Abstract
A double layer, nonapertured textile fabric comprising two integrally entangled layers. The first layer contains fibers arranged to form a pattern of apertures or openings in the layer. The second layer comprises a plurality of entangled areas which are disposed within the apertures of the first layer to form a unitary textile fabric.
Claims15
a double layer fabric consisting essentially of a base layer and a second layer substantially coplanar and integrally entangled with said base layer, said base layer consisting essentially of a plurality of fibers arranged in a pattern of yarn-like bundles which define a pattern of apertures in said base layer, said second layer consisting essentially of a plurality of highly entangled fiber areas, wherein said highly entangled fiber areas are arranged in a complementary pattern to the pattern of the base layer, wherein said fiber areas are disposed in the apertures of said base layer whereby the double layer fabric is nonapertured, and wherein portions of said fibers of said entangled fiber areas are wrapped and entangled with portions of fibers of said base layer.
A method of manufacturing a nonapertured textile fabric comprising placing a base layer and a second layer on a foraminous support member, said base layer containing a pattern of openings and a pattern of yarn-like fiber bundles, said second layer comprising a web of overlapping, intersecting fibers, said second layer being placed on top of said base layer, said foraminous support member having from 1600 to 90,000 openings per square inch and from 30 to 70 percent open area, treating said laminate while supported on said foraminous support member with longitudinally and transversely spaced streams of liquid to rearrange said fibers in said layer into highly entangled fiber regions disposed within the openings in the base layer while leaving the fiber configuration in the base layer relatively unchanged.
