AI Technical Summary

⚠Technical Problem

Existing absorbent products have simple designs for the diversion layer and absorbent core layer, which easily leads to side leakage and difficulty in moisture dissipation. In addition, the surface layer has a large contact area with the skin, causing discomfort to users.

⚗Method used

The composite core structure includes a surface layer, a composite core, and a bottom film layer. The surface layer has protrusions and grooves. The composite core consists of multiple flow-guiding layers and a core, and uses highly absorbent materials. The bottom film layer is a hydrophobic PE film, and the release layer is a silicone oil layer and release paper. Inclined and vertical channels are designed to optimize liquid distribution.

🎯Benefits of technology

It improves absorption capacity and speed, reduces side leakage and backflow, increases absorption volume, improves user comfort, and solves the problem of moisture and heat not dissipating easily.
