A three-dimensionally imaged nonwoven fabric, as formed in accordance with the principles of the present invention, contemplates a material formed by hydroentanglement of at least one lightly bonded continuous filament layer upon a device having a three-dimensional foraminous forming surface. The preferred continuous filament substrate is in the form of a precursor web comprising spunbond continuous polymeric filaments. A nonwoven fabric formed in accordance with the present invention may be formed to include substantially continuous filaments (from a relatively lightly bonded spunbond precursor web), with the resulting fabric having a machine direction tensile strength of at least about 1,472 grams per centimeter at 47% machine-direction elongation.
A nonwoven fabric, comprised of a plurality of essentially continuous thermoplastic filaments, said thermoplastic filaments imparted with a three-dimensional image by impingement of fluid streams, said three-dimensional image imparting apertures to said imaged, continuous filament nonwoven fabric, said nonwoven fabric having a strip tensile of at least 45 grams-force per centimeter per grams per square meter.
A nonwoven fabric, comprised of first and second layers, said first layer comprising a plurality of essentially continuous thermoplastic filaments, said thermoplastic filaments imparted with a three-dimensional image by impingement of fluid streams, said nonwoven fabric having a strip tensile of at least 45 grams-force per centimeter per grams per square meter, and said second layer comprising at least one material selected from the group consisting of un-imaged nonwoven fabrics, un-imaged woven fabrics, un-imaged knitted fabrics, imaged nonwoven fabrics, imaged woven fabrics, imaged knitted fabrics, pulp tissues, planar films, apertured films, scrims, supporting sublayers, and the combinations thereof.
