AI Technical Summary

Technical Problem

Existing sanitary pads have limited absorbency, which cannot meet the needs of women with urinary incontinence, and they cannot lock in the odor produced by urine, resulting in odor.

Method used

An incontinence-eliminating odor-removing sanitary pad was designed, which uses activated carbon particles to absorb odors and combines them with hot-air nonwoven fabric. The bottom surface of the breathable membrane is recessed with absorbent particles, including: absorbent particles, first absorbent particles, a cotton soft surface layer, a flow-guiding layer, and an anti-seepage layer. The absorbent particles are located above the flow-guiding layer, and the anti-seepage layer is located below the flow-guiding layer. The top surface of the flow-guiding layer is recessed with a first filling groove and a second filling groove. The absorbent particles and absorbent particles are respectively filled in their respective filling grooves. There is fluff pulp between the flow-guiding layer and the anti-seepage layer, and the cotton soft surface layer has flow-guiding holes.

Benefits of technology

It increases absorbency, reduces urine leakage and odor, and improves the user experience.
