Abstract
A through-air-drying (TAD) fabric for producing tissue paper and related products on a papermaking machine comprising a plurality of warp yarns interwoven with a plurality of weft yarns to produce a paper-side surface pattern characterized by alternating first pockets and second pockets. The first and second pockets are bounded by raised warp yarns and raised weft yarns produced by knuckles in the fabric pattern. The first pockets are preferably larger in area than the second pockets. The fabric base weave in the interior of the first pocket is preferably a plain weave pattern. The interior of the second pocket may also be bisected by a raised weft yarn.
