Abstract

DC60 (31/01/43) has revealed absorbent materials, including layered parts, including the top plate that allow Liquid permeable, the back plate and the absorbent core are arranged between the top plate and the back plate. The area where the adsorbent is present, including the central region that extends along the longitudinal direction of the absorbent, and The lateral area is aligned with the central region in the longitudinal direction perpendicular to the longitudinal direction. The bending resistance (stiffness) of the stacked part in the middle region is higher than the bending resistance of the part that Stacked in a lateral area Adsorbents can be attached in a stable fit. Without warping or wrinkling, when absorbent material is superimposed on the inner surface of the outerwear, absorbent materials, including layered parts, including Top sheet that allows Liquid permeable, the back plate and the absorbent core are arranged between the top plate and the back plate. The area where the adsorbent is present, including the central region that extends along the longitudinal direction of the absorbent, and The lateral area is aligned with the central region in the longitudinal direction perpendicular to the longitudinal direction. The bending resistance (stiffness) of the stacked part in the middle region is higher than the bending resistance of the part that Stacked in a lateral area Adsorbents can be attached in a stable fit. There is no warping or wrinkling when the absorbent is superimposed on the inner surface of the outer wear.
