Abstract

Liner composites suitable for incorporation into a variety of disposable absorbent articles. The liner composites included a liner material and a topographical surge.

Claims

1. A liner composite comprising:

a fluid pervious liner having a bodyfacing surface and a lower surface;

a topographical surge material having a bodyfacing surface, and a plurality of topographical features, at least a portion of the bodyfacing surface of the topographical surge material in facing relationship with at least a portion of the lower surface of the fluid pervious liner;

wherein at least a portion of the topographical features are imparted onto the bodyfacing surface of the fluid pervious liner, and a plurality of the topographical features imparted onto the bodyfacing surface of the fluid pervious liner have an amplitude of greater than about 2.5 mm.

2. The liner composite of claim 1, wherein a plurality of the topographical features imparted onto the bodyfacing surface of the fluid pervious liner have an amplitude of greater than about 5 mm.

3. The liner composite of claim 1, wherein a plurality of the topographical features imparted onto the bodyfacing surface of the fluid pervious liner have an amplitude of greater than about 15 mm.

4. The liner composite of claim 1, wherein at least a portion of the topographical surge is attached to at least a portion of the fluid pervious liner by adhesive, cohesive, thermal, pressure, or ultrasonic bonds.

5. The liner composite of claim 1, wherein the fluid pervious liner has a caliper of less than about 4 mm.

6. The liner composite of claim 1, wherein at least a portion of the fluid pervious liner is coapertured with the topographical surge material.

7. The liner composite of claim 1, wherein the fluid pervious liner comprises a plurality of apertures.

8. The liner composite of claim 7, wherein at least a portion of the plurality of apertures have at least one dimension greater than about 0.25 millimeters.

9. The liner composite of claim 7, wherein at least a portion of the plurality of apertures have at least one dimension greater than about 0.5 millimeters.

10. The liner composite of claim 7, wherein at least a portion of the plurality of apertures have at least one dimension greater than about 1.0 millimeters.

11. The liner composite of claim 1, wherein a plurality of the topographical features imparted onto the bodyfacing surface of the fluid pervious liner have a wavelength of between about 5 mm and about 25 mm.

12. The liner composite of claim 1, wherein the fluid pervious liner has an area, the topographical surge material has an area, and the ratio of the area of the topographical surge material to the area of the fluid pervious liner is no greater than about 0.75.

13. The liner composite of claim 12, wherein the ratio of the area of the topographical surge material to the area of the fluid pervious liner is no greater than about 0.5.

14. The liner composite of claim 12, wherein the ratio of the area of the topographical surge material to the area of the fluid pervious liner is no greater than about 0.1.

15. The liner composite of claim 1, further comprising a second surge material in facing relationship with at least a portion of the lower surface of the fluid pervious liner, wherein the topographical surge material is dissimilar from the second surge material.

16. A disposable absorbent article comprising:

a liquid impervious backing sheet;

a fluid pervious liner having a bodyfacing surface and a lower surface;

an absorbent core disposed between the fluid pervious bodyside liner and the liquid impervious backing sheet; and

a topographical surge material having a plurality of topographical features, the topographical surge material disposed between the absorbent core and the fluid pervious bodyside liner;

wherein at least a portion of the topographical features are imparted onto the bodyfacing surface of the fluid pervious liner, and a plurality of the topographical features imparted onto the bodyfacing surface of the fluid pervious liner have an amplitude of greater than about 2.5 mm.

17. The disposable absorbent articles of claim 16, wherein the topographical surge has a basis weight of greater than about 30 gsm.

18. The disposable absorbent articles of claim 16, wherein the topographical surge has a basis weight of at greater than about 50 gsm.

19. The disposable absorbent articles of claim 16, wherein the topographical surge comprises a nonwoven material having a basis weight of at greater than about 30 gsm.

20. The disposable absorbent article of claim 16, wherein a plurality of the topographical features imparted onto the bodyfacing surface of the fluid pervious liner have an amplitude of greater than about 5 mm.

21. The disposable absorbent article of claim 16, wherein a plurality of the topographical features imparted onto the bodyfacing surface of the fluid pervious liner have an amplitude of greater than about 15 mm.

22. The disposable absorbent article of claim 16, wherein at least a portion of the topographical surge is attached to at least a portion of the fluid pervious liner by adhesive, cohesive, thermal, pressure or ultrasonic bonds.

23. The disposable absorbent article of claim 16, wherein the fluid pervious liner has a caliper of less than about 4 mm.

24. The disposable absorbent article of claim 16, wherein at least a portion of the fluid pervious liner is coapertured with the topographical surge material

25. The disposable absorbent article of claim 16, wherein the fluid pervious liner comprises a plurality of apertures.

26. The disposable absorbent article of claim 25, wherein at least a portion of the plurality of apertures have at least one dimension greater than about 0.25 millimeters.

27. The disposable absorbent article of claim 25, wherein at least a portion of the plurality of apertures have at least one dimension greater than about 0.5 millimeters.

28. The disposable absorbent article of claim 25, wherein at least a portion of the plurality of apertures have at least one dimension greater than about 1.0 millimeters.

29. The disposable absorbent article of claim 16, wherein a plurality of the topographical features imparted onto the bodyfacing surface of the fluid pervious liner have a wavelength of between about 5 mm and about 25 mm.
