Abstract

An absorbent structure is provided which comprises a first outer layer, a second outer layer, a core layer positioned between the first outer layer and the second outer layer, wherein the core layer comprises a recycled cellulose material, and a core bonding agent.

Claims (26)

1. An absorbent structure comprising:

a first outer layer;

a second outer layer; and

a core layer positioned between the first outer layer and the second outer layer, wherein the core layer comprises:

a recycled material comprising cellulose and a polymer; and

a core bonding agent, wherein the polymer of the recycled material has a melting temperature above a melting temperature of the core bonding agent.

2. The absorbent structure of claim 1 , wherein the first outer layer comprises a first recycled cellulose material and a first bonding agent.

3. The absorbent structure of claim 2 , wherein the second outer layer comprises a second recycled cellulose material and a second bonding agent.

4. The absorbent structure of claim 1 , wherein the core bonding agent is heat fusible.

5. The absorbent structure of claim 1 , wherein the core bonding agent includes one or more of homofibers, multi-component fibers, powders made of amorphous polyester, polyethylene, and/or polypropylene.

6. The absorbent structure of claim 1 , wherein the recycled cellulose material is cellulose lost in industrial production.

7. The absorbent structure of claim 1 , wherein the recycled cellulose material is a post consumer cellulosic waste stream.

8. The absorbent structure of claim 3 , wherein the first and second recycled cellulose material is cellulose lost in industrial production.

9. The absorbent structure of claim 3 , wherein the first and second recycled cellulose material is a post consumer cellulosic waste stream.

10. The absorbent structure of claim 1 , wherein the first and second outer layers include a fire retardant material.

11. The absorbent structure of claim 1 , wherein the core layer includes a fire retardant material.

12. The absorbent structure of claim 1 , wherein the first and second outer layers include a colorant material.

13. The absorbent structure of claim 1 , wherein the core layer includes a colorant material.

14. The absorbent structure of claim 3 , wherein the first and second bonding agents are heat fusible.

15. The absorbent structure of claim 3 , wherein the first and second bonding agents each includes one or more of homofibers, multi-component fibers, powders made of amorphous polyester, polyethylene, and/or polypropylene.

16. The absorbent structure of claim 14 , wherein the first and second outer layers include more of the heat fusible bonding agent than the core layer.

17. The absorbent structure of claim 1 , wherein the first and second outer layers include a hydrophobic agent.

18. The absorbent structure of claim 1 , wherein the core layer includes a hydrophobic agent.

19. The absorbent structure of claim 1 , wherein the first and second outer layers include a hydrophilic surfactant.

20. The absorbent structure of claim 1 , wherein the core layer includes a hydrophilic surfactant.

21. The absorbent structure of claim 1 , wherein the core layer includes material refiberized from the entire absorbent structure.
