AI Technical Summary
Technical Problem
Absorbent articles containing superabsorbent polymers face limitations in fluid absorption due to restricted swelling, leading to inadequate fluid uptake when divided into regions without superabsorbent polymer presence.
Method used
The absorbent article design includes embossed portions extending from the surface sheet to the absorbent, positioned at both ends of the width or longitudinal direction, allowing the superabsorbent polymer to swell and absorb fluids without restriction, with higher polymer basis weight in key regions.
Benefits of technology
Ensures sufficient fluid absorption by allowing the superabsorbent polymer to swell and expand, maintaining fit and absorption capacity regardless of fluid volume, preventing leakage and enhancing wearability.

Abstract
The present invention provides an absorbent article comprising an absorbent material containing a superabsorbent polymer, wherein the absorbent material containing the superabsorbent polymer is capable of ensuring sufficient absorption of body fluids. [Solution] The absorbent article 1 comprises a surface sheet 2, a first absorbent 4 disposed on the non-skin side of the surface sheet 2 and composed of an SAP sheet containing a superabsorbent polymer, and a second absorbent 5 disposed on the non-skin side of the first absorbent 4. The absorbent article 1 further comprises an embossed portion formed from the surface sheet 2 toward the first absorbent 4 and reaching at least the non-skin side surface of the first absorbent 4. When the first absorbent 4 is divided into three equal regions in the width direction W, the embossed portion includes a first embossed portion 13 located in the regions at both ends of the width direction W and extending along the longitudinal direction L.
