Abstract

Embodiments of a fluid absorption and distribution enhancement (FADE) product comprises at least one flow media layer, and at least one superabsorbent polymer layer.

Claims (30)

1. A fluid absorption and distribution enhancement (FADE) product comprising:

at least one flow media layer forming a flow network of pathways to convey a fluid disposed therein; and

at least one superabsorbent polymer layer oriented above or below the at least one flow media layer.

2. The FADE product of claim 1 where the FADE product is integrated into an absorption pad for use in the medical, pet, or food industries.

3. The FADE product of claim 1 where the FADE product is integrated into a medical dressing.

4. The FADE product of claim 1 where the FADE product is integrated into a diaper.

5. The FADE product of claim 1 where the FADE product is integrated into a hospital bed.

6. The FADE product of claim 1 where the FADE product is integrated into an ambulance cot.

7. The FADE product of claim 1 where the FADE product is integrated into a patient transport litter.

8. The FADE product of claim 1 further comprising one or more flow channels in the superabsorbent polymer layer.

9. The FADE product of claim 1 further comprising superabsorbent fiber material.

10. The FADE product of claim 1 further comprising at least two flow media layers in contact with one another.

11. The FADE product of claim 1 further comprising deionizing material or a deionizing coating.

12. The FADE product of claim 1 where the superabsorbent polymer layer comprises small slits configured to facilitate stretching.

13. The FADE product of claim 1 where the superabsorbent polymer layer comprises superabsorbent polymer impregnated into a stretchable fabric layer.

14. The FADE product of claim 1 where the FADE product comprises at least three flow media layers including an upper flow media layer, a middle flow media layer, and a lower flow media layer; and

at least two superabsorbent polymer layers comprising a first superabsorbent polymer layer disposed between the upper flow media layer and the middle flow media layer, and a second superabsorbent layer disposed between the middle flow media layer and the lower flow media layer,

wherein the first superabsorbent polymer layer, the second superabsorbent polymer layer, or both comprise one or more flow channels.

15. A fluid absorption and distribution enhancement (FADE) product comprising:

at least two flow media layers; and

at least one superabsorbent polymer layer comprising one or more flow channels sandwiched between the flow media layers;

wherein,

the flow media layers comprise woven material, non-woven material, pressed mesh, knitted mesh, scrim material, or combinations thereof formed from nylon, polypropylene, propylene ethylene copolymer, polyolefin, polyester, polyamide, polyvinyl chloride, polyurethane, or combinations thereof, and

the superabsorbent polymer layer comprises poly (sodium acrylate) homopolymer or copolymer, polyacrylamide copolymer, ethylene maleic anhydride copolymer, polyvinyl alcohol copolymers, polyethylene oxide, polyacrylonitrile copolymer, cross-linked carboxymethylcellulose, or combinations thereof.

16. The FADE product of claim 15 where the FADE product comprises at least three flow media layers including an upper flow media layer, a middle flow media layer, and a lower flow media layer; and

at least two superabsorbent polymer layers comprising a first superabsorbent polymer layer disposed between the upper flow media layer and the middle flow media layer, and a second superabsorbent layer disposed between the middle flow media layer and the lower flow media layer.

17. The FADE product of claim 15 further comprising deionizing material or a deionizing coating.

18. The FADE product of claim 15 where the superabsorbent polymer layer comprises small slits configured to facilitate stretching.

19. The FADE product of claim 15 where the superabsorbent polymer layer comprises superabsorbent polymer impregnated into a stretchable fabric layer.

20. The FADE product of claim 15 where the FADE product is integrated into an absorption pad for use in the medical, pet, or food industries.
