Abstract
The invention relates to a method for producing fabric-reinforced capillary membranes, particularly for ultrafiltration, in which a fabric tube (1) is coated with a polymer solution and is guided through a precipitation bath (6), where the polymer solution is converted into a microporous layer in the precipitation bath (6), and a membrane that is reinforced by the fabric tube is formed. According to the invention, the fabric tube coated with the polymer solution passes through the precipitation bath (6) from top to bottom, without mechanical contact, and exits through a nozzle (7) at the bottom. Liquid flows out of the nozzle (7), which liquid exerts a tensile force stabilizing the course of the coated fabric tube, on the capillary membrane (8) leaving the precipitation bath.
