<p>A forming fabric having a paper side layer and a machine side layer comprise s at least two systems of weft yarns and a single set of warp yarn triplets. I n the fabric weave pattern, each member of each triplet set of warp yarns interweaves with the paper side weft yarns to occupy in sequence segments of an unroken warp path in the paper side surface, and the members of each triplet interlace in pairs with single machine side layer weft yarns. Each segment in the unbroken warp path is separated by at least one paper side layer weft yarn. The machine side layer interlacing points can be regularly or irregularly spaced. After heat setting, the fabrics typically have a warp fi ll from boutt 105 % to about 140 %, an open area of at least 35 % in the paper side surface, and an air permeability typically from about 3,500 to about 8,200 m3/m2/hr. Paper products made using these fabrics have enhanced printability.</p> |
