Textured gloves
Provided among other things is a glove formed by latex dipping having one or more textured finger tips wherein: the texture at the finger tips results from forming the glove on a former having the following properties: (micrometer) Ra Av. roughness about 7-14 Rsm Mean width of roughness about 500-720 Rpc Peak count about 15-20 the glove being non-chlorinated, wherein the glove is a (i) single dip nitrile glove or (ii) a dipped glove with a textured layer formed of polymer latex, and comprising a multivalent metal ion salt of an organic acid with log P of about 4 to about 15.
1. A method of forming a glove comprising:
coating a glove former with coagulant;
applying a coagulable elastomer formulation to the coagulant coated former so that the former is coated with coagulated elastomer; and
curing the elastomer coating, wherein a grip-defining portion of the former has the following properties:
(micrometer)

and
forming a the glove with a grip portion corresponding to the grip-defining portion of the former, with the glove thereby having texture molded by the grip-defining portion of the former,
wherein the glove formed is a (i) single dip nitrile glove or (ii) a dipped glove with a so textured layer formed of natural rubber latex or synthetic rubber latex, and comprising a multivalent metal ion salt of an organic acid, the organic acid with log P of about 4 to about 15.
