Abstract: A fibrous media suitable for an oil filter comprising a fibrous web formed from synthetic fibers; optionally at least one additive, and a thermoset binder present at a concentration of at least 15 wt.-% by weight of the fibrous web and/or at least one binder fiber, wherein the synthetic fibers comprise up to 30 wt.-%, preferably up to 20 wt.-%, glass fibers, based on the total weight of the fibers. The fibers are bonded with the thermoset binder and/or the at least one binder fiber to form a web; and the fibrous media is capable of forming a self-supporting, pleated oil filter media which is capable of retaining pleats upon contact with oil having a temperature in the range encountered in a combustion engine.

Abstract: Disclosed is a filter medium useful for flue gas filtering that comprises a non-woven fibrous web having at least 80 weight percent of meta-aramid fibers and from 0.1 to 20 weight percent of meta-aramid fibrids, based on weight of fibers and fibrids. The non-woven fibrous web can have average pore size of 20 to 80 micrometers, maximum pore size of 100 micrometers, dry Mullen burst strength of at least 7 kg/cm2, retention of 80% of the dry Mullen burst strength after acid cycling, a filtration efficiency of at least 95% for 2.5 micron particle, and/or a shrinkage of less than 2% after being heated in a dry oven at 205 ° C. for 2 hours. A method of making the filter medium comprises wet-laying a furnish of the meta-aramid fibers and the meta-aramid fibrids; drying to form the non-woven fibrous web; preferably, calendering; and optionally saturating with binder resin and curing.
