PRODUCTION METHOD OF POROUS HOLLOW FIBER MEMBRANE

摘要

PROBLEM TO BE SOLVED: To provide a simple production method of a hollow fiber membrane having a small diameter or a hollow fiber membrane having hydrophilicity. SOLUTION: The porous hollow fiber membrane is produced by applying a film-forming solution to form a porous membrane on the circumference of soluble fibers and curing the solution and then dissolving soluble fibers.
