Abstract (en)
[origin: WO9119044A1] A papermakers fabric having a system of flat monofilament machine direction yarns (hereinafter MD yarns) which control the permeability of the fabric. The present weave provides for usage of high aspect ratio yarns as structural weave components. The system of MD yarns comprises upper and lower yarns which are vertically stacked. Preferably, the upper MD yarns define floats on the upper surface of the fabric and each upper MD yarn is paired in a vertically stacked orientation with a lower MD yarn. At least the upper MD yarns are flat monofilament yarns woven contiguous with each other to reduce the permeability of the fabric and to lock in the machine direction alignment of the stacking pairs of MD yarns. The stacked, contiguous woven machine direction system provides stability and permits the MD yarns to have a relatively high aspect ratio, cross-sectional width to height, of greater than 3:1. A seam for the fabric comprised of loops from selected flat MD yarns is provided to render the fabric endless during use in papermaking.
