What is the fluff in baby diapers?

The fluff in baby diapers is typically made of absorbent materials, primarily fluff pulp derived from wood fibers. This fluff is designed to absorb moisture and keep the baby's skin dry. It works in conjunction with superabsorbent polymers (SAP) to lock away liquid, preventing leaks and ensuring comfort. The fluff helps maintain the diaper's overall structure while providing effective absorption.
