摘要 |
<p>A papermaker's fabric includes a system of machine-direction (MD) yarns interwoven with a system of cross-machine direction (CD) yarns. The MD yarns are pairs of a first MD yarn and a second MD yarn. The first and second MD yarns are of a substantially rectangular cross section having identical width and thickness. The first and second MD yarns of each pair weave side-by-side as a single yarn with the CD yarns through the fabric. The CD yarns are of circular cross section. The fabric has a permeability to air less than 150 cubic feet per minute per square foot at 0.5 inch H2O-pressure. <IMAGE></p> |
