| 摘要 |
<p>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.</p> |
