摘要： A triple layer forming fabric includes: a set of top machine direction yarns; a set of top cross machine direction yarns; a set of bottom machine direction yarns; a set of bottom cross machine direction yarns; and stitching yarns interwoven with the top and bottom fabric layers. A pair of first and second stitching yarns is positioned between adjacent pairs of top cross machine direction yarns. The top machine direction yarns, top cross machine direction yarns, and fiber support portions of the stitching yarns interweave to form a plain weave surface. The top machine direction yarns have a first diameter, the bottom machine direction yarns have a second diameter, and the top cross machine direction yarns have a third diameter. The ratio of the first and second diameters is between about 0.75 and 0.95, and the ratio between the first and third diameters is between about 0.8 and 1.1.

摘要： A papermaker's fabric includes a base fabric structure including machine direction yarns and primary cross machine direction yarns interlacing to form a papermaking surface, wherein the machine direction yarns and primary cross machine direction yarns are interlaced in a pattern having a harness repeat of greater than two. The fabric also includes first and second companion cross machine direction yarns positioned between each pair of adjacent primary cross machine direction yarns. Each first companion cross machine direction yarn has an interlacing pattern relative to the machine direction yarns that is identical to a first of the pair of adjacent primary cross machine direction yarns, and each second companion cross machine direction yarn has an interlacing pattern relative to the machine direction yarns that is identical to a second of the pair of adjacent primary cross machine direction yarns. The first companion cross machine direction yarn is positioned between the second primary and companion cross machine direction yarns. The primary cross machine direction yarns have a first diameter, and the first and second companion yarns have a second diameter, wherein the ratio between the first and second diameters is between about 0.9 and 1.1.

摘要： A triple layer papermaker's fabric includes: a set of top machine direction yarns; a set of top cross machine direction yarns interwoven with the top machine direction yarns to form a top fabric layer; a set of bottom machine direction yarns; a set of bottom machine direction yarns interwoven with the bottom machine direction yarns to form a bottom fabric layer; and a plurality of stitching yarns interwoven with the top and bottom fabric layers. The bottom machine direction yarns and cross machine direction yarns are interwoven in a series of repeat units in which the bottom machine direction yarns pass below two nonadjacent bottom cross machine direction yarns to form bottom machine direction knuckles, and in which pairs of bottom machine direction yarns separated from one another by one or two bottom machine direction yarns form bottom machine direction knuckles under a common bottom cross machine direction yarn. In this configuration, the bottom machine direction knuckles of a pair tend to bow toward one another, effectively lengthening floats present on either side of these knuckles. The increased length offers more bottom CMD yarn contact area to serve as a wear surface. In addition, the presence of these two bottom MD knuckles in close proximity can exert significant force on the common bottom CMD yarn, thereby causing it to crimp substantially. As a result of this crimping force, larger (and, in turn, more wearresistant) bottom CMD yarns can be employed.

摘要： Multi-layer papermaker's fabrics are provided which include in the bottom fabric layer pairs of cross machine direction yarns that are woven in the same shed so as to provide paired bottom fabric layer cross machine direction yarns. Typically, these paired yarns comprise two smaller yarns that replace what otherwise would have been a larger single yarn, thereby reducing the thickness, void volume and water carrying propensity of the fabric. These fabrics may include a relatively large number of cross machine direction yarns on the papermaking surface and/or a papermaking surface having single float machine direction knuckles, so as to provide a high level of fiber support and good papermaking qualities.
