Abstract: A method for filtering airborne particulates is described. The method includes providing an exhaust hood, and the exhaust hood defines an intake and the exhaust hood being adapted to receive airborne particulates via the intake. The method also includes conveying a portion of a filter media from a media source area to an active media area, transferring the portion of the filter media from the active media area to a media discard area, the media discard area and the media source area being disposed on substantially opposed sides of the active media area, and severing the portion of the filter media in the media discard area from a remainder of the filter media.

Abstract: A method of forming a random fiber web using pneumatic fiber feeding system is disclosed. The method includes providing a plurality of moveable apparatuses including a lickerin and a feeder, the lickerin configured to remove a plurality of fibers from a fibrous mat delivered to adjacent the lickerin by the feeder. The method also includes doffing the plurality of fibers from the lickerin at a doffing location within the system. The method also includes communicating an air supply to entrain the plurality of fibers with the air supply after the doffing. The method also includes controlling the air supply within a flow path between the lickerin and a collector. The method also includes collecting the plurality of fibers from the air supply on a collector to form the random fiber web.

Abstract: A scouring article include a three-dimensional non-woven web of fibers bonded to one another to form a lofty, non-woven substrate. An abrasive coating is coated on the substrate. The abrasive coating includes a binder; a first plurality of abrasive particles and a second plurality of abrasive particles dispersed in the binder. The first plurality of inorganic abrasive particles has a Mohs' hardness of 7 greater and a median particle size in the range of 20 microns to 100 microns. The second plurality of organic abrasive particles has a Mohs' hardness in the range of 1 to 5 and a median particle size greater than 100 microns. The average surface roughness created by use of the scouring article, according to the surface roughness test, is less than 8 microns.
