Abstract

See full text

Fibrous filtration media and methods of making and using the same are provided whereby the media includes a wet-laid nonwoven fibrous web having from about 20 wt. % to about 80 wt. %, based on total weight of fibrous web, of bicomponent staple fibers, and from about 10 wt. % to about 50 wt. %, based on total weight of the fibrous web, of fibrillated lyocell staple fibers. The fibrous web exhibits a wet burst strength of greater than 3 bar, for example between about 3 bar to about 6 bar and is especially suitable for use in filtering process fluids (e.g., water) associated with wire electron discharge machining (WEDM).
