| titleOfInvention | Hollow fiber heterogeneous membrane and method for producing the same |
| abstract | (57) [Summary] [Structure] A hollow fiber membrane obtained by melt-extruding a crystalline thermoplastic resin containing poly-4methyl-1-pentene as a main component into a hollow fiber shape, and then stretching the melt. Has an area open area ratio of 3% or less and a crystallinity of 55% only on the outer surface After the hollow fiber heterogeneous membrane characterized by having the above dense layer and having the porous layer inside and the crystalline thermoplastic resin are melt-extruded under the conditions of a tension of 0.8 g to 6.0 g Then, the hollow fiber heterogeneous membrane is obtained by stretching. [Effect] The hollow fiber heterogeneous membrane of the present invention has excellent gas permeation characteristics and gas separation characteristics, and since a dense layer is stably formed on the outer surface of the membrane, the overall strength of the membrane is high. It is useful as a liquid contact membrane, a gas-gas separation membrane, a diaphragm for artificial lungs, a deoxygenation of ultrapure water, and a degassing membrane for dissolved gas such as deoxygenation of boiler ring water. |
