<p>A flat woven, pin seamed, papermakers' fabric, comprising primary warp monofilament yarns (1-4), primary weft monofilament yarns (11-14) and secondary weft monofilament yarns (21-24) located between and adjacent to the primary weft yarns (11-14). The secondary weft yarns (21-24) are located beneath, and in contact with, the primary warp (1-4). The thickness and width of the secondary weft yarns (21-24) are chosen at the weaving stage so as to control finished fabric air permeability and increase the paper side surface contact area. The fabrics are of a lower caliper, and provide increased cross direction stiffness at lower yarn counts. Formation of the pintle receiving loop (P) yarns in a low marking woven back pin seam, or of a streamline seam, is also facilitated, without compromising fabric properties, by selection of the appropriate dimensions of the secondary weft yarns (21-24). The fabrics are woven using either round or flattened primary warp yarns (1-4), and either round or flattened monofilament primary weft yarns (11-14), or a combination thereof, according to any weave pattern which provides for floats of the primary warp yarns (1-4) that extend over two or more adjacent primary weft (11-14). <IMAGE></p> |
