摘要 (Abstract) |
|
| Provided is a method of fabricating a filter media, which includes the following steps. A plurality of first fibers are formed by a first spinning device. A plurality of second fibers are formed by a second spinning device. A film with a three-dimensional non-woven structure constructed by the first and the second fibers are collected on a reception device. The diameter of the first fibers is between 1 μm to 50 μm, and the diameter of the second fibers is between 1 nm to 1000 nm. The second spin | |
