ABSTRACT:
A papermaker's fabric, usable in the forming section of a paper machine, having a top layer and a bottom layer of cross-machine direction (CD) wefts. The top (forming) layer and bottom (wear side) layer are woven together to form a multi-layer fabric. CD packing yarns are inserted between adjacent wear side weft yarns. The packing yarns reduce the void volume on the wear side of the cloth without significantly disrupting the air permeability or increasing the caliper of the fabric. The placement of the packing yarns also adds to the CD stability and seam strength of the fabric and reduces the lateral movement of the wear side weft yarns.
