NONWOVEN MATERIAL HAVING DISCRETE THREE-DIMENSIONAL DEFORMATIONS WITH WIDE BASE OPENINGS AND SPECIFIC FIBER CONCENTRATIONS

摘要

Nonwoven materials having discrete three-dimensional deformations therein forming protrusions that extend outward from the first surface of the nonwoven material and wide base openings adjacent to the second surface of the nonwoven material are disclosed. The nonwoven materials are made of at least two layers that include at least a first nonwoven layer and a second nonwoven layer. Portions of the fibers in each layer form part of the undeformed first region, the side walls of the protrusions, and the distal ends of the protrusions. There may be differences in the concentration of fibers, or other properties, within at least one of the first and second layers in each of these parts of the deformed nonwoven material.
