Recycled cellulosic industrial and commercial absorbent matting
View Patent ↗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.
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.
