Abstract

A textured laminate structure and absorbent articles having a component formed of the textured laminate structure are disclosed. The textured laminate structure may have a first layer formed of a nonwoven web having a preexisting pattern of first apertures therethrough, a second layer, and one or more elastic members disposed between the first and second layers in a prestrained condition. The laminate structure may be discontinuously joined or bonded such that the first layer is joined or bonded to the structure in first portions and unjoined or unbonded to the structure in second portions. The structure provides a stretch laminate with tactilely and visually interesting features, and may be used to form components of a disposable absorbent article such as a side panel thereof.

First claim

What is claimed is:

1. A textured laminate structure, comprising:
a first layer formed of a first nonwoven web having a machine direction, the first nonwoven web being formed of polymeric fibers having a machine direction bias and having a pattern of pre-bonds thereon, and a first preexisting pattern of first apertures therethrough;
a second layer; and
a plurality of spaced apart strands of elastomeric material oriented along the machine direction, disposed between the first layer and the second layer and bonded therebetween, the strands of elastomeric material having been disposed between the first and second layers in a pre-strained condition, thereby forming a pattern of rugosities extending in the z-direction present in at least the first layer when the laminate is in a relaxed condition,
wherein the laminate structure is discontinuously joined or bonded such that the first layer is joined or bonded to the structure in first portions of the first layer and unjoined or unbonded to the structure in second portions of the first layer.

2. The laminate structure of claim 1 , wherein the rugosities have a machine direction spacing and a cross direction spacing, and the first apertures have a machine direction spacing and a cross direction spacing, and either or both of the following relationships exist in at least a portion of the laminate structure:
a) the machine direction rugosity spacing is a substantially even divisor or substantially even multiple of the machine direction first aperture spacing;
b) the cross direction rugosity spacing is a substantially even divisor or substantially even multiple of the cross direction first aperture spacing.

3. The laminate structure of claim 1 , wherein the strands have a cross direction spacing, and the first apertures have a cross direction spacing, and the cross direction strand spacing is a substantially even divisor or substantially even multiple of the cross direction first aperture spacing.

4. The laminate structure of claim 1 , wherein the rugosities have a machine direction spacing, and the first apertures have a machine direction spacing, and the machine direction rugosity spacing is a substantially even divisor or substantially even multiple of the machine direction first aperture spacing.

5. The laminate structure of claim 1 wherein the pre-existing pattern of first apertures is substantially similar to the pattern of pre-bonds in one or more of: machine-direction spacing, cross-direction spacing, aperture shape and aperture size.

6. The laminate structure of claim 1 wherein the second layer is formed of a second nonwoven web.

7. The laminate structure of claim 6 wherein the second nonwoven web has a second preexisting pattern of second apertures therethrough.

8. The laminate structure of claim 1 wherein a majority of the first apertures define shapes whose greatest dimension is oriented along the machine direction.

9. The laminate structure of claim 1 wherein the first apertures define shapes selected from the group consisting of rod-shaped, arc-shaped, other curved finite paths, oval, elliptical or polygon, and any combinations thereof.

10. The laminate structure of claim 1 wherein the first apertures are defined by edges at which the material of the fibers is thermally fused, or deformed and entangled.

11. The laminate structure of claim 1 wherein one of the first or second layers is tinted, pigmented or printed in a first color that visually contrasts with a second color of the other of the first or second layers.

12. The laminate structure of claim 1 wherein the first nonwoven web comprises spunbond fibers formed of polyolefin.

13. The laminate structure of claim 1 wherein the first nonwoven web is a carded material comprising staple fibers.

14. The laminate structure of claim 1 wherein the first layer is bonded to the structure by a pattern of adhesive disposed between the first layer and the second layer.

15. The laminate structure of claim 1 wherein the first layer is bonded to the structure by a pattern of thermal or compression bonds between the first layer and the second layer.

16. The laminate structure of claim 1 wherein the rugosities have peaks, and at least some of the first apertures are present on the peaks.

17. A disposable absorbent article in the form of a pant or diaper having a front waist region ending at a front waist edge, a rear waist region ending at a rear waist edge, the waist edges defining a lateral direction, wherein the laminate structure of claim 1 forms a panel interconnecting the front and rear waist regions.

18. The disposable absorbent article of claim 17 wherein the machine direction is substantially parallel with the lateral direction.
