Abstract
A disposable undergarment is provided on inside of a waist-opening's peripheral edge with a sweat-absorbent sheet comprising an inner layer destined to come in contact with a wearer's skin and an outer layer opposed to the inner layer. The inner layer contains hydrophobic fibers of 70˜98 w % and hydrophilic fibers of at least 2 w %. The outer layer contains hydrophilic fibers of 50˜100 w % of which a part extends outward from the outer layer through interstices of the hydrophobic fibers to the skin contacting surface of the inner surface.
