- 8. A breathable composite web comprising:
a microporous film; and a nonwoven web joined to said microporous film in a face-to-face relationship to form a composite web; wherein said composite web has an MVTR of at least about 2000 g/m2/24 hr, a dynamic fluid impact value of less than about 10 g/m2, and a bubble pressure of at least about 45 psi.
- 9. The breathable composite web of claim 8 further comprises a plurality of first regions and a plurality of second regions adjacent to said first regions, wherein the second regions comprises raised rib-like elements.
- 10. The breathable composite web of claim 9 having a percent set of at least about 40 percent.
- 11. The breathable composite web of claim 10 having a percent set ranging from about 40 percent to about 120 percent.
- 12. The breathable composite web of claim 8 wherein the microporous film has a mean pore size less than about 0.3 microns.
- 13. The breathable composite web of claim 8 wherein the microporous film comprises a thermoplastic polymer selected from the group consisting of polyolefins and copolymers, polyesters and copolymers, polyurethanes and copolymers, polyamides and copolymers and mixtures thereof, and a pore forming agent dispersed therein; and the nonwoven web comprises fibers selected from the group consisting of polyolefins and copolymers, polyesters and copolymers, polyamide and copolymers, cellulose derivatives, and mixtures thereof.
- 14. A disposable absorbent article comprising a topsheet that faces the body of the wearer when the article is worn, a backsheet that faces away from the body of the wearer when the article is worn, and an absorbent core positioned between the topsheet and the backsheet, wherein the article includes a component having as an element thereof the breathable web of claim 1.
- 15. A disposable absorbent article comprising a topsheet that faces the body of the wearer when the article is worn, a backsheet that faces away from the body of the wearer when the article is worn, and an absorbent core positioned between the topsheet and the backsheet, wherein the article includes a component having as an element thereof the breathable web of claim 3.
- 16. A disposable absorbent comprising a topsheet that faces the body of the wearer when the article is worn, a backsheet that faces away from the body of the wearer when the article is worn, and an absorbent core positioned between the topsheet and the backsheet, wherein the article includes a component having as an element thereof the breathable composite web of claim 8.
- 17. A disposable absorbent article comprising a topsheet that faces the body of the wearer when the article is worn, a backsheet that faces away from the body of the wearer when the article is worn, and an absorbent core positioned between the topsheet and the backsheet, wherein the article includes a component having as an element thereof the breathable composite web of claim 9.
