| 主权项 | 1. A process for the production of a hydroentangled product comprising fibers, wherein the fibers consist essentially of fibers obtained from cellulose dissolved in an aqueous tertiary amine-oxide, said process comprising subjecting a Lyocell melt-blown web to a treatment by fine high-pressure jets of water, the improvement wherein the web is subjected to said fine high-pressure jets in at least three treatment steps, wherein the pressure of said high-pressure jets is 75 bar or less in each of said treatment steps. | ||
