After the impregnation with the waterproofing agents, the fibrous material is advantageously heated for a short period of time, if necessary in the presence of moisture, for example with the aid of steam, whereby the waterproofing effects are still further improved.
• the waterproofing agents used in the examples below were produced by first dissolving the metal alcoholates in an organic solvent, such as in trichloroethylene or benzene, and thereafter stirring a solution of the high molecular acid phosphoric acid alkyl ester in an identical or similar solvent into the metal alcoholate solution.

The solution mixture was then ready for use in the impregnation step. It may, however, also be admixed with small amounts of a stabilizing agent. The solution mixture was used in the resulting concentration or in a more diluted state, which was achieved by merely adding more of the respective solvent.
