Abstract: On fabrique une matière textile à revêtement, utilisée notamment comme tissu de filtration durable, à partir d'un substrat textile tel qu'un tissu tissé ayant un revêtement microporeux de polymère de fluorocarbone élastomère. On peut réaliser le substrat en aramide ou en sulfure de polyphénylène ou en fibres de verre. Le polymère élastomère peut être un terpolymère de tétrafluoroéthylène de pentafluoropropène de fluorure de vinylidène. On peut appliquer le revêtement microporeux sous forme d'émulsion aqueuse moussée séchée et broyée mécaniquement.

Abstract: A phase-separation member comprises a porous substrate (11) containing void spaces, a microporous polymer material (14) which at least partially impregnates the porous substrate by entering into the void spaces, and a layer of a fluoropolymer applied to the outer face of the coagulated polymer material so that the layer (16) of fluoropolymer material remains predominantly at the surface.

Abstract: A coated textile material, particularly for use as a durable filter fabric, is made from a textile substrate, such as a woven fabric, having a microporous coating of an elastomeric fluorocarbon polymer. The substrate may be formed from aramid or polyphenylene sulphide or glass fibres. The elastomeric polymer may be a vinylidene fluoride pentafluoropropene tetrafluoroethylene terpolymer. The microporous coating may be applied as a foamed aqueous emulsion which is dried and mechanically crushed.
