Abstract
An absorbent article for menstrual and/or incontinence purposes, having a unique two-layer acquisition and absorbent structure. The cover layer includes a nonwoven material. The absorbent core includes multiple strata including super absorbent, fiber material that is pulp and/or bicomponent fibers, and a binder material. The total thickness of the absorbent article is less than or equal to the thickness of absorbent articles of similar absorbent characteristics. The absorbent article includes various absorbent properties that are improved despite parity or reduction in overall thickness.
Claims18
An absorbent article having a length, a width, and a thickness, comprising:
- a cover layer having a body facing surface and a lower cover surface opposite to the body facing surface;
- and
- an absorbent core adjacent to the lower cover surface, the absorbent core having a basis weight of 110 gsm to 170 gsm, the absorbent core comprising:
- a first strata having a first fiber material having at least one of a pulp material and a bicomponent fiber material;
- a second strata having super absorbent polymer and a second fiber material having the pulp material and the bicomponent fiber material;
- a third strata having a third fiber material having at least one of the pulp material and the bicomponent fiber material;
- and
- a backsheet layer having a backsheet upper surface and a garment-facing surface opposite the backsheet upper surface;
- wherein the absorbent article has a modified circular bend of between about 130 g and about 230 g;
- wherein the absorbent article has an absorbent capacity of between about 11 g and about 27 g;
- wherein the first fiber material, the second fiber material, and the third fiber material are substantially the same;
- wherein a ratio of the super absorbent polymer and the second fiber material is between about 1.5:1 and about 4:1;
- wherein the super absorbent polymer is only within the second strata;
- and
- wherein the thickness of the absorbent article is between about 1.1 mm and about 2.2 mm.
