The keywords indicate a focus on maintaining structural integrity of absorbent channels and wetness indicators during use. Preventing the shifting or collapse of these internal structures ensures consistent fluid transport and accurate signaling.

The keywords focus on mechanical integration and bonding between layers to prevent the absorbent core from shifting, bunching, or breaking apart when wet. Maintaining structural stability ensures consistent fluid distribution and prevents leakage.

The integration of multi-layer cushions and composite topsheets addresses the failure of single-layer absorbent cores to manage fluid flow without leakage or surface wetness. Solving this prevents skin irritation and improves product integrity during use.
