| titleOfInvention | Hollow fiber-seaped porous membrane |
| abstract | PURPOSE: To improve the fragility of a hollow fiber and to eliminate the generation of a leak by constituting an outer-shell layer of the hollow fiber-shaped porous membrane of a porous structure denser than that of the reticular inner-shell layer, and specifying the ratio of the mean pore diameter of the inner-shell layer to the mean pore diameter on the outer surface, the mean porosity of the wall membrane, and the water permeability of the membrane. n CONSTITUTION: Cellulose acetate, polymethyl methacrylate, and cellulose nitrate are dissolved into a solvent, and a swelling agent and an inorganic salt are added to the soln. to obtain a spinning soln. The soln. is spewed from an annular spinneret, and immediately introduced into a coagulation bath. A liquid having the same composition as the coagulation bath is simultaneously charged into the bath from the inside of the spinneret. Accordingly, a dense outer-shell layer is formed in the vicinity of the outer surface and 2-layered structure can be formed with the reticular inner-shell layer. The ratio of the mean pore diameter of the inner-shell layer to the mean pore diameter of the outer surface is regulated to 1W3, the mean porosity of the whole of the wall membrane to ≥60%, and the water permeability of the porous membrane to 1,000W 10,000ml/m 3 .hr.mmHg, respectively. Consequently, a hollow fiber having excellent separation efficiency of plasma can be obtained. n COPYRIGHT: (C)1985,JPO&Japio |
