A preparation method of fouling-resistant hollow fiber membrane and a fouling-resistant hollow fiber membrane prepared by the same

摘要

The present invention relates to a method for manufacturing a fouling-resistant hollow fiber membrane and a fouling-resistant hollow fiber membrane prepared by the above method, and more specifically, to the surface, preferably uniform, by spinning the polymer spinning solution while causing vortex in a spinning nozzle, A method for manufacturing a hollow fiber membrane in which a number of protrusions are continuously or discontinuously formed in a vertical or diagonal direction with respect to the lengthwise direction of the hollow fiber membrane to improve fouling resistance, thereby maintaining the physical properties of the hollow fiber membrane such as average pore size and pure permeability. It relates to a pollution-resistant hollow fiber membrane prepared by the method.
