ABSTRACT:
A loosely constructed knit or woven fabric is dimensionally stabilized by causing staple length textile fibers to be entangled about the intersections of the yarns comprising the fabric. The stabilized fabric is formed by covering one or both sides of the loosely constructed base fabric with a light web of the staple length fibers, and subjecting the composite material to hydraulic entanglement while supported on a porous forming belt configured to direct and concentrate the staple length fibers at the intersections of the yarns comprising the base fabric.
