ABSTRACT:
The stretchable undergarment comprises a liquid-previous bodyside layer, liquid-impervious outer layer, an absorbent layer, and a stretchable layer. The stretchable layer is stretch-bonded to the other layers and, upon relaxing the stretchable layer forms a plurality of rugosities in the bodyside layer, outer layer, and absorbent medium. The bonded layers are of a generally trapezoidal shape and have a front end portion that diverges toward a rear end portion, wherein the front end portion is from about 20% to about 90% of the width of the rear end portion, and the rear end portion is about 20% to about 60% of the length of the bonded layers.
