A non-woven fabric is formed from fibres which are substantially unbonded. Copolymerised to the surface of the fibres a vinyl monomer is capable of reacting with an acid or a base to form a salt directly or indirectly by a reaction which involves exposure of the fabric to ultraviolet radiation while impregnated with a solution of the vinyl monomer. The fabric is suitable for use as an electrode separator in an electrochemical device.

L'invention concerne un textile non tissé, qui est formé de fibres sensiblement non liées. Un monomère de vinyle, copolymérisé à la surface des fibres, peut réagir avec un acide ou une base pour former un sel, directement ou indirectement, par une réaction dont la mise en oeuvre consiste à exposer le textile aux rayonnements ultraviolets tout en l'imprégnant d'une solution de monomère de vinyle. Ce tissu peut être utilisé comme séparateur d'électrode dans un dispositif électrochimique.
