Abstract

An absorbent mixture consisting of an absorbent such as sodium or potassium polyacrylate, a fluent wax and a channeling agent. A product consisting of a porous member containing a mixture including an absorbent such as sodium or potassium polyacrylate, a fluent wax and a channeling agent.

Claims (21)

1. A liquid water absorbing form comprising:

a paste or solid wax;

a superabsorbent encapsulated in the wax; and

a channeling agent in the wax wherein the channeling agent conducts liquid water through the wax to the superabsorbent but does not conduct water vapor to the superabsorbent.

2. A liquid water absorbing form as set forth in claim 1 wherein said wax is selected from the group consisting of petroleum based, animal, vegetable, and synthetic waxes.

3. A liquid water absorbing form as set forth in claim 1 wherein said channeling agent is selected from the group consisting of microcrystalline cellulose, gums, alginates, and starches.

4. A liquid water absorbing form as set forth in claim 1 wherein said superabsorbent is selected from the group consisting of sodium polyacrylate and potassium polyacrylate.

5. A liquid water absorbing form as set forth in claim 4 wherein said superabsorbent is present by weight in the amount of between about 5% and 90%, and wherein said wax is present by weight in the amount of between 10% and 85%, and wherein the channeling agent is present by weight in an amount of between about 2% and 40%.

6. A liquid water absorbing form as set forth in claim 5 wherein said superabsorbent is present by weight in the amount of between about 15% and 60%, and wherein said wax is present by weight in the amount of between 50% and 75%, and wherein said channeling agent is present by weight in an amount of between about 8% and 25%.

7. A liquid water absorbing form as set forth in claim 6 wherein said superabsorbent is present by weight in the amount of between about 21% and 25%, and wherein said wax is present by weight in the amount of between 60% and 65%, and wherein said channeling agent is present by weight in an amount of between 12% and 14%.

8. A product comprising a porous member containing a liquid water absorbing form comprising:

a wax encapsulating a superabsorbent and containing a channeling agent, wherein the channeling agent conducts liquid water through the wax to the superabsorbent, but does not conduct water vapor to the superabsorbent.

9. A product as set forth in claim 8 wherein said wax is selected from the group consisting of petroleum-based, animal, vegetable and synthetic waxes.

10. A product as set forth in claim 8 wherein said channeling agent is selected from the group consisting of microcrystalline cellulose, gums, alginates and starches.

11. A product as set forth in claim 8 wherein said superabsorbent is selected from the group consisting of sodium polyacrylate and potassium polyacrylates.

12. A product as set forth in claim 8 wherein said superabsorbent is present by weight in the amount of between about 5% and 90%, and wherein said wax is present by weight in the amount of between 10% and 85%, and wherein said channeling agent is present by weight in an amount of between about 2% and 40%.

13. A product as set forth in claim 8 wherein said porous member is a string.

14. A product as set forth in claim 8 wherein said porous member is a form which has been fabricated from a sheet.

15. A product as set forth in claim 8 wherein said superabsorbent is present by weight in the amount of between about 15% and 60%, and wherein said wax is present by weight in the amount of between 50% and 75%, and wherein said channeling agent is present by weight in an amount of between about 8% and 25%.

16. A product as set forth in claim 12 wherein said superabsorbent is present by weight in the amount of between about 21% and 25%, and wherein said wax is present by weight in the amount of between 60% and 65%, and wherein said channeling agent is present by weight in an amount of between about 12% and 14%.

17. A liquid water absorbing form as set forth in claim 1 , wherein the channeling agent in the wax provides a plurality of channels and wherein at least one of the plurality of channels comprises a micro channel.
