Abstract

A fluorine-free chemical treatment applicable to nonwoven media to provide high hydrophobicity and glue repellency without impacting product porosity/permeability. The fluorine-free chemical treatment incudes application of a water repellent including an acrylate copolymer optionally containing silicon functionalities, and/or optionally admixed with a polyurethane resin compound. The acrylate copolymer is used in combination with a non-fluorinated hydrophobic binder including a styrene moiety. Also disclosed are non-woven media including the acrylate copolymer containing silicon functionalities, and/or admixed with a polyurethane resin compound.

A self-cleaning filtration media for use in hydrocarbon fluid filtration applications has a first layer on an upstream side and a second layer on a downstream side of the self-cleaning filtration media. The first layer is composed of polyethersulfone nanofibers having a diameter of 50-1000 nm (0.05-1 micron) and a basis weight of at least 1 gsm. The second layer is a nonwoven substrate suitable for filtration applications. The self-cleaning filtration media exhibits a dust holding capacity of at least 6 mg/cm2 and a filtration efficiency of greater than 90% for 4 micron particles when the self-cleaning filtration media is tested according to ISO 19438 for fuel filtration and according to ISO 4548-12 for oil filtration. When the second layer includes glass fibers, the self-cleaning filtration media has a dust holding capacity of at least 10 mg/cm2 and a filtration efficiency of greater than 99% for 4 micron particles when the self-cleaning filtration media is tested according to ISO 19438 for fuel filtration and according to ISO 4548-12 for oil filtration. The self-cleaning filtration media also has a fuel-water separation efficiency of at least 99% when a flat sheet is tested according to ISO 16332; and a lifetime of at least 90 minutes when tested with fuel and oil according to ISO 19438 and Iso 4548-12 using Medium Test Dust and a pressure drop of 70 kPa.

Abstract

A filtration media with improved filtration, strength, tear resistance and air permeability in the form of a relatively thin and lightweight wet-laid fibrous web that has a wet Mullen ratio of 60% to 80% to ensure that the media is flexible enough to be formed into a fluted structure, and strong enough to retain the fluted structure when wound into a roll and to permit further processing without the media becoming too brittle. The filtration media comprises a blend of cellulose and synthetic fibers having a weight percent of 81 wt % to 87 wt % of a weight of the media and a resin binder having a weight of 13 wt % to 19 wt % (preferably about 16 wt %) of the weight of the media.

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

A filtration media with improved filtration, strength, tear resistance and air permeability in the form of a relatively thin and lightweight wet-laid fibrous web that has a wet Mullen ratio of 60% to 80% to ensure that the media is flexible enough to be formed into a fluted structure, and strong enough to retain the fluted structure when wound into a roll and to permit further processing without the media becoming too brittle. The filtration media comprises a blend of cellulose and synthetic fibers having a weight percent of 81 wt % to 87 wt % of a weight of the media and a resin binder having a weight of 13 wt % to 19 wt % (preferably about 16 wt %) of the weight of the media.

Abstract

A filter sheet media (1) for air/gas filtering applications fulfilling the criteria of standard EN779:2012 class M6 filter media, the filter sheet media (1) comprises: a first group of glass fibers (20) having a fiber diameter in a range of greater or equal to 6 μm up to 20 μm: a second group of glass fibers (30) having a fiber diameter in a range of 0.2 μm to less than 6 μm; a binder (40); the second group of glass fibers (30) have a fiber distribution gradient over the thickness (13) of the filter sheet media (1) so that the second group of glass fibers (30) are distributed through the thickness (13) of the filter sheet media (1), the filter sheet media (1) having more second group of glass fibers (30) near the first surface (11) than the second surface (12). Also disclosed is a method for manufacturing.
