Structural elastic-like nonwoven web
Disclosed is a nonwoven web comprising a plurality of first regions and a plurality of second regions comprised of the same material and being visually distinct from each other, wherein the first regions will exhibit resistive forces in response to an applied elongation along at least one axis before a substantial portion of the second regions develop significant resistive forces to the applied elongation.
1. A structural elastic-like laminate comprising a nonwoven web inner layer and a film web outer layer, the laminate comprising
a plurality of first regions and a plurality of second regions comprising the same material and being visually distinct from each other, wherein the first regions exhibit resistive forces in response to an applied elongation along at least one axis before a substantial portion of the second regions develop resistive forces to the applied elongation, and wherein the resistive forces occur without the use of elastic material.
2. The laminate of claim 1 wherein the first regions are substantially planar.
3. The laminate of claim 1 wherein the second regions comprise rib-like elements.
4. A disposable absorbent article comprising the laminate of claim 1 .
5. The disposable absorbent article of claim 4 wherein the laminate is a backsheet.
6. The disposable absorbent article of claim 4 wherein the laminate is a leg cuff.
7. A structural elastic-like laminate comprising a nonwoven web inner layer and a film web outer layer, the laminate:
exhibiting at least two stages of resistive forces, without the use of elastic material, to an applied axial elongation along at least one axis when subjected to the applied axial elongation in a direction substantially parallel to the axis, the laminate comprising a strainable network of visually distinct regions, said strainable network including at least a first region which is substantially planar and a second region containing rib-like elements, said first region and said second region comprising the same material composition.
8. A disposable absorbent article comprising the laminate of claim 7 .
9. The disposable absorbent article of claim 8 wherein the laminate is a leg cuff.
10. The disposable absorbent article of claim 8 wherein the laminate is a backsheet.
11. A structural elastic-like laminate comprising a nonwoven web inner layer and a separate nonwoven web outer layer, the laminate comprising
a plurality of first regions and a plurality of second regions comprising the same material and being visually distinct from each other, said first regions undergoing substantially molecular-level or fiber-level deformation and said second regions initially undergoing a substantially geometric deformation when said nonwoven web is subjected to an applied elongation along at least one axis and wherein said deformation occurs without the use of elastomeric material.
12. The laminate of claim 11 wherein the first regions are substantially planar.
13. The laminate of claim 11 wherein the second regions comprise rib-like elements.
14. The laminate of claim 11 wherein said nonwoven web material has a first surface and an opposite facing second surface.
15. The laminate of claim 14 wherein the first regions comprise from about 10% to about 90% of said first surface.
16. The laminate of claim 11 wherein the applied elongation is between 10 and 25%.
17. A disposable absorbent article comprising the laminate of claim 11 .
18. The disposable absorbent article of claim 17 wherein the laminate is a topsheet.
19. The disposable absorbent article of claim 17 wherein the laminate is a core.
