Abstract
An elastomeric article includes a first surface and a second surface which is treated with a friction treatment. The elastomeric article can be a glove in which the first surface is an inner donning surface and the second surface is an outer grip surface. The friction treatment reduces friction on the grip surface of the gloves in order to make it easier to don a second glove on top of the grip surface of the gloves of the present invention. The gloves of the present invention may be used as a first pair of gloves in a double-gloving configuration to conform with safety protocols.
Claims19
An elastomeric article comprising:
- an article comprising a flexible layer of elastomeric nitrile rubber formed from a nitrile rubber emulsion, the article having a first surface and a second surface;
- wherein the first surface and the second surface are chlorinated, wherein chlorination of the first surface and chlorination of the second surface are accomplished with different chlorine solutions, wherein chlorination of the first surface is accomplished by dipping the first surface into a sodium hypochlorite solution followed by dipping the first surface into a tank of hydrochloric acid;
- wherein the second surface is treated with a friction treatment that reduces the level of friction of the second surface to improve the ease with which a second elastomeric article can slide on top of the second surface, wherein the friction treatment of the second surface comprises the chlorination of the second surface, wherein the second surface has a static coefficient of friction in a range from about 0.3 to about 0.9 or a dynamic coefficient of friction in a range from about 0.3 to about 1.
A process for making an elastomeric article, the process comprising steps of:
- coating a surface of a former with a coagulant solution;
- immersing the former into a nitrile rubber emulsion to form a layer of coagulated nitrile rubber on the former surface, the coagulated nitrile rubber forming an elastomeric article on the former, the elastomeric article having a first surface that is exposed from the former and a second surface contacting the former;
- chlorinating the first surface of the elastomeric article, wherein chlorinating the first surface comprises dipping the former containing the elastomeric article into a first solution of sodium hypochlorite, then transferring the former containing the elastomeric article to a tank containing a second solution of hydrochloric acid;
- curing the elastomeric article;
- removing the elastomeric article from the former and inverting the elastomeric article such that the chlorinated first surface of the elastomeric article becomes an interior surface of the elastomeric article;
- and
- subjecting the inverted elastomeric article to a friction treatment to reduce the friction of the second surface of the elastomeric article, wherein the second surface has a static coefficient of friction in a range from about 0.3 to about 0.9 or a dynamic coefficient of friction in a range from about 0.3 to about 1 wherein the friction treatment of the second surface comprises chlorination of the second surface.

A kit for double-gloving, the kit comprising:
- a first elastomeric glove formed from a flexible layer of elastomeric nitrile rubber formed from a nitrile rubber emulsion, the glove having a chlorinated first surface and a friction treated second surface, wherein the chlorination of the first surface and the friction treatment of the second surface are accomplished with different chlorine solutions, wherein chlorination of the first surface is accomplished by dipping the first surface into a sodium hypochlorite solution followed by dipping the first surface into a tank of hydrochloric acid;
- and
- a second elastomeric glove for donning on top of the first elastomeric glove;
- wherein the friction treatment of the second surface of the first elastomeric glove reduces the level of friction of the second surface to improve the ease with which the second elastomeric glove can slide on top of the second surface to don the second elastomeric glove on top of the first elastomeric glove, wherein the second surface has a static coefficient of friction in a range from about 03 to about 0.9 or a dynamic coefficient of friction in a range from about 0.3 to about 1 wherein the friction treatment of the second surface comprises chlorination of the second surface.
