| 摘要 |
A fiber-reinforced porous hollow fiber membrane which comprises both a hollow fiber membrane and a reinforcing fiber that is completely or partially buried in the hollow fiber membrane, wherein: the reinforcing fiber is arranged in a portion which spreads up to a depth corresponding to 90%, preferably 80%, of the thickness of the hollow fiber membrane as viewed from the inner or outer circumferential surface side of the membrane, said inner or outer circumferential surface side being not the side which is to come into contact with an object to be treated; and preferably at least 50vol% of the cross section of the reinforcing fiber is buried in the hollow fiber membrane. This fiber-reinforced porous hollow fiber membrane exhibits excellent permeability, excellent separation performance and excellent dynamic characteristics. |
