Abstract

PURPOSE: Semi-dry, semi-wet spinning of a polymer solution is conducted by extruding the solution from ring-shape slits simultaneously with injecting a liquid into the center of the fibers, thus producing hollow fibers having balanced round crosssection, uniform wall thickness and high permeation selectivity.
