Abstract
Systems and methods for creating a grip surface (104) of a protectant glove (100). The method may comprise dipping a glove mold into a coagulant material (206); dipping the glove mold into a nitrile coating formulation to form an outer surface of the glove (208), wherein a biodegradable material is distributed throughout the nitrile coating formulation; vulcanizing at least the outer surface of the glove to form a protectant outer surface (212); 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 (216); and drying the glove to form a final glove comprising the grip surface (218).
