Abstract

A composite material includes a nonwoven layer having a plurality of fibers and a polymer film layer with a plurality of extended cells. Each of the extended cells are contemplated to include continuous sidewalls extending away from the nonwoven layer. At least one of the fibers extends into one or more of the extended cells.

Claims (10)

1. A composite material comprising:

a nonwoven layer comprising a plurality of fibers; and

a polymer film layer laminated to the nonwoven layer, the polymer film layer comprising a plurality of apertured extended cells, each of the apertured extended cells having continuous sidewalls extending away from the nonwoven layer, wherein a portion of at least one of the fibers extends into one or more of the apertured extended cells and through an aperture at a distal end of at least one of the apertured extended cells, and wherein the apertured extended cells have a mesh count of between 3 cells per linear inch and about 120 cells per linear inch.

2. The composite material according to claim 1 , wherein the apertured extended cells are micro-cells having a mesh count of between about 40 cells per linear inch and about 120 cells per linear inch.

3. The composite material according to claim 2 , further comprising a plurality of apertures extending through the nonwoven layer and the polymer film layer and having a mesh count of less than about 40 cells per linear inch.

4. The composite material according to claim 3 , wherein the plurality of apertures have a mesh count of between about 3 cells per linear inch and about 25 cells per linear inch.

5. The composite material according to claim 1 , further comprising a plurality of apertures extending through the nonwoven layer and the polymer film layer.

6. The composite material according to claim 1 , further comprising an embossed three-dimensional pattern.

7. The composite material according to claim 1 , wherein the nonwoven layer comprises a surfactant.

8. The composite material according to claim 7 , wherein the fibers comprise the surfactant.
