Abstract
A disposable training pant 1 includes a liquid-permeable topsheet, a liquid-impermeable backsheet and an absorbent core disposed therebetween. The liquid-permeable tophseet includes an upper layer sheet and a lower layer sheet. The upper layer sheet is formed with a wetness telling area and the lower layer sheet intermittently bonded to the absorbent core 13 and containing fibrous material adapted to shrink by 10% or more longitudinally of the training pant as it is wetted and intermittently bonded to the absorbent core and thereby intensify a feeling of wetness given to the infant.
Claims9
A disposable training pant comprising a liquid-permeable topsheet, a liquid-impermeable backsheet and a liquid-absorbent core extending therebetween which form a front waist region, a rear waist region and a crotch region extending therebetween said topsheet being intermittently bonded to said absorbent core and bonded to said backsheet at portions of said topsheet and said backsheet extending outward beyond a peripheral edge of said absorbent core, wherein:
- said topsheet contains a fibrous material causing at least a longitudinal dimension of said crotch region to shrink by at least 10% as said topsheet is wetted so that said topsheet can shrink at least longitudinally of said crotch region and at least a shrinkable area of said topsheet can peel off upward from said absorbent core and wherein a predetermined area of said topsheet has a hydrophilicity higher than that in the area extending around said predetermined area and thereby defines a wetness telling area.
