Reinforced asymmetric capillary membranes

摘要

The present invention is related to a process for manufacturing asymmetric self-supporting braid reinforced capillary ultra- or micro-filtration membranes (1), comprising the subsequent steps of pulling a braid through a spinneret and coating the braid (5) with dope, wherein the braid is impregnated with a liquid prior to said coating step, said liquid having a viscosity arranged to prevent dope embedding said braid (5).
