Abstract
An absorbent article includes a first waist region, a second waist region and a crotch region disposed between the first and second waist regions; and a topsheet, a backsheet and an absorbent core disposed between the topsheet and the backsheet. The article further includes a stretch laminate having a bonding region. The bonding region has a plurality of ultrasonic bonds, a majority of the ultrasonic bonds are oriented in a stretch direction, and the bonding region has a Hysteresis Ratio of 2.5 or less and an Unload Force at 50% of 0.44 MPa or greater.
Claims20
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.
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.
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.
