Abstract

Official abstract text for this publication.

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 ( 36 ) 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 ( 36 ) 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 ( 38 ) in which the waist elastic elements ( 36 ) 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.

First claim
