2. Method as claimed in claim 1, wherein the textile auxiliary is introduced into the system of the hydrodynamic solidification by means of a dosing pump.
3. Method as claimed in claim 1 wherein two or more non-solidified or pre-solidified nonwoven fabrics are bonded to each other.
4. Method as claimed in claim 1, wherein the nonwoven fabric to be solidified or the nonwoven fabrics to be bonded are comprised of synthetic materials, such as polypropylene, polyethylene, polyamide or polyester, or of mixtures thereof.
5. Method as claimed in claim 1, wherein the nonwoven fabric to be solidified or the nonwoven fabrics to be bonded are comprised of or include bi-component fibers.
6. Method as claimed in claim 1 wherein the nonwoven fabric(s) additionally contain natural fibers.
7. Geotextiles solidified according to claim 1.
