Claim Text:
1. A structure for use in a pollution control device, said structure comprising: at least one inorganic layer comprising inorganic fibers suitable for use in a pollution control device, with said at least one inorganic layer having opposite sides, and each said side defining a major surface area; a friction-inducing inorganic material disposed on at least a portion of the major surface area, of at least one of the sides of said at least one inorganic layer, so as to define a higher friction area; and a lower friction layer comprising organic material disposed so as to cover at least a portion of said higher friction area and define an exposed surface area of said structure, with said exposed surface area exhibiting a lower static coefficient of friction than that of said higher friction area, wherein said lower friction layer is operatively adapted so as to no longer cover a substantial portion of said higher friction area, sometime after said structure has been used in a pollution control device.
