Biological method for forming grip surface during glove manufacture

1. A method of forming a grip surface of a glove, the method comprising:

dipping a glove mold into a coagulant material;

dipping the glove mold into a nitrile coating formulation to form an outer surface of the glove, wherein a biodegradable material is distributed throughout the nitrile coating formulation;

vulcanizing at least the outer surface of the glove to form a protective outer surface;

washing at least the outer surface of the glove with an enzyme solution;

decomposing, by the enzyme solution, the biodegradable material that is distributed throughout the outer surface of the glove, thereby forming a grip surface of the glove comprising an open-cell structure within the outer surface; and

drying the glove to form a final glove comprising the grip surface.

2. The method of claim 1 , wherein vulcanizing at least the outer surface comprises forming open-cell walls around a plurality of particles of the biodegradable material, and wherein, after decomposing the biodegradable material, the open-cell walls remain to form the grip surface of the glove.

3. The method of claim 1 , further comprising dressing an inner glove onto the glove mold before dipping the glove mold into the coagulant material, wherein the inner glove forms an inner surface of the glove when worn by a user.

4. The method of claim 1 , further comprising removing the glove from the glove mold before washing at least the outer surface of the glove with the enzyme solution.

5. The method of claim 1 , wherein the coagulant material comprises approximately 98% solvent and approximately 2% calcium nitrate.

6. The method of claim 1 , further comprising heating the glove mold to approximately 50° C. before dipping into the coagulant material.

7. The method of claim 1 , wherein the nitrile coating formulation comprises between approximately 50-300 grams of a 33% starch dispersion in water.

8. The method of claim 1 , wherein the nitrile coating formulation comprises a ratio of nitrile emulsion to starch dispersion in water between approximately 20:1 and approximately 3:1.

9. The method of claim 8 , wherein vulcanizing at least the outer surface of the glove comprises vulcanizing the nitrile emulsion of the nitrile coating formulation.

10. The method of claim 1 , wherein the nitrile coating formulation comprises one or more of the following: approximately 1000 grams of nitrile emulsion, between approximately 50-300 grams of 33% starch dispersion in water, between approximately 1-10 grams of 50% sulfur dispersion in water, between approximately 1-10 grams of 50% Zinc Diethyl Dithiocarbamate (ZDEC) dispersion in water, and between approximately 5-30 grams of 50% Zinc Oxide (ZnO) dispersion in water.

11. A method of forming a protectant glove, the method comprising:

mixing a nitrile coating formulation comprising a nitrile emulsion and a plurality of biodegradable particles distributed throughout the nitrile emulsion;

dipping a glove mold into the nitrile coating formulation to form an outer surface of the glove;

vulcanizing at least the outer surface of the glove to form a grip surface;

forming open-cell walls via the vulcanized nitrile emulsion formed about the plurality of biodegradable particles;

washing at least the outer surface of the glove with an enzyme solution; and

decomposing, by the enzyme solution, the biodegradable particles that are distributed throughout the outer surface of the glove, thereby forming a grip surface comprising the open-cell walls of the nitrile emulsion of the outer surface.

12. The method of claim 11 , further comprising dipping the glove mold into a coagulant material before dipping the glove mold into the nitrile coating.

13. The method of claim 11 , further comprising drying the glove to form a final glove comprising the grip surface.

14. The method of claim 11 , wherein the enzyme solution comprises amylace.

15. The method of claim 11 , wherein dipping the glove mold comprises dipping at least the fingers and palm of the glove mold.
