A method of treating tough inorganic fiber bundles including opening a plurality of the tough inorganic fiber bundles such that tough inorganic fibers can be dispersed in a liquid slurry to lay down a homogenous fiber aggregate, wherein the tough inorganic fibers have a crush settle volume of greater than 250 ml, optionally greater than 450 ml. Also, a method of treating tough inorganic fiber bundles including dispersing a plurality of the tough inorganic fiber bundles in a slurry with a dilution of about 0.1% to about 2%, optionally about 0.1% to about 1%, effective to lay down a homogenous fiber aggregate, wherein the tough inorganic fibers have a crush settle volume of greater than 250 ml, optionally greater than 450 ml.

Treatment of tough inorganic fibers and their use in a mounting mat for exhaust gas treatment device

A mat for mounting a monolith, the mat comprising a first inorganic fiber layer, where the mat has a front edge intended to form a gas facing edge in use, a rear edge opposite thereto and side edges extending between the front and rear edges, wherein the first inorganic fiber layer at a first side edge of the mat, and/or at a second side edge of the mat is cut at an acute angle to the thickness direction of the mat.

Mounting mat

A mat for supporting a monolith, the mat comprising one or more first portions comprising fibers at least partially coated with an erosion resistant inorganic (e.g. silica) gel composition or a precursor thereof.
