    摘要: A process for manufacturing of an asymmetric hollow fiber membrane, comprising the steps of extruding a polymer solution through the outer ring slit of a hollow fiber spinning nozzle, simultaneously extruding a center fluid through the inner bore of the hollow fiber spinning nozzle, into a precipitation bath, whereby the polymer solution contains 10 to 26 wt-% of polysulfone (PSU), polyethersulfone (PES) or polyarylethersulfone (PAES), 8 to 15 wt-% polyvinylpyrrolidone (PVP), 55 to 75 wt-% N-alkyl-2-pyrrolidone (NAP) and 3 to 9 wt-% water the centre fluid contains 70 to 90 wt-% N-alkyl-2-pyrrolidone (NAP) and 10 to 30 wt-% water, and the precipitation bath contains 0 to 20 wt-% N-alkyl-2-pyrrolidone (NAP) and 80 to 100 wt-% water.
