Abstract
PURPOSE: To obtain the title hollow fibers having properties desirable for blood dialysis, by extruding a solution of a cellulose ester in a specific solvent and a swelling agent through an annular slit.
CONSTITUTION: A solution comprising a cellulose ester and a water-miscible organic solvent, e.g. acetone and a water-soluble acetin, e.g. mono- or diacetin, as a swelling agent, is extruded through an annular slit, and a liquid, e.g. conc, aqueous salt, is introduced into the filamentary material simultaneously to give the objective hollow fibers. The acetin provides semipermeable hollow fiber membranes, and can be eliminated readily by rinsing with water.
