weave in both the top fabric layer and the bottom fabric layer such that at locations where the first yarn in the pair weaves in the top fabric layer the second yarn in the pair drops down into the bottom fabric layer. In embodiments of the present invention, each stitching MD yarn may also be woven so as to form side-by-side machine direction knuckles on the bottom surface of the bottom fabric layer with a bottom MD yarn. In other embodiments of the invention, at least some of the top CMD yarns that the stitching MD yarns of the stitching MD yarn pairs pass over immediately before dropping down into the bottom fabric layer have a larger diameter and/or a higher modulus than the remainder of the top CMD yarns.
