摘要： A pleated paper filter element is disclosed which is formed from a mechanically-treated filter paper (10') which has the side thereof opposite to the wire-side (12) mechanically teased so as to form thereon an open, textured layer (18) of raised fibers. The starting material used is a standard, commercially-available filter paper which is resin-impregnated with an uncured phenolic resin. The pleated paper filter element formed from the treated filter paper (10') displays, after the element has been heated to cure the resin, a substantial increase of up to 73.5% in the dust-holding capacity over a like element formed from the standard, commercially-available filter paper.
