Abstract
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.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
125 words
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.
Claim 2
Dependent Claim
125 words
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.
Claim 3
Dependent Claim
16 words
A double layer fabric according to claim 1 wherein the base layer is a nonwoven fabric.
Claim 4
Dependent Claim
16 words
A double layer fabric according to claim 1 wherein the base layer is a woven fabric.
Claim 5
Dependent Claim
16 words
A double layer fabric according to claim 1 wherein the base layer is a knit fabric.
Claim 6
Dependent Claim
28 words
A double layer fabric according to claim 1 wherein the fibers in the base layer are rayon fibers and the fibers in the second layer are rayon fibers.
Claim 7
Dependent Claim
28 words
A double layer fabric according to claim 1 wherein the fibers in the base layer are polyester fibers and the fibers in the second layer are polyester fibers.
Claim 8
Dependent Claim
28 words
A double layer fabric according to claim 1 wherein the fibers in the base layer are cotton fibers and the fibers in the second layer are polyester fibers.
Claim 9
Independent Claim
128 words
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.
Claim 10
Independent Claim
128 words
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.
Claim 11
Dependent Claim
14 words
A method according to claim 8 wherein the base layer is a nonwoven fabric.
Claim 12
Dependent Claim
14 words
A method according to claim 8 wherein the base layer is a woven fabric.
Claim 13
Dependent Claim
14 words
A method according to claim 8 wherein the base layer is a knit fabric.
Claim 14
Dependent Claim
14 words
A method according to claim 8 wherein the second layer is an air-laid isoweb.
Claim 15
Dependent Claim
14 words
A method according to claim 8 wherein the second layer is a carded web.
Claim 16
Dependent Claim
16 words
A method according to claim 8 wherein the spaced streams of liquid are jets of water.
Claim 17
Dependent Claim
27 words
A method according to claim 14 wherein the jets of water are directed against the laminate at a pressure of at least 200 pounds per square inch.
