| 摘要 |
The present invention relates to a production method for a hollow fiber separation membrane which comprises: a first ring-shaped block having a through hole therein and a plurality of first spinning holes around the through hole; and a second ring-shaped block rotating along an outer circumferential surface of the first ring-shaped block around the through hole, and having a plurality of second spinning holes formed thereon. According to the present invention, the separation membrane is produced by means of a spinneret, of which the second ring-shaped block rotates in one direction, whereas the first ring-shaped block rotates in the opposite direction of the second ring-shaped block or does not rotate at all. The production method of the present invention ensures excellent process efficiency, and the hollow fiber separation membrane produced thereby also shows outstanding durability, high pressure resistance, and fouling resistance as well. |
