Abstract

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

What is claimed is:

1 . A nonwoven laminate structure comprising:
a first nonwoven web comprising continuous spunbond crimped fibers; a second web joined to the first nonwoven web, wherein a plurality of apertures extend through at least one of the first nonwoven web or the second web.

2 . The nonwoven laminate of claim 1 , wherein the second web comprises a film.

3 . The nonwoven laminate of claim 1 , wherein the plurality of apertures extend through the first nonwoven web.

4 . The nonwoven laminate of claim 3 , wherein the plurality of apertures extend through the second web.

5 . The nonwoven laminate of claim 1 , wherein the continuous spunbond crimped fibers comprise two different polypropylene polymers configured in at least one of a side-by-side configuration or a core-sheath configuration.

6 . The nonwoven laminate of claim 1 , wherein the first nonwoven web comprises an additive for softness.

7 . The nonwoven laminate of claim 1 , wherein the first nonwoven web comprises a hydrophilic additive.

8 . The nonwoven laminate of claim 1 , wherein the first nonwoven web comprises a hydrophobic additive.

9 . The nonwoven laminate of claim 1 , wherein the plurality of apertures form apertured indicia.

10 . The nonwoven laminate of claim 1 , wherein the first nonwoven web is calendar bonded between about 10 percent to about 18 percent.

11 . The nonwoven laminate of claim 1 , wherein the first nonwoven web forms a portion of a wearer-facing surface of a disposable absorbent article.

12 . The nonwoven laminate of claim 1 , wherein the first nonwoven web forms a portion of a garment-facing surface of a disposable absorbent article.

13 . The nonwoven laminate of claim 1 , wherein the laminate forms a portion of at least one of an outer cover, a leg cuff, an ear, a side panel, a fastener, a waist band, or a belt of a disposable absorbent article.

14 . The nonwoven laminate of claim 1 , wherein a melt lip defines at least a portion of a perimeter of the plurality of apertures.

15 . A nonwoven web comprising:
a plurality of continuous spunbond crimped fibers, wherein a plurality of apertures extend through the nonwoven web.

16 . The nonwoven web of claim 15 , wherein the continuous spunbond crimped fibers comprise two different polypropylene polymers configured in at least one of a side-by-side configuration or a core-sheath configuration.

17 . The nonwoven web of claim 15 , further comprising an additive for softness.

18 . The nonwoven web of claim 15 , further comprising a hydrophilic additive.

19 . The nonwoven web of claim 15 , further comprising a hydrophobic additive.

20 . The nonwoven web of claim 15 , wherein the plurality of apertures form apertured indicia.

21 . The nonwoven web of claim 15 , wherein the nonwoven web is calendar bonded between about 10 percent to about 18 percent.

22 . The nonwoven web of claim 15 , wherein the nonwoven web forms a portion of a wearer-facing surface of a disposable absorbent article.

23 . The nonwoven web of claim 15 , wherein the nonwoven web forms a portion of a garment-facing surface of a disposable absorbent article.

24 . The nonwoven web of claim 15 , wherein a melt lip defines at least a portion of a perimeter of the plurality of apertures.
