The keywords focus on mechanical integration and partial bonding between layers to prevent the structural failure of the absorbent core during use. Improving interlayer adhesion ensures the article maintains its shape and fluid distribution capacity under mechanical stress.

The keywords highlight material movement and the need for swelling chambers within the core. This indicates a failure where superabsorbent particles shift or clump during use, leading to poor fluid distribution and core instability.

Standard absorbent cores often suffer from fluid pooling or leakage due to poor structural integration. Optimizing the multi-layered architecture prevents saturation bottlenecks and improves liquid transport across the article.
