ABSTRACT:
The present invention provides a polymeric, particularly aramid, fiber filtration sheet having a relatively small pore size and high pore uniformity. The present inventive aramid fiber filtration sheet preferably has a titer reduction against bacteria such as Pseudomonas diminuta. The present invention also provides a method of preparing reduced-diameter aramid fibers, as well as a method of preparing an aramid fiber filtration sheet from such reduced-diameter aramid fibers. The present invention further provides a method of treating a fluid by passing a fluid through the present inventive aramid fiber filtration sheet, as well as a filter element incorporating the present inventive aramid fiber filtration sheet.
