Fibrous filtration media for hot oil filtration includes a nonwoven fibrous web containing synthetic fibers and at least about 15 wt. %, based on total weight of the fibrous web, of a binder component selected from thermoset binder resins and/or binder fibers. The synthetic fibers of the fibrous web will contain from about 2 wt. % to about 65 wt. %, for example between about 10 wt. % to about 50 wt. %, based on total weight of fibers in the fibrous web, of thermoplastic synthetic microfibers having an average diameter of less than 5 μlτl. The synthetic fibers are bonded together with the binder component to form the fibrous web which is capable of forming a self-supporting, pleated oil filter media which retains pleats upon contact with oil having a temperature in a range encountered in an internal combustion engine.

Self-supporting pleatable fibrous web especially useful as oil filter media and oil filter comprising the same

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.
