Waterproof breathable high-vis arc resistant laminate

Abstract

A fabric for use in garments worn by electrical workers is constructed of at least three layers including a high visibility face fabric layer; an intermediate expanded polytetrafluoroethylene membrane layer, coated with polyurethane; and an inner layer comprised of flame resistant, high temperature fibers.

1 . A fabric comprised of at least three layers including a high visibility face fabric layer, an intermediate expanded polytetrafluoroethylene membrane layer; and an inner layer comprised of flame resistant, high temperature fibers. 
   
   
       2 . The fabric of  claim 1  wherein said face fabric layer comprises a plain-woven modacrylic based fabric. 
   
   
       3 . The fabric of  claim 2  wherein said face fabric layer has a weight of substantially 6.5 opsy. 
   
   
       4 . The fabric of  claim 1  wherein said inner layer comprises a tricot jersey material. 
   
   
       5 . The fabric of  claim 2  wherein said inner layer comprises a tricot jersey material. 
   
   
       6 . The fabric of  claim 1  wherein said face fabric layer is high-visibility yellow or orange in color. 
   
   
       7 . The fabric of  claim 1  wherein said inner layer has a weight of substantially 1.75 opsy. 
   
   
       8 . The fabric of  claim 1  wherein said three layers are laminated together using a flame resistant polyurethane adhesive applied between adjacent layers. 
   
   
       9 . The fabric of  claim 5  wherein said three layers are laminated together using a flame resistant polyurethane adhesive applied between adjacent layers. 
   
   
       10 . The fabric of  claim 1  wherein said membrane is coated with polyurethane. 
   
   
       11 . A fabric for use in garments exposed to electrical equipment comprising:
 a first outer layer constructed of plain woven modacrylic material;   a second intermediate layer constructed of an untreated, expanded polytetrafluorethylene membrane coated on one side with polyurethane or polyester; and   a third inner layer comprised of a tricot jersey material composed of flame resistant, high temperature fibers.   
   
   
       12 . The fabric of  claim 11  wherein said face fabric layer has a weight of substantially 6.5 opsy. 
   
   
       13 . The fabric of  claim 11  wherein said inner layer has a weight of substantially 1.75 opsy. 
   
   
       14 . The fabric of  claim 11  wherein said face fabric layer is yellow in color. 
   
   
       15 . The fabric of  claim 11  wherein said three layers are laminated together using a flame resistant polyurethane adhesive applied between adjacent layers.
