Abstract
The present invention relates generally to papermaking, and relates more specifically to fabrics employed in making press felts on a paper machine, pulp machine fiber cement belts, and corrugated paper board, or box-board. The invention also relates to the monofilament base of fabric optionally with a needled batt which can provide one or more of the following advantages: hydrolysis resistant materials, providing light weight high strength fabrics, having a high permeability, and soft surface with a high coefficient of friction. The present invention also relates to an integrated loop seam integrated with machine direction yarns of the monofilament base which can provide one or more of the following advantages: extremely stable and flexible corrugator fabric, and the ability to provide a non-marking loop seam.
