Abstract:
A method for manufacturing a mineral fiber product includes centrifuging mineral fibers with a spinner, forming a veil of the mineral fibers moving in the direction of the axis of the spinner, directing toward the veil, from a position within the veil, organic material to cause intermingling of the organic material and the mineral fibers, and, collecting the intermingled organic material and mineral fibers to form a mineral fiber product.

Abstract:
A method for manufacturing a mineral fiber product includes establishing a stream of mineral fibers, directing polymeric fibers toward the stream of mineral fibers to cause intermingling of the polymeric material, and applying heat to the polymer fibers so that some of them become softened to the extent that they lose their fibrous form and become attached to the mineral fibers as non-fibrous particles, whereas some of the polymer fibers retain their fibrous form.
