ABSTRACT:
Disclosed is a method of producing a low density fibrous composition that is suitable for use as an insulation material. The method comprises first forming an aqueous mixture comprising fibers and a synthetic rubber binder for the fibers and a foamed detergent to a consistency ranging from about 4 to about 15 weight percent solids. The mixture is then foamed to homogeneously suspend all of its components therein and then dried to form the low density fibrous composition.
