Abstract: A method of making nonwoven fibrous materials suitable for use in a pollution control device or as a firestop, where the method comprises: providing a first slurry comprising water, first inorganic fibers, a first organic binder, and a first neutral pH flocculent; removing first waste water from the first slurry; optionally forming a first nonwoven fibrous material from the first slurry; providing a second slurry comprising a quantity of the first waste water, an optional quantity of relatively clean water, second inorganic fibers, a second organic binder, and a second flocculent that is the same and/or a different flocculent than that used in the first slurry; and forming a second nonwoven fibrous material from the second slurry. The addition of the first waste water in the second slurry does not adversely affect the flocculation of the second organic binder in the second slurry.

Abstract: A structure comprising at least one inorganic layer comprising inorganic materials suitable for use in a pollution control device. A friction-inducing material is disposed on at least one side of the inorganic layer. The deposited friction-inducing material defines a higher friction area exhibiting a static coefficient of friction higher than that of the inorganic materials. A lower friction layer is disposed so as to cover at least a portion of the higher friction area and define an exposed surface area of the structure. The exposed surface area exhibits a lower static coefficient of friction than that of the higher friction area. The lower friction layer no longer covers a substantial portion of the higher friction area, after the pollution control device is assembled.

Abstract: Compositions that include a mixture of biosoluble inorganic fibers and a micaceous binder are described. The compositions can be prepared free of refractory ceramic fibers that are respirable but durable in a physiological medium. The compositions are typically in the form of a sheet material or a paste and can be used, for example, as a protective packing material around the pollution control element or as an insulating material in the end cone region in a pollution control device. Sheet materials formed from the compositions have an area of a X-Y plane that decrease less than about 6 percent when heated to about 900° C.

Abstract: A flexible fibrous material comprises inorganic fibers and a binder and methods of making the same. The binder comprises at least one of: a first organic polymer having anionic groups and a flocculent, the flocculent comprising a second organic polymer having cationic groups; or a reaction product of the first organic polymer and the flocculent. Flexible fibrous material according to the present invention may be used as components in certain pollution control devices.
