HOLLOW FIBER MEMBRANE HAVING IMPROVED HYDROPHILICITY AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a hollow fiber membrane with fouling mitigation effects and a production method thereof. According to the present invention, the hollow fiber membrane exhibits outstanding mechanical strength and water permeability by uniformly controlling the discharging ratio and the content of a spinning solution and an internal coagulant in the production of the hollow fiber membrane. In addition, it is also possible to provide a hollow fiber membrane with excellent fouling mitigation effects. To this end, the hollow fiber membrane has a hollow structure including an outer surface layer and an inner surface layer.
