Abstract
There is described a method of manufacturing silicone rubber gloves with a non-blocking surface by repeatedly dipping a form in a solvent dispersion of uncured silicone rubber to build up a plurality of layers and then forming a layer of liquid droplets on the surface of the solvent-containing uncured rubber, thereby forming a textured surface as the solvent evaporates.
Claims4
In a method of manufacturing textured gloves by repeatedly dipping a glove form into a solvent dispersion of uncured silicone rubber to build up a plurality of layers thereon followed by drying and curing the silicone rubber layers to form a glove, the additional step , prior to curing the layers, of exposing the uncured solvent-containing surface of the last layer of silicone rubber to a wet atmosphere as the solvent evaporates until a fine non-coalescing layer of fluid particles has been deposited over the surface of the last layer, the atmosphere being chosen so that the fluid particles have the same or greater heat of vaporization than said solvent whereby a texturized surface effect is produced.
