Abstract:
1. An absorbent product comprising a liquid-impermeable backsheet, a liquid-permeable topsheet including a core-facing surface and a wearer-facing surface, and an absorbent core structure located between said topsheet and said backsheet, said absorbent core structure including a topsheet-facing surface, wherein said topsheet-facing surface is fixedly attached to said topsheet over at least 10% of the surface area of said topsheet-facing surface, wherein a low friction material zone includes a low friction material arranged between said topsheet and said topsheet-facing surface in an area where said topsheet is unattached to said topsheet-facing surface, wherein said absorbent product is a disposable absorbent diaper including a waist region at either end thereof joined by a crotch region, and said low friction material zone is positioned at least partly in one of said waist regions, wherein said low friction material zone is limited to a surface area of less than 50% of said absorbent product surface area, wherein friction between the wearer-facing surface and a wearer's skin is higher than friction between a layer in contact with the low friction material and the low friction material in the absorbent product.
