Abstract
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.
Claims20
A glove formed by latex dipping having one or more textured finger tips wherein:
- the texture at one or more finger tips results from forming the glove on a former having the following corresponding surface properties:
- (micrometer)
- Ra
- Av. roughness
- about 7-14
- Rsm
- Mean width of roughness
- about 500-720
- Rpc
- Peak count
- about 15-20;
- and
- the glove being non-chlorinated, wherein the glove is a (i) single dip nitrile glove or (ii) a dipped glove with a so 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.
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 former has the following properties:
- (micrometer)
- Ra
- Av. roughness
- about 7-14
- Rsm
- Mean width of roughness
- about 500-720
- Rpc
- Peak count
- about 15-20
- and, 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 rubber latex, and comprising a multivalent metal ion salt of an organic acid with log P of about 4 to about 15.
A glove former having one or more surfaces on finger tip regions with the following properties:
- (micrometer)
- Ra
- Av. roughness
- about 7-14
- Rsm
- Mean width of roughness
- about 500-720
- Rpc
- Peak count
- about 15-20.
