Abstract
The present disclosure provides substrates and laminates for absorbent articles and absorbent articles comprising the substrates or laminates. The substrates and laminates may have three-dimensional elements, land areas, and increased permeability regions intermediate at least some of the land areas and at least some of the three-dimensional elements. The increased permeability regions may be positioned adjacent to the three-dimensional elements. The land areas may have a first basis weight and the increased permeability regions may have a second basis weight. The first basis weight may be greater than the second basis weight.
Claims20
An absorbent article comprising:
- a front waist region;
- a back waist region;
- a crotch region positioned intermediate the front waist region and the back waist region;
- a substrate;
- a liquid impermeable backsheet;
- an absorbent core disposed at least partially intermediate the substrate and the liquid impermeable backsheet;
- and
- a pair of back ears extending from the back waist region;
- wherein the substrate comprises a nonwoven material comprising:
- fibers;
- three-dimensional elements;
- land areas comprising the fibers and positioned in areas free of the three-dimensional elements;
- wherein, in the land areas, the nonwoven material has a first basis weight, according to the Micro-CT Test;
- increased permeability regions comprising the fibers and positioned adjacent to at least some of the three-dimensional elements and intermediate at least some of the three-dimensional elements and at least some of land areas;
- and
- wherein, in the increased permeability regions, the nonwoven material has a second basis weight in the range of 75% to 25% less than the first basis weight of the land areas, according to the Micro-CT Test.
An absorbent article comprising:
- a front waist region;
- a back waist region;
- a crotch region positioned intermediate the front waist region and the back waist region;
- a substrate;
- a liquid impermeable backsheet;
- an absorbent core disposed at least partially intermediate the substrate and the liquid impermeable backsheet;
- and
- a pair of back ears extending from the back waist region;
- wherein the substrate comprises a nonwoven material comprising:
- fibers;
- through-air bonds between at least some of the fibers, wherein the nonwoven material is free of calendar or point bonds;
- three-dimensional elements;
- land areas comprising the fibers and positioned in areas free of the three-dimensional elements;
- wherein, in the land areas, the nonwoven material has a first basis weight, according to the Micro-CT Test;
- increased permeability regions comprising the fibers and positioned adjacent to at least some of the three-dimensional elements;
- wherein the increased permeability regions have a second basis weight in the range of 75% to 25% less than the first basis weight of the land areas, according to the Micro-CT Test.
