METHOD FOR PRODUCING HOLLOW FIBER MEMBRANE AND HOLLOW FIBER MEMBRANE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a hollow fiber membrane, by which the hollow fiber membrane having a high strength and a high water- penetrable performance can be produced from a polyvinylidene fluoride-based resin having high chemical resistance at a low cost in a state scarcely giving loads to the environments. SOLUTION: The method for producing the hollow fiber membrane is characterized by extruding and coagulating a solution containing at least a polyvinylidene fluoride-based resin and having a viscosity of 10 to 200 Pa.s into a cooling bath.
