Abstract
A papermaker's fabric includes: a set of top MD yarns; a set of bottom MD yarns; a set of top CMD yarns interwoven with the top MD yarns to form a top fabric layer; a set of bottom CMD yarns interwoven with the bottom MD yarns to form a bottom fabric layer; and a set of stitching yarns that interweave with the top and bottom fabric layers. The top MD yarns and the top CMD yarns are interwoven in a series of repeat units and the bottom MD yarns and the bottom CMD yarns are interwoven in a series of corresponding repeat units. Each of the bottom MD yarns forms a bottom MD float by passing under three or more consecutive bottom CMD yarns.
