In sanitary napkins, the ADL (Acquisition Distribution Layer) plays a crucial role in fast liquid acquisition, even distribution, and reduced rewet, enhancing comfort and dryness. Specifically, its functions include:

1. Accelerating liquid absorption: ADL quickly guides menstrual fluid into the absorbent core, reducing surface wetness and improving dryness.

2. Evenly distributing liquid: It helps disperse the fluid evenly throughout the core, preventing localized over-absorption and leakage.

3. Minimizing rewet: High-quality ADL materials lower rewet rates, ensuring the skin remains dry and comfortable.

4. Enhancing absorbent core efficiency: By evenly distributing fluid, ADL improves the utilization of the absorbent materials, reducing side leakage risks.
