9. The mechanical fastening system of claim 1 , wherein the fibrous web has a coefficient of friction of at least about 0.65 grams when rubbed against a smooth back side of a hook material in accordance with the Coefficient Of Friction Test Method.
10. The mechanical fastening system of claim 1 , wherein the fibrous web has a coefficient of friction of at least 0.7 grams when rubbed against a smooth back side of a hook material in accordance with the Coefficient Of Friction Test Method.
11. The mechanical fastening system of claim 1 , wherein the fibrous web is attached to a non-elastomeric base layer.
12. The mechanical fastening system of claim 1 , wherein the fibrous web is substantially free of reticulated polyurethane foam material.
13. The mechanical fastening system of claim 1 , wherein the fibrous web is substantially free of foam material.
14. A disposable absorbent article comprising:
a chassis comprising a bodyside liner and a garment-side outer cover,
an absorbent assembly sandwiched between the liner and the outer cover;
a mechanical fastening system comprising:
a male component having a plurality of male engaging elements;
a female component having a plurality of female engaging elements adapted for releasable direct engagement with the male engaging elements, wherein the female engaging elements comprise elastomeric fibers, wherein the elastomeric fibers together define a fibrous web.
15. The disposable absorbent article of claim 14 , wherein the fibrous web is a woven material.
16. The disposable absorbent article of claim 14 , wherein the fibrous web is a nonwoven material.
17. The disposable absorbent article of claim 16 , wherein the fibrous web is a spunbond web.
18. The disposable absorbent article of claim 14 , wherein the fibers are bicomponent fibers.
19. The disposable absorbent article of claim 18 , wherein the fibers have an elastomeric core and a substantially non-elastomeric sheath.
20. The disposable absorbent article of claim 14 , wherein the fibrous web has a coefficient of friction of at least about 0.5 grams when rubbed against a Plexiglas® material in accordance with the Coefficient Of Friction Test Method.
21. The disposable absorbent article of claim 14 , wherein the fibrous web has a coefficient of friction of at least 0.65 grams when rubbed against a Plexiglas® material in accordance with the Coefficient Of Friction Test Method.
22. The disposable absorbent article of claim 14 , wherein the fibrous web has a coefficient of friction of at least about 0.65 grams when rubbed against a smooth back side of a hook material in accordance with the Coefficient Of Friction Test Method.
23. The disposable absorbent article of claim 14 , wherein the fibrous web has a coefficient of friction of at least 0.7 grams when rubbed against a smooth back side of a hook material in accordance with the Coefficient Of Friction Test Method.
24. The disposable absorbent article of claim 14 , wherein the fibrous web is attached to a non-elastomeric base layer.
25. The disposable absorbent article of claim 14 , wherein the fibrous web is substantially free of reticulated polyurethane foam material.
26. The disposable absorbent article of claim 14 , wherein the fibrous web is substantially free of foam material.
27. The disposable absorbent article of claim 14 , wherein the fibrous web is integral with the outer cover.
28. The disposable absorbent article of claim 27 , wherein the first and second fibrous webs are respectively bonded to the first and second side panels.
29. The disposable absorbent article of claim 14 , wherein the fibrous web is integral with the liner.
30. The disposable absorbent article of claim 14 , wherein the disposable absorbent article further comprises first and second side panels extending from opposite lateral sides of the absorbent chassis, wherein a first fibrous web is disposed on the first side panel and a second fibrous web is disposed on the second side panel, wherein the first and second fibrous webs are respectively disposed on the first and second side panels.
