Patent number: 12171292Abstract: A method for producing a supporting glove includes the steps of applying a specific amount of a first polymer mixed liquid to a knitted glove; drying the first polymer mixed liquid applied to the knitted glove; applying a coagulant solution to the knitted glove after drying; applying a specific amount of a second polymer mixed liquid to the knitted glove after applying the coagulant solution; and drying the second polymer mixed liquid applied to the knitted glove. A first polymer film is formed to cover a yarn knitted into the knitted glove over the entire thickness direction of at least the part of the knitted glove. A second polymer film is formed to continuously cover the first polymer film to form at least a part of an outer surface and not reaching an inner surface of the knitted glove.Type: GrantFiled: June 2, 2023Date of Patent: December 24, 2024Assignee: SHOWA GLOVE CO.Inventor: Hidetoshi Kishihara
