Abstract
PURPOSE: To raise water permeability and compaction resistance, by providing dense layers on the inside and outside of a polysulfone hollow fiber membrane, and forming a spongelike texture layer in contact with these dense layers.
CONSTITUTION: Polysulfone resin (5W35wt%) and 1W35wt% nonsolvent, such as a saturated polyol of 2W4 carbon number are mixed with a good solvent having ≥100°C boiling point and low volatility to prepare a spinning solution. This solution is forced out of a circular nozzle, and simultaneously, a solidifying liquid consisting of a mixture of a good solvent and a nonsolvent for polysulfone is introduced in the core part of the circular nozzle to solidify the spinning solution to prepare a hollow fiber membrane having ≤0.025μm hole diameter dense layers on both its inside and outside, and spongelike texture layers of 0.025W3μm average fine hole diameter in contact with the dense layers, m-Cresol, chlorobenzene, etc. are usable for a good solvent for polysulfone, and ethylene glycol, glycerin, etc. are usable for a non solvent for it.
