Abstract
Insulating materials consisting of artificial mineral fibers are impregnated with water insoluble additives, e.g. dust binders and/or water repellant finishing agents in that they are wetted with an emulsion of the water insoluble additive in an aqueous solution of a cellulose ether. Impregnation takes place easily and is effective and resistant.
