| titleOfInvention | Polyether sulfone microporous hollow yarn membrane and its production |
| abstract | PURPOSE: To obtain a polyether sulfone hollow yarn membrane excellent in the separability of a solute and water transmitting flow flux, by forming a three-layered structure comprising dense layers in the vicinity of both surfaces and an intermediate layer having a reticulated structure so that the void ratio of a membrane as a whole is a specific range and the elongation of the membrane in a wet state is a specific value or more. n CONSTITUTION: A raw spinning solution is prepared from polyether sulfone, a solvent such as dimethylsuloxide and water-soluble polyhydric alcohol such as polyethylene glycol to be extruded from the outer ring part of a double tube nozzle and a core solution is simultaneously emitted from the inner ring part to perform the spinning of a hollow yarn while the formed hollow yarn is guided to a water coagulation bath through the open air and subsequently washed with water. By this method, a polyether sulfone microporous hollow yarn membrane, of which the void ratio is 70W90% and the elongation in a wet state is 50% or more, having a three-layered structure is obtained. n COPYRIGHT: (C)1986,JPO&Japio |
