The effect of die temperature on the properties and structure of the PVDF hollow fiber by TIPS method with dipropyl ketone and phenyl salicylate as mixed dilute was investigated. The results showed that higher mechanical properties and larger pure water flux could be reached when the die temperature was between 180℃ to 190℃.
