Abstract:
1. A pants-type disposable wearing article having a longitudinal direction, a transverse direction being orthogonal to said longitudinal direction, a skin-facing side and a non-skin-facing side, said wearing article comprising: a front waist region, a rear waist region and a crotch region extending between said front and rear waist regions, wherein at least one of said front and rear waist regions comprises an inner sheet lying on the skin-facing side and an outer sheet lying on the non-skin-facing side, wherein said inner sheet has a contractile force higher than that of said outer sheet at least in said transverse direction, opposite lateral sections of said inner and outer sheets are permanently bonded together, arrays of side seam spots extend in said longitudinal direction and join the front and rear waist regions to one another, opposite lateral sections of said front and rear waist regions extend outward in said transverse direction from said arrays of side seam spots to form respective pairs of front and rear flaps, which are curled inwardly so as to define protruding rims outside said arrays of side seam spots, the inner sheet has a lower stiffness than the outer sheet bonded to said inner sheet, a cantilever measured stiffness value of the outer sheet is in a range of 35 to 40 mm in a machine direction and in a range of 30 to 35 mm in a direction orthogonal to the machine direction, and a cantilever measured stiffness value of the inner sheet is in a range of 12 to 17 mm in the machine direction and in a range of 15 to 20 mm in the direction orthogonal to the machine direction.
