FIBER-REINFORCED TYPE HOLLOW FIBER MEMBRANE

摘要

PROBLEM TO BE SOLVED: To provide a fiber-reinforced type hollow fiber membrane excellent in water permeability. SOLUTION: The fiber-reinforced type hollow fiber membrane has a semipermeable membrane layer on the outer surface of a braid and the semipermeable membrane layer is formed from a liquid film forming composition containing 15-30 mass% of a polysulfone type resin and/or a polyether sulfone type resin (a), 40-80 mass% of a good solvent (b) and 1-45 mass% of a poor solvent (containing no polyalkylene glycol) (c).
