Abstract

Gloves having a foamed polymeric, elastomeric, or latex foam layer disposed on a non-foamed polymeric, elastomeric, or latex structural or liquid resistant layer are disclosed.

First claim

The invention claimed is:

1. A cured absorbent composite glove comprising:
a structural layer comprising a non-foamed polymer material; and
a liquid absorbent layer affixed to the liquid resistant layer, which is formed of a foamed polymeric material, includes open cells for sweat management, has a thickness of about 1 to about 5 mil, and has a water absorption due to the open cells of 0.10 g/dm 2 or higher.

2. The cured absorbent composite glove of claim 1 , packaged with the liquid absorbent layer configured to provide the inside surface.

3. The glove of claim 1 , wherein the structural layer and absorbent layer comprise a same polymer material.

4. The glove of claim 3 , wherein the structural layer and absorbent layer comprise nitrile.

5. The glove of claim 1 , wherein the polymer material of the structural and absorbent layers comprise natural latex, guayule, polyisoprene, synthetic latexes, nitrile, nitrile-butadiene rubber, butadiene, non-carboxylated acrylonitrile butadiene, carboxylated acrylonitrile butadiene, butyl latex, polychloroprene, polyurethane, styrene-butadiene, acrylonitrile-butadiene, or blends thereof.

6. The glove of claim 2 , wherein the thickness of the structural layer ranges from about 0.004 to 0.005 inches, the thickness of the absorbent layer ranges from about 0.001 to about 0.004 inches, and the absorbent layer has a water absorption of 0.12 g/dm 2 or higher.

7. The glove of claim 6 , wherein the thickness of the absorbent layer ranges from about 0.001 to about 0.002 inches.

8. A method of forming an article, comprising:
disposing a coagulant on a former;
applying a non-foamed elastomeric material on the former, forming a non-foamed layer;
applying a foamed elastomeric material on the non-foamed layer, forming a foamed coating on the non-foamed layer;
leaching the foamed layer to remove 10% or more but not all of the initial foamed layer; and
curing the non-foamed layer and the remaining foamed layer, to form the article, the foamed layer of the article having a thickness of about 1 to about 5 mil and water absorption of 0.10 g/dm 2 or higher.

9. The method of claim 8 , wherein the article is wearable with the water absorbent layer interior, and further comprising the step of packaging the article with the liquid absorbent layer configured so that the article can be donned without inverting it.

10. The method of claim 8 , further comprising the step of applying a coagulant to the non-foamed layer following the applying a non-foamed elastomeric material step.

11. The method of claim 8 , wherein the foamed elastomeric material has a viscosity from about 400 to about 800 centipoise at 25-35° C.

12. The method of claim 11 , wherein the foamed elastomeric material has a viscosity from about 500 to about 600 centipoise at 30° C.

13. The method of claim 8 , wherein the foamed elastomeric material has an air content from about 50% to about 70%.

14. The method of claim 8 , wherein the foamed elastomeric material comprises about 0.2 to about 3 phr of thixotropic filler.

15. The method of claim 8 , wherein the foamed elastomeric material comprises about 0.3 to about 1 phr of thixotropic filler.

16. The method of claim 8 , wherein curing comprises heating to approximately 100° C. to 150° C. for approximately 10 to 60 minutes.

17. The method of claim 8 , wherein curing comprises heating to approximately 120° C. to 140° C. for approximately 12 to 40 minutes.

18. The method of claim 8 , wherein leaching comprises removing 20% or more but not all of the initial foamed layer.

19. The method of claim 8 , wherein leaching comprises removing 30% or more but not all of the initial foamed layer.

20. The method of claim 8 , wherein the foamed layer has water absorption of 0.14 g/dm 2 or higher.

21. The glove of claim 2 , wherein the thickness of the structural layer ranges from about 0.004 to 0.005 inches, the thickness of the absorbent layer ranges from about 0.001 to about 0.004 inches, and the absorbent layer has a water absorption of 0.14 g/dm 2 or higher.

22. The glove of claim 21 , wherein the thickness of the absorbent layer ranges from about 0.001 to about 0.002 inches.
