Abstract

A disposable absorbent article having a crimped fiber spunbond nonwoven web is described herein. The disposable absorbent article has a topsheet, a backsheet attached to the topsheet, and an absorbent core disposed between the topsheet and the backsheet. The crimped fiber spunbond nonwoven web is either at least a portion of the topsheet or the backsheet or at least a portion of the topsheet and the backsheet. The crimped fiber spunbond nonwoven web includes a plurality of apertures extending therethrough.

First claim

What is claimed is:

1. A disposable absorbent article comprising:
a topsheet comprising a laminated structure comprising a crimped fiber spunbond nonwoven web and a spunbond nonwoven web, wherein the crimped fiber spunbond nonwoven web comprises a plurality of apertures extending therethrough, wherein the crimped fiber spunbond nonwoven web forms a portion of a wearer-facing surface of the disposable absorbent article, and wherein the crimped fiber spunbond nonwoven web comprises a hydrophobic treatment;
a backsheet attached to the topsheet; and
an absorbent core disposed between the topsheet and the backsheet.

2. The disposable absorbent article of claim 1 , wherein the crimped fiber spunbond nonwoven web comprises a plurality of out-of-plane deformations and wherein the crimped fiber spunbond nonwoven web comprises a plurality of calendar bonds forming a calendar bonded area of about 10 percent to about 18 percent.

3. The disposable absorbent article of claim 1 , wherein the disposable absorbent article comprises a first zone, second zone, and a third zone, wherein each of the first zone, second zone, and third zone, extend generally in a longitudinal direction, and wherein the third zone is disposed between the first zone and second zone, and wherein the plurality of apertures are disposed in the third zone.

4. The disposable absorbent article of claim 3 , wherein a portion of the plurality of apertures forms aperture indicia.

5. The disposable absorbent article of claim 3 , wherein the first zone and the second zone each comprise a plurality of out-of-plane deformations comprising at least one of ridges, grooves, caps, and tufts.

6. The disposable absorbent article of claim 5 , wherein the plurality out-of-plane deformations forms structural indicia.

7. The disposable absorbent article of claim 1 , further comprising a layer between the topsheet and the absorbent core, wherein the layer comprises at least one of a secondary topsheet, an acquisition layer, or distribution layer, and wherein a plurality of bond sites join the topsheet to the layer between the topsheet and the absorbent core.

8. The disposable absorbent article of claim 7 , wherein the plurality of bond sites form bond indicia visible from the topsheet.

9. The disposable absorbent article of claim 1 , wherein the plurality of apertures forms apertured indicia.

10. The disposable absorbent article of claim 1 , wherein the spunbond nonwoven web comprises a hydrophilic treatment.

11. The disposable absorbent article of claim 1 , wherein the spunbond nonwoven web comprises a hydrophobic treatment.

12. The disposable absorbent article of claim 1 , wherein the crimped fiber spunbond nonwoven web comprises a heterogeneous structure comprising at least a first plurality of continuous fibers and a second plurality of continuous fibers, wherein the first plurality of continuous fibers and the second plurality of continuous fibers are different.

13. The disposable absorbent article of claim 12 , wherein the first plurality of continuous fibers comprises a hydrophobic melt additive.

14. The disposable absorbent article of claim 13 , wherein the second plurality of continuous fibers comprises a hydrophilic melt additive.
