  • Method for producing a rubber glove
    Patent number: 6527990
    Abstract: A rubber glove is produced by sequentially performing the step of immersing a glove mold in a coagulating synthetic rubber latex containing synthetic rubber in latex form, thermally expansible microcapsules, and a rubber coagulant to form a coagulant-containing synthetic rubber film on the surface of the glove mold; the step of immersing the glove mold in rubber-incorporating latex to form a gelled rubber layer; the step of heating a rubber laminate composed of the synthetic rubber film and the gelled rubber layer to vulcanize the rubber laminate; and the step of turning the vulcanized rubber laminate inside out, and removing it from the glove mold. This method produces a rubber glove, which is excellent in anti-blocking properties and grip under dry or wet conditions, by a simple procedure and for a low cost.
