Abstract
Provided is a method of producing a glove, the method including: (1) the step of immersing a glove forming mold in a liquid coagulant containing calcium ions so as to allow the coagulant to adhere to the glove forming mold; (2) the step of adjusting the pH to be 9 or higher using an ammonium compound or an amine compound and leaving a glove emulsion composition to stand with stirring; (3) the dipping step of immersing the glove forming mold, to which the coagulant has thus adhered in the step (1), in the glove emulsion composition; (4) the gelling step of leaving the glove forming mold, to which the glove emulsion composition has thus adhered, to stand at a temperature for a period that satisfy specific conditions; (5) the leaching step of removing impurities from a cured film precursor thus formed on the glove forming mold; (6) the beading step of, after the leaching step, winding the cuff portion of the resulting glove; (7) the precuring step of heating and drying the cured film precursor that has been subjected to the beading step; and (8) the curing step of heating the cured film precursor at a specific temperature for a specific period to obtain a cured film.
