<p>Method of producing a nonwoven material by hydroentangling of a fibre web, whereby dry fibres, natural and/or synthetic, are metered into a dispersion vessel (111), possibly after pre-wetting, the fibres being dispersed in a foamable liquid comprising water and a tenside, for forming a foamed fibre dispersion, which is applied to a wire (118) and drained. The formed fibre web is subjected to hydroentangling directly after forming and the foamable liquid, after having passed through the wire, is recirculated to the dispersion vessel in a simple closed circuit.</p> |
