| Abstract: | Electrospinning is a relatively simple method to produce submicron fibers from solutions of different polymers and polymer blends. The extensive application in future of electrospinning nanofibers is filtration. The objective is to study on the filtration properties of electrospinning nanofibers. During the experiments,nanofibers layers with different area weight are placed on the spunbond or meltblown sublayers. After the cross-linking, the filtration properties are tested. The result shows that the filtration efficiency and filtration resistance both increase sharply when nanofibers layers are added to the sublayers. Moreover, the pore diameter of nanofibers layers are much smaller than the sublayers. |
