At lea st 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 lengt hs in the paper side surface.
