ABSTRACT:
A method of making a multi-layer non-woven multiple biased fabric is disclosed. A layer of fabric is directed in a longitudinal direction of travel, wherein the layer of fabric is comprised of a plurality of structural fibers oriented substantially parallel to each other and oriented at an angle to the longitudinal center line of the fabric. The layer of fabric may or may not be previously biased. If not previously biased, then the structural yarns of the fabric are biased in a biasing stage to form a layer of single bias structural fabric having the structural fibers biased to the fabric centerline. The single biased fabric layer is led into at least one folding stage for folding the biased layer longitudinally from one edge toward another to form a multiple biased fabric. The multiple biased fabric is led from the at least one folding stage into an affixing stage for affixing the multiple biased fabric together to provide a single structural fabric being multiple biased.
