Beschreibung
Zusammenfassung:	A flooring felt, which exhibits dimensional stability and is well suited for use in the production of floor coverings, is produced by removing water from an aqueous furnish composition comprising glass fibers, a rubber binder, cellulose pulp, fibrillated synthetic fibers, an inorganic filler, a soluble aluminum, ferric or stannic salt, and a sufficient amount of an alkaline hydroxide to provide a furnish pH within the range from about 6 to about 10, said alkaline hydroxide serving to convert the soluble salt to a water-insoluble hydroxide.
