Abstract
Method of producing a nonwoven material by hydroentangling of a fiber web, whereby dry fibers, natural and/or synthetic, are metered into a dispersion vessel, possibly after pre-wetting. The fibers are dispersed in a foamable liquid including water and a tenside for forming a foamed fiber dispersion, which is applied to a wire and drained. The formed fiber 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.
