Elastic multilayer composite including pattern unbonded elastic materials, articles containing same, and methods of making same

1. An elastic multilayer composite comprising:

a first extensible facing material; and,

an elastic layer attached to the facing material, wherein the elastic layer comprises a continuous bonded region defining a plurality of discreet, fibrous regions being less bonded than the continuous bonded region, and further wherein the extensible facing does not have a continuous bonded region corresponding to the elastic layer continuous bonded region.

2. The elastic multilayer composite of claim 1 , wherein the continuous bonded region is a continuous film.

3. The elastic multilayer composite of claim 1 , wherein the elastic layer is positioned between and attached to the first extensible facing material and a second extensible facing material.

4. The elastic multilayer composite of claim 1 , wherein the first facing material comprises a breathable film.

5. The elastic multilayer composite of claim 3 , wherein the second extensible facing material is a nonwoven fabric.

6. The elastic multilayer composite of claim 1 , wherein the elastic layer is an extruded meltblown web.

7. The elastic multilayer composite of claim 3 , wherein the second facing material comprises a nonwoven fabric.

8. The elastic multilayer composite of claim 1 , wherein the elastic multilayer composite is extensible and elastic in the machine direction.

9. The elastic multilayer composite of claim 1 wherein the elastic multilayer composite is extensible and elastic in the cross-machine direction.

10. A method of making an elastic multilayer composite comprising the steps of:

forming an elastic fibrous fabric;

feeding the elastic fibrous fabric into a nip defined between opposedly positioned first and second rollers, said first roller having a patterned outer surface and said second roller having a smooth outer surface;

bonding the elastic fibrous fabric to form on a surface thereof a continuous bonded region defining a plurality of discrete fibrous regions to form a pattern unbonded elastic sheet;

attaching a first facing material to the pattern unbonded elastic sheet.

11. The method of claim 10 further comprising the step of stretching the pattern unbonded elastic sheet by from about 10% to about 500% prior to attaching the first facing material to the pattern unbonded elastic sheet.

12. The method of claim 10 wherein the first facing material comprises a film.

13. The method of claim 12 wherein the film is breathable.

14. The method of claim 10 further comprising the step of necking the first facing material prior to attaching the first facing material to the pattern unbonded elastic sheet.

15. The method of claim 10 further comprising bonding a second facing material to the pattern unbonded elastic sheet wherein the pattern unbonded elastic sheet is positioned between the first and second facing materials.

16. The method of claim 10 , wherein the elastic fibrous fabric is an extruded meltblown web.

17. The method of claim 12 wherein the film is slit or apertured.

18. The method of claim 10 wherein the bonding is accomplished by application of heat or pressure.

19. The method of claim 11 wherein the stretching is in the machine direction.

20. The method of claim 10 further comprising the step of stretching the elastic fibrous fabric by from about 10% to about 500% prior to bonding the elastic fibrous fabric to form on a surface thereof a continuous bonded region defining a plurality of discrete fibrous regions to form a pattern unbonded elastic sheet.

21. An elastic multilayer composite produced by the method of claim 10 .

22. An article selected from the group consisting of personal care products, safety garments, and medical products comprising the composite of claim 21 .
