Abstract

The present disclosure relates to absorbent articles comprising belts comprising one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or low decitex (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand Test in the Method below) under the elastics, while providing adequate modulus of (between about 2 gf/mm and 15 gf/mm), resulting in a Product Hip-to-Waist Silhouette from about 0.8 to about 1.1 and a Product Waist-to-Crotch Silhouette from about 0.8 to about 2.0 to provide for the advantages described above.

Claims18

Dependent claims

An absorbent article, comprising:

a front waist region, a back waist region, and a crotch region therebetween;
a chassis comprising a topsheet, a backsheet and an absorbent core disposed between the topsheet and the backsheet, wherein the chassis comprises a front end edge, a back end edge, and a pair of laterally opposing side edges;
a back belt disposed in the back waist region overlapping and extending outboard of the back end edge of the chassis to form a back waist edge;
a front belt disposed in the front waist region overlapping and extending outboard of the front end edge of the chassis to form a front waist edge;
wherein the front belt is joined to the back belt at or adjacent the laterally opposing belt side edges to form leg openings and a waist opening to form a closed-form pant;
a longitudinal axis extending from the midpoint of the front waist edge to the midpoint of the back waist edge;
a lateral axis extending perpendicular to the longitudinal axis through the midpoint of the longitudinal axis;
wherein the back belt comprises a first plurality of elastics comprising greater than about 40 elastic strands, and wherein the front belt comprises a second plurality of elastics comprising greater than about 40 elastic strands;
wherein the Pressure-Under-Strand of the first plurality of elastics is from about 0.1 to about 1 psi, and wherein the Pressure-Under-Strand of the second plurality of elastics is from about 0.1 to about 1 psi;
wherein the Product Hip-to-Waist Silhouette is from about 0.8 to about 1.1;
wherein the Product Waist-to-Crotch Silhouette is from about 0.8 to about 2.0;
and
wherein the absorbent article has a Relaxed Product Waist Width from about 80 mm to about 270 mm and a Relaxed Product Hip Width from about 80 mm to about 300 mm.
