Glove having improved donning characteristics
View Patent ↗An elastomeric article includes a substrate body formed from an elastomeric material. The substrate body has a first surface, and a donning layer overlying at least a portion of the first surface. The donning layer is formed from a modified vinyl acetate polymer.
1. An elastomeric article comprising:
a substrate body comprising an elastomeric material, the substrate body having a first surface;
a donning layer overlying at least a portion of the first surface, the donning layer comprising a silicone-modified vinyl acetate polymer, containing from about 10 atomic % to about 30 atomic % silicon; and
a lubricant layer overlying at least a portion of the donning layer.
2. The article of claim 1 , wherein the elastomeric material comprises natural rubber.
3. The article of claim 1 , wherein the elastomeric material comprises a nitrile butadiene rubber.
4. The article of claim 1 , wherein the elastomeric material comprises a styrene-ethylene-butylene-styrene block copolymer.
5. The article of claim 1 , wherein the elastomeric material is selected from the group consisting of a styrene-isoprene-styrene block copolymer, styrene-butadiene-styrene block copolymer, styrene-isoprene block copolymer, styrene-butadiene block copolymer, synthetic isoprene, chloroprene rubber, polyvinyl chloride, silicone rubber, and a combination thereof.
6. The article of claim 1 , wherein the silicone-modified vinyl acetate polymer contains from about 17 atomic % to about 22 atomic % silicon.
7. The article of claim 1 , wherein the silicone-modified vinyl acetate polymer contains from about 15 atomic % to about 25 atomic % silicon.
8. The article of claim 1 , wherein the lubricant includes at leas one or a combination of the following: a quaternary ammoniun compound; a cationic, anionic, or nonionic, or amphoteric surfactant; a silicone or silicone-based component, and a silicone emulsion.
9. An article comprising a substrate body formed from an elastomeric material, said substrate body having a first surface; and a donning layer comprising a silicone-modified vinyl acetate polymer overlaying at least a portion of said first surface, said silicon-modifed vinyl acetate polymer contains from about 10 atomic % to about 30 atomic % of silicon.
10. The article according to claim 9 , wherein said donning layer is non-elastic and does not flake off of said first surface when under stress of being stretched and deformed.
11. The article according to claim 9 , wherein said silicone-modifed vinyl acetate polymer contains from about 15 atomic % to about 25 atomic % of silicon.
12. The article according to claim 9 , wherein said donning layer is present in am amount of about 0.1 mass % to about 2.5 mass % of said article.
13. The article according to claim 9 , wherein said article further includes a lubricating layer overlying at least a portion of said donning layer.
14. The article according to claim 13 , wherein said lubricant layer includes, either alone or in combination, at least one of the following: a silicone or silicone-based emulsion, a quaternary ammonium compound, a cationic surfactant, an anionic surfactant, a non-ionic surfactant, or a amphoteric surfactant.
15. The article according to claim 9 , wherein said elastomeric material comprises natural rubber.
16. The article according to claim 9 , wherein said elastomeric material comprises a nitrile butadiene rubber.
17. The article according to claim 9 , wherein said elastomeric material comprises a styrene-ethylene-butylene-styrene (SEBS) block copolymer.
18. The article according to claim 9 , wherein said elastomeric material is selected from the group consisting of a styrene-isoprene-styrene block copolymer, styrene-butadiene-styrene block copolymer, styrene-isoprene block copolymer, styrene-butadiene block copolymer, synthetic isoprene, chloroprene rubber, polyvinyl chloride, silicone rubber, and a combination thereof.
