Abstract
The present invention relates to a soft feeling, aesthetically pleasing, and form-fitting disposable nonwoven undergarment for men, women, and youths, and optionally comprises a protective panel for those individuals with mild incontinence conditions.
Most disposable undergarments currently available are awkward, noisy, or comprise unpleasant fasteners. It is the object of the present invention to provide a comfortable, durable disposable undergarment by forming the undergarment of a three-dimensionally imaged nonwoven fabric.

- 17. A disposable nonwoven undergarment hydroentangled on a foraminous surface comprising a front panel, back panel, and an interconnecting crotch region, wherein said front panel, back panel, and interconnecting crotch region are mechanically secured together at their transverse edges forming an upper waist and lower leg regions.
- 21. A disposable nonwoven undergarment hydroentangled on a foraminous surface comprising a unitary hourglass-shape construct, wherein the front panel and back panel are integrally joined with an interconnecting crotch region and mechanically secured together at their transverse edges forming an upper waist and lower leg regions.

26. An absorbent panel construct for use in an absorbent article to prevent human exudates from transversely leaking through the sides of said absorbent article comprising an upper layer and lower layer, wherein said upper and lower layers are comprised of a front region, a back region, and two side regions;
- said layers mechanically secured along said front region, back region, and at least 50% secured along said side regions of said panel, whereby a portion of said side regions of said upper and lower layers remain essentially unattached to form a distinct zone a separation.
