Patent abstract

A forming fabric having a paper side layer and a machine side layer comprises a first set of paper side layer wefts, a second set of machine side layer wefts and a single set of warp yarn triplets. In 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 unbroken warp path in the paper side surface, and each triplet in each set of warp yarns interlaces alone with at least one single machine side layer weft yarn. Each segment in the unbroken warp path is separated by at least one paper side layer weft yarn. The machine side layer interlacing points are regularly spaced. After heat setting, the fabrics typically have an air permeability typically from about 7,500 to about 10,500 m3/m2/hr. Paper products made using these fabrics have enhanced printability.
