Abstract
A composite sheet that includes a first sheet and a second sheet is disclosed. The first and second sheets are bonded to each other at a number of spaced apart discrete inter-sheet bond locations. The first sheet is a nonwoven material that has discrete three-dimensional deformations therein forming protrusions that extend outward from the first surface of the first sheet to their distal ends and wide base openings adjacent to the second surface of the first sheet. The second sheet is a generally planar sheet that contacts the distal ends of the protrusions on the first sheet. The second sheet is bonded to the first sheet at spaced apart inter-sheet bond locations where the first region of the first sheet contacts the second sheet.
