Sanitary Napkin Diversion Layer OEM: Fluid Distribution and Dryness Guide

The diversion layer, also called an acquisition or distribution layer, helps move liquid away from the topsheet and spread it into the absorbent core. It is a key detail for comfort, dryness and leakage control.

For OEM and private label buyers, product specification is the language that connects brand positioning, sample approval, factory production and shipment inspection. A clear specification reduces misunderstandings and makes repeat orders easier to control.

Why the diversion layer matters

Without good fluid distribution, liquid can stay near the surface or concentrate in one area. This affects wearing feel, rewet and side-leak risk.

• Faster acquisition from the topsheet.
• Better distribution across the core.
• Lower surface wetness after pressure.
• Improved performance for night or heavy-flow pads.

How to match it with the core

The diversion layer should match the topsheet speed, core length, SAP ratio and intended flow level. A high-performance layer cannot compensate for a poorly designed core.

Sample tests for buyers

Ask for absorption speed, rewet and leakage simulation results. Compare samples after liquid intake, not only by dry appearance.

FAQ for Product Specification Buyers

Is a diversion layer needed for every pad?

Not every SKU needs the same layer, but higher absorbency and overnight products benefit from better fluid distribution.

Can the layer be customized?

Yes. Material, thickness and structure can be adjusted depending on MOQ and product positioning.

What problem does it solve?

It helps reduce surface wetness and uneven absorption, improving comfort and leakage protection.
