Method for producing a metallised fabric, and resulting fabric

Abstract

The invention relates to a method for producing a metallised fabric, including a step of washing a woven substrate, the method including, after the washing step, the following steps: calendering the substrate by applying a compression force to the substrate, and vacuum-metallising the substrate in a rarefied atmosphere by depositing metal particles so as to form a layer of metal on the substrate.

1 - 9 . (canceled) 
     
     
         10 . A method for producing a metallized fabric, the method comprising:
 first washing a woven substrate comprising yarns having a maximum weight of 70 decitex in the warp direction and in the weft or filling direction; then   calendering the substrate by applying a compressive force to the substrate; and   performing vacuum metallization on the substrate, by deposition of metal particles to form a layer of metal on the substrate, in a rarefied atmosphere.   
     
     
         11 . The method as claimed in  claim 10 , wherein the substrate comprises synthetic fibers. 
     
     
         12 . The method as claimed in  claim 10 , wherein the substrate comprises microfibers. 
     
     
         13 . The method as claimed in  claim 10 , wherein the woven substrate comprises at least 42 warp yarns and 40 filling yarns per centimeter. 
     
     
         14 . The method as claimed in  claim 10 , wherein calendering the substrate comprises at least one pass for each side of the substrate. 
     
     
         15 . The method as claimed in  claim 10 , wherein performing vaccum metallization includes performing metal vapor deposition. 
     
     
         16 . The method as claimed in  claim 10 , wherein the formed layer of metal is aluminum. 
     
     
         17 . The method as claimed in  claim 10 , wherein during vacuum metallization, strips of substrate are alternated and placed end to end with strips of film to form a continuous strip that is introduced into the metallization machine. 
     
     
         18 . A metallized fabric that can be obtained by applying the method as claimed in  claim 10 .
