ALTERNATE COMMINGLING OF MINERAL FIBERS AND ORGANIC FIBERS

摘要

A method for producing mineral fibers (16) includes centrifuging mineral fibers (16) from one or more rotary mineral fiber spinners (10) to establish one or more downwardly moving veils (22) of mineral fibers (16) positioned above a collecting surface (12), centrifuging organic fibers (34) from molten organic material (32) using one or more rotary organic fiber spinners (24) to establish one or more downwardly moving veils (38) of organic fibers (34) positioned above the collecting surface (12), the veils (22) of mineral fibers (16) being generally collinear with the veils (38) of organic fibers (34), the veils (38) of organic fibers (34) alternating with the veils (22) of mineral fibers (16) to integrate the organic material and the mineral fibers (16), and collecting the integrated organic material and mineral fibers (44) on the collecting surface (12).
