Abrasion and cut resistant coating and coated glove

Abstract

An elastomeric abrasion and cut resistant coating or coated glove, including a polymeric, elastomeric, or latex layer and, optionally, a fabric liner, is disclosed. Methods for manufacturing an elastomeric abrasion and cut resistant coating or coated glove substantially are also disclosed.

What is claimed is: 
     
         1 . A method for making an abrasion and cut resistant glove, comprising:
 dipping a glove-shaped former into a strong coagulant;   applying a polymeric composition to the former, thereby disposing a coating onto the former;   dipping the former having a coating thereon into a weak acid; and   dipping the polymeric layer into a strong coagulant.   
     
     
         2 . The method of  claim 1 , wherein the polymeric composition is foamed. 
     
     
         3 . The method of  claim 1 , wherein the weak acid comprises tricarboxylic acid. 
     
     
         4 . The method of  claim 1 , wherein the polymeric composition further comprises at least one of natural polyisoprene, synthetic polyisoprene, carboxylated acrylonitrile butadiene, non-carboxylated acrylonitrile butadiene, nitrile-butadiene, polychloroprene, polyvinyls, butyl latex, styrene-butadiene (SBR), styrene-butadiene latex, styrene-isoprene-styrene (SIS), styrene-ethylene/butylene-styrene (SEBS), styrene-acrylonitrile (SAN), polyethylene-propylene-diene, water-based polyurethane, an anionically stabilized polymer composition, solvent-based polyurethane, or combinations or blends thereof. 
     
     
         5 . The method of  claim 1 , further comprising dressing the former with a fabric liner before the dipping into a strong coagulant step. 
     
     
         6 . The method of  claim 5 , further comprising compacting the fabric liner before dressing the former with the fabric liner. 
     
     
         7 . The method of  claim 6 , wherein the compacting step further comprises a hot washing process, whereby the surface of the liner yarn is modified to promote adhesion to the polymeric layer and increase abrasion resistance. 
     
     
         8 . The method of  claim 1 , wherein dipping the polymeric layer into a strong coagulant is followed by a second dipping of the polymeric layer into a coagulant, a second dipping into a weak acid and a second dipping into a strong coagulant. 
     
     
         9 . A method for making an abrasion and cut resistant glove, comprising:
 dressing a fabric liner onto a glove shaped-former;   applying a strong coagulant to the fabric liner;   dipping the fabric liner into a polymeric composition, wherein a polymeric coating is disposed onto the fabric liner;   dipping the former having a coating thereon into a weak acid;   dipping the polymeric layer into a strong coagulant; and;   curing the polymeric layer to form an abrasion resistant glove, wherein the glove formed has an EN388 abrasion resistance level of at least 3.   
     
     
         10 . The method of  claim 9 , wherein the fabric liner comprises a 15 or 18 gauge knitted liner. 
     
     
         11 . The method of  claim 9 , wherein the fabric liner comprises a nylon 6 or nylon 66 yarn or blends thereof. 
     
     
         12 . The method of  claim 9 , wherein the glove has an EN388 cut resistance level of 2. 
     
     
         13 . The method of  claim 9 , wherein the coating is foamed. 
     
     
         14 . The method of  claim 9 , wherein the thickness of the polymeric layer is between 0.1 and 0.3 mm. 
     
     
         15 . The method of  claim 9 , wherein the polymeric, composition comprises at least one of natural polyisoprene, synthetic polyisoprene, carboxylated acrylonitrile butadiene, non-carboxylated acrylonitrile butadiene, nitrile-butadiene, polychloroprene, polyvinyls, butyl latex, styrene-butadiene (SBR), styrene-butadiene latex, styrene-isoprene-styrene (SIS), styrene-ethylene/butylene-styrene (SEBS), styrene-acrylonitrile (SAN), polyethylene-propylene-diene, water-based polyurethane, an anionically stabilized polymer composition, solvent-based polyurethane, or combinations or blends thereof. 
     
     
         16 . The method of  claim 9 , wherein the glove formed has an EN388 abrasion resistance level of at least 4. 
     
     
         17 . The method of  claim 9 , wherein the cured coating layer is through-hardened. 
     
     
         18 . The method of  claim 9 , wherein the cured coating layer comprises three gelled layers.
