Abstract
Multi-layer papermaker's fabrics are provided which include flattened bottom fabric cross machine direction yarns that advantageously reduce the void volume and water carry of the fabric. These flattened yarns may be of oval, rectangular or other shape. These fabrics preferably 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. The fabrics also preferably include good drainage paths between the flattened bottom cross machine direction yarns.
