Continuously chemically resistant spacer textile

Abstract

The invention relates to a spacer textile ( 1 ) including a top textile ( 2 ), a bottom textile ( 3 ) and a spacer layer ( 5 ), wherein the top textile ( 2 ) and the bottom textile ( 3 ) are connected together by the spacer layer ( 5 ). The top textile ( 2 ), the bottom textile ( 3 ) and the spacer layer ( 5 ) are monofilament fibers from inert fluorocarbons. The invention relates additionally to the use of the spacer textile ( 1 ) according to the invention as at least in part sheathing of an electrode ( 13, 14 ) in an electroplating bath ( 11 ), as a lining of operating, bearing and/or transport surfaces ( 31 ), or as filter or support material in chemically aggressive media.
