Zusammenfassung:	A method for fabricating a filter material includes the following steps. A polyvinyl alcohol solution and a thermal cross-linking agent are provided, wherein the thermal cross-linking agent is a blocked isocyanate. The polyvinyl alcohol solution and the thermal cross-linking agent are evenly mixed to form a mixture solution, and the ratio of the polyvinyl alcohol solution and the thermal cross-linking agent is between 100: 1 and 2: 1. The mixture solution is put into a spinning device to perform an electro-spinning process to form a plurality of nano-fibers. A hot-press treatment process is performed to the nano-fibers so as to form the filter material.
