The invention relates to a solid-liquid filtration cloth comprising a base fabric woven from polymer yarns (1, 2). After the weaving, the base fabric has been treated by a polymer material, which has better electric conductivity than the polymer yarns of the base fabric. The polymer treatment is carried out by means of a polyaniline solution or a polypyrrole solution, for instance. After the polymer treatment, at least the yarns on the surface of the base fabric comprise a coating (3) of an electrically conductive polymer.
La présente invention concerne une toile filtrante pour système solide-liquide comprenant un tissu de base tissé à partir de filés polymères (1, 2). Après le tissage, le tissu de base a été traité par un matériau polymère dont l'électro-conductivité est supérieure à celle des filés polymères du tissu de base. Le traitement aux polymères s'effectue au moyen d'une solution de polyaniline ou de polypyrrole notamment. Après le traitement aux polymères, les filés de la surface du tissu de base au moins comprennent un revêtement d'un polymère électro-conducteur.
