Abstract
A papermaker's fabric includes a series of repeat units. Each of the repeat units includes: a set of top machine direction (MD) yarns; a set of top cross-machine direction (CMD) yarns interwoven with the top MD yarns to form a top fabric layer; a set of bottom MD yarns; and a set of bottom CMD yarns interwoven with the bottom MD yarns to form a bottom fabric layer. Each bottom MD yarn passes over a top CMD yarn that its immediate neighboring top MD yarn passes under. The top MD yarns, the top CMD yarns, and the bottom MD yarns interweave to form a twill papermaking surface on the top fabric layer.
