Nonwoven fabric, method for producing nonwoven fabric, and filter |
| abstract |
The present invention provides a nonwoven fabric having excellent filtration accuracy and filtration life when used as a filter, a method for producing the nonwoven fabric, and a filter. A nonwoven fabric (10) is formed of fibers (11) in the range of 0.10 μm to 5.00 μm. The nonwoven fabric (10) includes a coarse layer section (12) and a dense layer section (14). The coarse layer section (12) has a porosity Pc of at least 90% and an average pore diameter Dc in the range of 0.5 μm to 50 μm. The dense layer section (14) has a porosity Pd of at least 70% and a relative standard deviation of the pore diameter distribution of 20% or less. |
