Abstract
Methods are disclosed by which melt-formed inorganic fibers may be processed to form a gravity-laid inorganic fiber web. The gravity-laying process comprises mechanically separating the melt-formed inorganic fibers and collecting the fibers, and may comprise blending the melt-formed inorganic fibers with other inorganic fibers and/or with inorganic particulate additives.
