Abstract

1374704 Ultra filtration membrane ALFALAVAL AB 4 May 1972 [1 June 1971] 20755/ 72 Heading B1X A tubular filter membrane (e.g. for ultra filtration or reverse osmosis has a wall permeable to liquid and a tubular reinforcing means which is completely embedded in the membrane material and consists of threads crossing each other, the threads having a higher tensile strength than the membrane material and constituting the only support for the membrane material, the threads extending inside the membrane material, in two substantially mutually perpendicular directions, one of the directions being generally axial. The reinforcement may be a tubular woven superpolyamide fabric, and the membrane may be cellulose acetate.
