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.
Claims8
A disposable undergarment comprising:
- a covering member having a crotch region, a front waist region, a rear waist region, and transversely opposed side edges which are connected together to as to form a waist-opening having a peripheral edge and a pair of leg-openings;
- and
- a sweat-absorbent sheet provided inside of said peripheral edge of said waist-opening and located exclusively in an upper portion of at least one of said front waist region and said rear waist region, said sweat-absorbent sheet comprising:
- an inner layer for contacting with a wearer's skin;
- and
- an outer layer opposed to the inner layer,
- said inner layer containing about 70 to about 98 wt. % of hydrophobic fibers and at least 2 wt. % of hydrophilic fibers and said outer layer containing about 50 to about 100 wt. % of hydrophilic fibers with a portion of said hydrophilic fibers in said outer layer extending outward from said outer layer through interstices of said hydrophobic fibers of said inner layer to a skin contacting surface of said inner surface.
