MULTILAYERED HOLLOW FIBER MEMBRANE HAVING HIGH STRENGTH AND HIGH PERMEABILITY, AND METHOD OF MANUFACTURING SAME

摘要

The present invention relates to a hollow fiber membrane having both high strength and high permeability. Since the hollow fiber membrane of the present invention is formed by simultaneously spraying a coating solution including a spinning solution and a binder, or by simultaneously spraying the spinning solution, a binder solution, and the coating solution, not only does the hollow fiber membrane have high strength and high permeability, but an inner support layer and an outer coating layer also have a strong coupling force to prevent separation.
