Claim:
A warp-stitched triple layer papermaker's fabric having a top fabric layer that has a papermaking surface and a bottom fabric layer that has a machine side surface comprising: a set of top warp yarns woven from a first warp beam that weave exclusively in the top fabric layer; a set of top weft yarns interwoven with the top warp yarns; a set of bottom warp yarns woven from a second warp beam that weave exclusively in the bottom fabric layer; a set of bottom weft yarns interwoven with the bottom warp yarns; a set of stitching warp yarns woven from a third warp beam that interweave with at least some of the top weft yarns and with at least some of the bottom weft yarns to bind the top fabric layer and the bottom fabric layer together; wherein the stitching warp yarns are woven as stitching warp yarn pairs such that at locations in the fabric where the first of the two stitching warp yarns in the stitching warp yarn pair weaves in the top fabric layer, the second of the two stitching warp yarns in the stitching warp yarn pair drops below the top fabric layer so that together the two stitching warp yarns in each stitching warp yarn pair complete the weave in the top fabric layer; and wherein, in each repeat of the fabric, each stitching warp yarn and a respective one of the bottom warp yarns that is directly adjacent to said stitching warp yarn pass below the same bottom weft yarn.
