Abstract
A wear resistant dual layer papermaking fabric having an upper paper fiber support surface and a lower machine contact surface. The support surface comprises a first plurality of weft yarns interwoven with warp yarns in a balanced twill weave pattern. The machine surface comprises a second plurality of weft yarns interwoven with the warp yarns in a second balanced twill weave pattern. The machine surface includes weft floats which pass beneath at least twelve consecutive of the warp yarns and are bound at opposite ends by binding points in which the weft yarn passes above at least two and below one consecutive of the warp yarns throughout the weave pattern. The weave pattern produces a weft yarn dominated paper support surface having a balanced twill weave pattern of weft floats which provide uniform drainage and minimal paper marking and a weft yarn dominated machine contact surface having a different balanced twill weave pattern of extended weft yarn floats which provides extended wear resistance.
