<p>A forming fabric has a top machine side and a bottom paper side and comprises machine direction yarns and cross-machine direction yarns interwoven in a repeating pattern of multiple repeating units. The repeating units of the pattern comprise preselected numbers of first, second and third yarns. The first yarns being paper side cross-machine direction yarns, at least twice as large in number as the second yarns. The second yarns being machine side cross-machine direction yarns, each positioned below a first yarn. The third yarns being machine direction yarns, each interwoven with both the first and second yarns. The third yarns comprise first and second sets of machine direction yarns arranged in an alternating pattern. The third yarns are interwoven with the first and second yarns in such a way that the desired "zig-zag" configuration on the machine side is retained, but is less prone to twinning.</p> |
