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 formed aqueous emulsion which is dried and mechanically crushed.
