Abstract:
1. A multi-axial papermaking fabric having a paper side (PS) surface and a machine side (MS) surface, the fabric comprising: a base fabric formed from a woven and spirally wound precursor textile strip having a width that is less than an overall width of the assembled press felt and which is joined together along neighboring longitudinal edges to form a fabric tube; the precursor textile strip comprising a plurality of generally linearly extending vertically stacked pairs of machine direction (MD) warp yarns interwoven with a system of cross-machine direction (CD) weft yarns in a repeat pattern which maintains a vertically stacked alignment of the pairs of MD warp yarns such that 50% of the pairs of MD warp yarns are located on a first surface of the strip, and a remaining 50% of the pairs of MD warp yarns are located on a second surface of the precursor textile strip; the precursor textile strip further including both polymeric single monofilament and cabled yarns; wherein the cabled yarns comprise at least two monofilaments cabled together and the cabled yarns comprise at least 50% of at least one of the CD or MD yarn systems, the cabled yarns are comprised of cabled polymeric yarns selected from: monofilaments, bi-component yarns or hollow yarns, and the cabled yarns consist of two pairs of twisted polymeric yarns which are twisted together.
