Abstract

Official abstract text for this publication.

Nonwoven webs/nonwoven laminates for use in absorbent articles are disclosed. The nonwoven laminate includes a first nonwoven web with continuous spunbond crimped fibers and a second web joined to the first nonwoven web. A plurality of apertures extend through at least one of the first nonwoven web or the second web. The nonwoven web includes a plurality of continuous spunbond crimped fibers wherein a plurality of apertures extend through the nonwoven web.

First claim

Opening claim text (preview).

What is claimed is: 1. An article comprising: a chassis having a topsheet, backsheet and an absorbent core disposed between the topsheet and backsheet; and an elastic ear comprising: a first layer comprising a nonwoven web, and a second layer comprising a film; wherein the first layer and the second layer are joined together by ultrasonic bonding; wherein the first layer comprises a first plurality of apertures, and a portion of the second layer is exposed through at least one of the first plurality of apertures; and wherein the second layer comprises a second plurality of apertures, and a portion of the first layer is exposed through at least one of the second plurality of apertures. 2. The article of claim 1 wherein the nonwoven web comprises a crimped fiber spunbond nonwoven web. 3. The article of claim 2 wherein the crimped fiber spunbond nonwoven web comprises fibers having two different polypropylene polymers configured in a side-by-side configuration. 4. The article of claim 1 wherein the first plurality of apertures is disposed in a pattern. 5. The article of claim 1 comprising an additional layer comprising continuous spunbond crimped fibers. 6. The article of claim 1 wherein the first layer comprises a meltblown web. 7. The article of claim 1 wherein the first layer comprises a SMS construction. 8. The article of claim 1 wherein the elastic ear is disposed in the rear waist region. 9. The article of claim 1 further comprising a fastening system joined to the elastic ear. 10. The article of claim 1 wherein the elastic ear is integral with the chassis. 11. The article of claim 1 wherein the elastic ear is a separate component from the chassis. 12. The article of claim 2 wherein the crimped fiber spunbond nonwoven web is located on a garment-facing surface of the elastic ear.
