A pants-type wearing article in which at least a central segment of a crotch region has a desired degree of flexibility and a portion of a crotch region close to a front waist region has a desired degree of tensile strength. The front and rear waist regions and at least a portion of the crotch region close to the front waist region define a multilayer zone composed of a base sheet and a front waist sheet layered with each other and a central segment of the crotch region defines a monolayer zone formed of the base sheet alone. The multilayer zone includes corners each surrounded by a boundary, an inner end of the front waist region, a joint region in which a liquid-absorbent structure is bonded to a chassis and a concave lateral edge of the crotch region and the boundary extends across the joint region.

Pants-type wearing article

A disposable absorbent article includes a chassis and a liquid-absorbent structure. The chassis has an inner sheet lying on a skin-facing side and an outer sheet lying on a garment-facing side. The outer sheet has a first outer sheet and a second outer sheet lying inside the first outer sheet. The second outer sheet is formed on its outer surface with a display area extending in a longitudinal direction. The liquid-absorbent structure is formed with a central void and lateral voids in which core material for a core is not present. The display area can be visually recognized from the garment-facing side through the first outer sheet and from the skin-facing side also through the central void of the liquid-absorbent structure.

Embodiments of this invention provide a disposable wearing article facilitating even an aged person having relatively weak forth to pull a waist-opening periphery in the transverse direction to widen the waist-opening to a desired size, despite this and the waist region should not slip down during use of the wearing article. Waist elastic elements () are stretched in the transverse direction X at a stretch ratio in a range of about 2.5 to about 3.0 and having fineness in a range of about 800 to about 1000 dtex, a dimension between the waist elastic elements () adjacent in the transverse direction X is in a range of about 5.5 to about 6.0 mm and each of waist elastic regions () in which the waist elastic elements () are present has a tensile stress at a moment of 255% stretching in the transverse direction X in a range of about 4.5 to about 6.0N/35 mm and a tensile stress at a moment of 167% stretching in the transverse direction is in a range of about 1.7 to about 2.1N/35 mm.
