Abstract
A disposable undergarment that has a pair of tape fasteners attached to transversely opposite side edge portions of a rear waist region and a non-stretchable target tape strip attached to the outer surface of a front waist region. The front and rear waist regions and a crotch region are elastically stretchable in length and width. The tape strip includes a flexible plastic sheet having transversely opposite side edges extending longitudinally and upper and lower edges extending transversely of the undergarment and a plurality of long fibers extending longitudinally on the outer surface of the sheet between the upper and lower edges. The sheet is formed with a plurality of perforated lines arranged to be transversely spaced one from another by a predetermined dimension and to extend between the vicinity of the upper edge and the vicinity of the lower edge. The target tape strip is attached to the front waist region being substantially in non-stretched state. The long fibers are bonded to the sheet by means of sealing zones transversely extending in the vicinity of the upper and lower sides of the sheet.
