ABSTRACT:
A multilayered papermakers' forming fabric comprises at least one set of machine direction (MD) warp yarns, at least a first set of cross-machine direction (CD) machine side layer weft yarns; and paper side layer weft yarns woven in a repeating pattern with at least some of the MD warp yarns. At least some of the paper side layer weft yarns comprise an array of bulk enhancing weft yarns each having a vertical dimension which exceeds a corresponding vertical dimension of each of the remaining paper side layer weft yarns in a ratio of at least 1.25:1. Selected weft yarns can have different float lengths in the paper side surface. The fabrics of the invention impart increased bulk for products such as towel or tissue without loss of other required characteristics.
