ABSTRACT:
A nonwoven fibrous web material that contains cellulose ester fibers, cellulose ester fibrets and a minor amount of activated fusible fibers uniformly dispersed throughout is particularly well suited as a filter media. The activated fusible fibers are effective for retaining within the filter web any particulate material resulting from corrugation without adversely affecting the filtration efficiency of the cellulose ester fibers and fibrets. Alternatively, the fibrous web material may include an effective amount of natural cellulosic fibers.
