Wet/dry high-temperature glove

Abstract

The invention concerns a multilayer glove comprising an outer layer consisting essentially of aramid fibers, an inner layer consisting essentially of a thermoset material, and a hand contact layer comprising animal or plant fiber, wherein the inside palm of the glove remains below about 49 C (120 F), at least 15 seconds after the glove is immersed in water at room temperature for 2 min, removed from the water, hung in a vertical position for 5 min, and heated at a temperature of about 280 C (536 F).

1 . A multilayer glove comprising:
 an outer layer consisting essentially of aramid fibers,   an inner layer consisting essentially of a thermoset material, and   a hand contact layer comprising polyester, animal or plant fiber,   wherein the inside palm of said glove remains below about 49 C (120 F), at least 15 seconds after the glove is immersed in water at room temperature for 2 min, removed from the water, hung in a vertical position for 5 min, and heated at a temperature of about 280 C (536 F).   
   
   
       2 . The glove of  claim 1  wherein the outer layer is poly(metaphenylene isophthalamide), poly(paraphenylene terephthalamide) spun yarns. 
   
   
       3 . The glove of  claim 2  wherein the poly(metaphenylene isophthalamide) is present in about 90%-10% of the outer layer and poly(paraphenylene terephthalamide) is present in about 10%-90% of the outer layer. 
   
   
       4 . The glove of  claim 1  wherein the outer layer is woven, non-woven or knit fabric. 
   
   
       5 . The glove of  claim 1  wherein the thermoset material consists essentially of nitrile rubber, butyl rubber, fluoroelastomer, silicone or mixtures thereof. 
   
   
       6 . The glove of  claim 1 , wherein the inside palm of said glove remains below about 49 C (120 F), at least 28 seconds after the glove is immersed in water at room temperature for 2 min, removed from the water, hung in a vertical position for 5 min, and heated at a temperature of about 280 C (536 F). 
   
   
       7 . A multilayer glove comprising:
 an woven, non-woven or knit fabric spun yarn outer layer consisting essentially of about 90%-10% poly(metaphenylene isophthalamide) and 10%-90% poly(paraphenylene terephthalamide),   an inner layer consisting essentially of nitrile rubber, butyl rubber, fluoroelastomer, silicone, or mixtures thereof, and   a hand contact layer comprising polyester, animal, or plant fiber,   wherein the inside palm of said glove remains below about 49 C (120 F), at least 15 seconds after the glove is immersed in water at room temperature for 2 min, removed from the water, hung in a vertical position for 5 min, and heated at a temperature of about 280 C (536 F).   
   
   
       8 . The multilayer glove of  claim 7 , wherein the inside palm of said glove remains below about 49 C (120 F), at least 28 seconds after the glove is immersed in water at room temperature for 2 min, removed from the water, hung in a vertical position for 5 min, and heated at a temperature of about 280 C (536 F).
