Abstract
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.
