Abstract

An absorbent article is disclosed, including a three-dimensional material formed of a liquid permeable topsheet and an acquisition material. The acquisition material is positioned beneath the topsheet, and both may be formed of nonwoven material. The three dimensional material may have two surfaces and a plurality of protrusions extending in a z-direction from one of the surfaces, each protrusion having side walls defining an opening in the other of the surfaces. One of the topsheet and the acquisition material may include fibers spun of polymer resin pigmented with a first color that differs from a second color of fibers of the other of the topsheet and the acquisition material, and the differing colors are visible when viewing a wearer-facing surface of the absorbent article.

Claims (18)

1. An absorbent article comprising:

a liquid permeable topsheet;

an absorbent core;

an acquisition material positioned between the topsheet and the absorbent core;

wherein the liquid permeable topsheet and the acquisition material form a three-dimensional material comprising:

a first surface facing the topsheet;

a second surface facing the absorbent core;

a generally planar first region; and

a plurality of discrete integral second regions that comprise deformations forming protrusions comprising fibers extending outwardly in a Z-direction and toward the absorbent core from the second surface of the three-dimensional material and openings in the first surface of the three-dimensional material, wherein at least some protrusions each comprise:

a base proximate to the second surface;

a distal end extending outwardly 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 said fibers surrounding the side walls and cap of the protrusions, wherein the side walls have interior surfaces, wherein the interior surfaces of the side walls define one of said openings in the first surface, wherein the cap has a portion with a maximum interior width, wherein the base opening has a width measured in the same direction as the maximum interior width, and wherein the maximum interior width of the cap of the protrusion is greater than the width of the base opening;

a liquid impermeable backsheet;

wherein said absorbent core is positioned at least partially intermediate the three-dimensional material and the liquid impermeable backsheet, wherein the absorbent core comprises an absorbent material at least partially surrounded by a core bag;

wherein each of the topsheet and the acquisition material comprises a nonwoven material; and

wherein any of the topsheet, core bag and the acquisition material comprises indicia that are visible when viewing a wearer-facing surface of the absorbent article.

2. The absorbent article of claim 1 , wherein the absorbent core comprises at least one channel disposed within the absorbent core that is substantially free of absorbent material.
