ABSORBENT ARTICLE WITH TOPSHEET TREATED TO REDUCE SURFACTANT MIGRATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18450459 titled 'ABSORBENT ARTICLE WITH TOPSHEET TREATED TO REDUCE SURFACTANT MIGRATION

Simplified Explanation

- The patent application describes an absorbent article, such as a diaper or sanitary pad, with a topsheet that has been treated to repel liquid. - The topsheet is joined to a backsheet, with an absorbent core in between. - The absorbent core has an inner surface that faces the wearer's skin and an outer surface that faces the wearer's garment. - A surfactant, which is a substance that reduces surface tension, is applied to at least a portion of the outer surface of the topsheet. - The surfactant is applied specifically to the areas of the topsheet that have been treated to repel liquid. - The combination of the hydrophobic treatment and the hydrophilic surfactant helps to improve the overall performance of the absorbent article in terms of liquid absorption and leakage prevention.
