Abstract: The three main methods for preparation of hollow fiber membrane, i.e. solution spinning method, melt-
spinning-cold stretching method (MSCS) and thermally induced phase separation method (TIPS) are introduced in
this article. The preparation technology and pore-forming mechanism of the three methods were introduced respec-
tively, and the history and development of them are reviewed and discussed. The trends of preparation methods for
hollow fiber membrane are also indicated.
Key words: solution spinning method; melt-spinning-cold stretching method; thermally induced phase separa-
tion method; hollow fiber membrane; preparation methods; development
