Abstract
A non-woven web, comprising one or more polymeric fibers, wherein the number-average fiber diameter distribution of said one or more polymeric fibers conforms to a Johnson unbounded distribution. Non-woven webs comprising such polymeric fibers are rendered with mean-flow pore size and porosity desirable for specific filtration applications such as hepafiltration.
