Abstract

Claims (38)

1 . An absorbent article comprising:

a front waist region, a rear waist region and a crotch region disposed between the front waist region and the rear waist region;

a topsheet, a backsheet and an absorbent core disposed between the topsheet and the backsheet; and

a stretch laminate comprising a bonding region comprising a plurality of ultrasonic bonds, wherein each of the plurality of ultrasonic bonds comprises a major dimension and a minor dimension, wherein a majority of the ultrasonic bonds are oriented in a stretch direction such that the major dimension is parallel to a stretch direction, and wherein each ultrasonic bond in the plurality comprises at least one dimension that is 0.7 mm or greater;

wherein the bonding region comprises a Hysteresis Ratio of 2.5 or less and an Unload Force at 50% of 0.44 MPa or greater.

2 . The absorbent article of claim 1 wherein the bonding region comprises a Hysteresis Ratio of 2.4 or less.

3 . The absorbent article of claim 1 wherein the stretch laminate comprises a Bond Density of at least 1.5%.

4 . The absorbent article of claim 1 wherein a majority of the stretch direction oriented bonds comprise an aspect ratio of at least 1.25.

5 . The absorbent article of claim 1 wherein the stretch laminate comprises one or more reinforcing features, wherein the reinforcing features are selected from the group consisting of additional bonds, layers, folds, substrates and combinations thereof.

6 . The absorbent article of claim 1 wherein the stretch laminate is disposed in a component selected from the group consisting of an ear, a waistband, a belt and combinations thereof.

7 . An absorbent article comprising:

a first waist region, a second waist region and a crotch region disposed between the first and second waist regions;

a topsheet, a backsheet and an absorbent core disposed between the topsheet and the backsheet; and

a stretch laminate, wherein the stretch laminate comprises:

a first bonding region having a first plurality of ultrasonic bonds, wherein each bond in the first plurality comprises a major dimension and a minor dimension and are oriented such that the major dimension is substantially parallel to a stretch direction; and

a second bonding region having a second plurality of bonds, wherein the majority of bonds in the second plurality are oriented in a second direction, the second direction being substantially perpendicular to the stretch direction,

wherein the second bonding region comprises a Low Stress Region, and

wherein a total bond area of the first plurality of ultrasonic bonds is greater than a total bond area of the second plurality of bonds.

8 . The absorbent article of claim 7 wherein the Low Stress Region comprises a Load Force at 50% of about 1.46 MPa or less.

9 . The absorbent article of claim 7 wherein the second plurality is at least partially interspersed or overlapping relationship with the first plurality.

10 . The absorbent article of claim 7 wherein the stretch laminate comprises a Bond Density of at least 1.5%.

11 . The absorbent article of claim 7 wherein at least some of the stretch direction oriented bonds comprise an aspect ratio of at least 1.25.

12 . The absorbent article of claim 7 wherein the stretch laminate comprises one or more reinforcing features, wherein the reinforcing features are selected from the group consisting of additional bonds, layers, folds, substrates and combinations thereof.

13 . The absorbent article of claim 7 wherein the second plurality of bonds comprises a plurality of ultrasonic bonds.

14 . An absorbent article comprising:

a first waist region, a second waist region and a crotch region disposed between the first and second waist regions;

a topsheet, a backsheet and an absorbent core disposed between the topsheet and the backsheet; and

a stretch laminate, the stretch laminate comprising:

a nonwoven layer and a film;

a bonding region having a plurality of ultrasonic bonds, wherein each of the plurality of ultrasonic bonds comprises a major dimension and a minor dimension, wherein a majority of the plurality of ultrasonic bonds are oriented in a stretch direction such that the major dimension is parallel to a stretch direction, and wherein each of the plurality of ultrasonic bonds comprise an aspect ratio of at least about 1.25;

a 10-Hour Force Drop of 65% or less, and

a Growth in Aperture of 50% or less.

15 . The absorbent article of claim 14 wherein each of the ultrasonic bonds oriented in the stretch direction comprise an elliptical shape.

16 . The absorbent article of claim 14 wherein the laminate comprises a Hysteresis Ratio of 2.4 or less.

17 . The absorbent article of claim 14 wherein the bonding region further comprises one or more bonds oriented in a second direction, the second direction being perpendicular to the stretch direction.

18 . The absorbent article of claim 17 wherein each of the bonds oriented in the second direction comprises a major dimension length of 1.2 mm or less.

19 . The absorbent article of claim 17 wherein the bonding region comprises at least 25% of bonds oriented in the second direction.

20 . The absorbent article of claim 14 wherein the stretch laminate comprises one or more reinforcing features, wherein the reinforcing features are selected from the group consisting of additional bonds, layers, folds, substrates and combinations thereof.
