Abstract
The present disclosure provides three-dimensional materials having apertures. The apertures in the three-dimensional materials may be formed in portions of a generally planar region and/or in at least some of a plurality of discrete integral second regions. The apertures may help in BM or other bodily fluid acquisition and retention.
Claims22
A nonwoven material having a first surface and a second surface, the nonwoven material extending in an imaginary X-Y plane and comprising:
- a plurality of fibers,
- a generally planar first region;
- and
- a plurality of discrete integral second regions that comprise deformations forming protrusions extending outward from the first surface of the nonwoven material and openings in the second surface of the nonwoven material, wherein the protrusions are formed from the fibers, wherein the protrusions have an exterior width, and two ends that define a length of the protrusions therebetween, and wherein the protrusions comprise a base proximate to the first surface of the nonwoven material, an opposed distal end extending outward in the Z-direction from the base, side walls between the base and the distal end of the protrusion, and a cap comprising at least a portion of the side walls and the distal end of the protrusion;
- wherein the side walls have interior surfaces, wherein the interior surfaces of the side walls define a base opening at the base of the protrusion, wherein the cap has a portion with a maximum interior width, wherein the base opening has a width, and wherein the maximum interior width of the cap of the protrusions is greater than the width of the base opening;
- and
- wherein a plurality of apertures are defined through the nonwoven material in portions of the generally planar first region or through portions of at least some of the plurality of discrete integral second regions, and wherein the apertures are formed in a predetermined, intentional pattern.

An absorbent article comprising:
- a liquid pervious nonwoven material having a first surface and a second surface, the nonwoven material extending in an imaginary X-Y plane and comprising a plurality of fibers, wherein the nonwoven material comprises a generally planar first region and a plurality of discrete integral second regions that comprise deformations forming protrusions extending outward from the first surface of the nonwoven material and openings in the second surface of the nonwoven material, the protrusions being formed from the fibers, wherein at least some of the protrusions have an exterior width, and two ends that define a length of the protrusion therebetween, wherein the at least some of the protrusions comprise a base proximate to the first surface of the nonwoven material, an opposed distal end extending outward in the Z-direction from the base, side walls between the base and the distal end of the protrusion, and a cap comprising at least a portion of the side walls and the distal end of the protrusion, wherein the side walls have interior surfaces, and wherein the exterior width of the protrusion varies along the length of the protrusion when viewed looking at the nonwoven material in a direction perpendicular to the X-Y plane of the nonwoven material;
- wherein a plurality of apertures are defined through the nonwoven material in portions of the generally planar first region or through portions of at least some of the plurality of discrete integral second regions, and wherein the apertures form a repeating pattern;
- a liquid impervious backsheet;
- and
- an absorbent core positioned at least partially intermediate the liquid pervious nonwoven material and the backsheet.
