Abstract
Herein is disclosed a biodegradable absorbent article having a natural fiber cake which may include a mixture of plant fibers and plant pulp, such as from a banana plant, and in embodiments, includes an absorbent article having a permeable top sheet; a natural fiber cake that may be derived from plant material such as the banana plant; a water-insoluble back sheet; and an optional superabsorbent polymer, and wherein the absorbent article may be used for many purposes such as a sanitary napkin or urinary incontinence pads.
Claims28
A biodegradable absorbent article, comprising:
- a natural fiber cake comprising a superabsorbent polymer and cellulosic material containing plant pulp and plant fibers, wherein the superabsorbent polymer comprises a plant-derived compostable material, wherein said plant fibers are derived from at least the banana plant, and the plant pulp comprises pulped plant fibers derived from at least the banana plant, wherein the natural fiber cake contains substantially no wood pulp;
- a permeable top sheet covering one side of the natural fiber cake;
- and
- a water-insoluble back sheet covering an opposite side of the natural fiber cake, wherein said water-insoluble back sheet comprises a bio-based material,
- wherein the natural fiber cake, the permeable top sheet, and the water-insoluble back sheet are compostable.
A biodegradable absorbent article, comprising:
- a natural fiber cake comprising a superabsorbent polymer and cellulosic material containing plant pulp and plant fibers, wherein the superabsorbent polymer comprises a plant-derived compostable material, wherein said plant fibers are derived from at least hemp, and the plant pulp comprises pulped plant fibers derived from at least hemp, wherein the natural fiber cake contains substantially no wood pulp;
- a permeable top sheet covering one side of the natural fiber cake;
- and
- a water-insoluble back sheet covering an opposite side of the natural fiber cake, wherein said water-insoluble back sheet comprises a bio-based material,
- wherein the natural fiber cake, the permeable top sheet, and the water-insoluble back sheet are compostable.
A biodegradable absorbent article, comprising:
- a natural fiber cake comprising a superabsorbent polymer and cellulosic material containing plant pulp and plant fibers, wherein the superabsorbent polymer comprises a plant-derived compostable material, wherein said plant fibers are derived from at least kenaf, and the plant pulp comprises pulped plant fibers derived from at least kenaf, wherein the natural fiber cake contains substantially no wood pulp;
- a permeable top sheet covering one side of the natural fiber cake;
- and
- a water-insoluble back sheet covering an opposite side of the natural fiber cake, wherein said water-insoluble back sheet comprises a bio-based material,
- wherein the natural fiber cake, the permeable top sheet, and the water-insoluble back sheet are compostable.
