Abstract
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.
