  • the inseam area was not sufficiently raised, and the inseam area was liable to hang down due to the weight of the absorption core that absorbed the excrement, especially after excretion. Since the inseam area hangs down, the absorption core is separated from the wearer's body, which may cause lateral leakage of excrement.

  • the absorber in the low basis weight region is relatively difficult to swell even if the absorber absorbs excrement. Therefore, the contraction of the continuous elastic member is less likely to be hindered even after excretion, and the first waist circumference region can be fitted to the wearer's body even after excretion.
