Method for production of hollow fiber membrane. |
摘要 |
<p>A method comprising the steps of discharging a spinning dope through an annular spinning nozzle and, at the same time, introducing a non-coagulating liquid for the spinning dope into the central cavity in a hollow fiber of the spinning dope being discharged, and then introducing the discharged fiber of the spinning dope into a coagulating liquid thereby solidifying the discharged fiber into a hollow fiber membrane, which method is characterized by incorporating a surface modifying agent in said non-coagulating liquid thereby modifying the inner surface behavior of the produced hollow fiber membrane.</p> |
