Abstract
The present invention is an absorbent core that may be incorporated into absorbent hygiene articles, such as baby diapers, adult incontinence or feminine hygiene articles. It is particularly suited for articles which are intended to receive more than one liquid gush load, as the absorbent core comprises a fluid distribution layer that comprises sub-layers comprising particular ratios of multicomponent binder fibers, cross-linked cellulose fiber and/or treated or untreated cellulosic fibers.
Claims13
A hygiene article, comprising:
- a liquid permeable topsheet;
- a liquid impermeable backsheet;
- and
- an absorbent core located between the liquid permeable topsheet and the liquid impermeable backsheet, the absorbent core comprising
- a) a fluid distribution layer, the fluid distribution layer being formed of two or more sub-layers comprising:
- a first sub-layer, wherein the first sub-layer comprises a first amount of multiple component binder fibers or cross linked cellulose fibers, or a combination thereof, and a second and/or subsequent sub-layer, wherein the second and/or subsequent sub-layer comprises treated or untreated pulp and a second amount of multiple component binder fibers, cross linked cellulose fibers, or a combination thereof, wherein the % by weight of the first sub-layer of the first amount of multicomponent binder fibers and/or cross linked cellulose fibers is greater than the % by weight of the second and/or subsequent sub-layers of the second amount of multicomponent binder fibers and/or cross linked cellulose fibers;
- and
- b) a fluid storage layer, wherein the fluid storage layer comprises at least 50% by weight of the fluid storage layer of a super absorbent polymer,
- wherein said first sub-layer of said distribution layer is for being positioned towards a wearer during its intended use,
- wherein said second and/or subsequent sub-layer is positioned such that is further away from a wearer during its intended use than said first sub-layer, and
- wherein said fluid storage layer is positioned such that that is further away from a wearer during its intended use than said second sub-layer.
