대표청구항 ▼

1. 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; anda 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. 2. The disposable absorbent article of claim 1, wherein the male component is located in a rear region of the disposable absorbent article, and the first area is located in a front region of the disposable absorbent article. 3. The disposable absorbent article of claim 1, wherein the peak shear force to disengage the male component from the first area is at least 20% less than the force to disengage the male component from the second area. 4. The disposable absorbent article of claim 1, wherein the first area is at least 10% of a total area of the female component. 5. The disposable absorbent article of claim 4, wherein the first area is at least 20% of the total area of the female component. 6. The disposable absorbent article of claim 4, wherein the first area is less than 80% of the total area of the female component. 7. The disposable absorbent article of claim 1, wherein the first area comprises a point-unbonded spunbond web in which each discrete unbonded area is surrounded by the continuous bonded areas. 8. 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; anda 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. 9. The disposable absorbent article of claim 8, wherein the male component is located in a rear region of the disposable absorbent article, and the first area is located in a front region of the disposable absorbent article. 10. The disposable absorbent article of claim 8, wherein the peak shear force to disengage the male component from the first area is at least 20% less than the force to disengage the male component from the second area. 11. The disposable absorbent article of claim 8, wherein the first area is at least 10% of a total area of the backsheet. 12. The disposable absorbent article of claim 11, wherein the first area is at least 20% of the total area of the backsheet. 13. The disposable absorbent article of claim 11, wherein the first area is less than 80% of the total area of the backsheet. 14. The disposable absorbent article of claim 8, wherein the first area comprises a point-unbonded spunbond web in which each discrete unbonded area is surrounded by the continuous bonded areas.
