Abstract
A triple layer forming fabric includes: a set of top machine direction yarns; a set of top cross machine direction yarns; a set of bottom machine direction yarns; a set of bottom cross machine direction yarns; and stitching yarns interwoven with the top and bottom fabric layers. A pair of first and second stitching yarns is positioned between adjacent pairs of top cross machine direction yarns. The top machine direction yarns, top cross machine direction yarns, and fiber support portions of the stitching yarns interweave to form a plain weave surface. The top machine direction yarns have a first diameter, the bottom machine direction yarns have a second diameter, and the top cross machine direction yarns have a third diameter. The ratio of the first and second diameters is between about 0.75 and 0.95, and the ratio between the first and third diameters is between about 0.8 and 1.1.
