Abstract:
The present invention relates to a process for the production of a hydroentangled product comprising cellulose fibers, wherein a Lyocell melt-blown web is subjected to a treatment by fine high-pressure jets of water, characterized in that the web is subjected to said fine high-pressure jets in at least three treatment steps the pressure of said high-pressure jets is 75 bar or less in each of said treatment steps. Furthermore, the invention relates to products obtainable by said products, and uses thereof.
