Claims14
A disposable absorbent article comprising:
- an outer cover having a bodyfacing surface and a garment facing surface;
- a liner superposed over the bodyfacing surface of the outer cover, the outer cover comprising a substantially continuous outer cover nonwoven web;
- an absorbent core disposed between the liner and the bodyfacing surface of the outer cover;
- and
- a fastening system, the fastening system comprising a male component having a plurality of hook elements and a female component adapted for releasable engagement with the male component,
- wherein the outer cover nonwoven web forms the female component, such that the male component is releasably engageable directly with the garment facing surface of the outer cover,
- wherein the female component contains at least a first area and a second area, wherein the first area is modified by embossing a surface of the female component contacted by the male component, and wherein the first area comprises continuous bonded areas that define a plurality of discrete unbonded areas,
- wherein a peak shear force to disengage the male component from the first area is reduced by no less than 5% and no more than 70% of a peak shear force to disengage the male component from the second area.

A disposable absorbent article, the article having a bodyfacing surface and a garment facing surface, the article comprising:
- a backsheet that comprises a substantially continuous nonwoven web, the backsheet including a bodyfacing surface and a garment facing surface;
- an absorbent core disposed on the bodyfacing surface of the backsheet;
- and
- a fastening system comprising a male component disposed on the bodyfacing surface of the article, the male component adapted for direct releasable engagement with the garment facing surface of the backsheet,
- wherein the backsheet contains a first area and a second area, wherein the first area is modified by embossing a surface of the female component contacted by the male component, wherein the first area comprises continuous bonded areas that define a plurality of discrete unbonded areas,
- wherein a peak shear force to disengage the male component from the first area is reduced by no less than 5% and no more than 70% of a peak shear force to disengage the male component from the second area.
