Abstract

A sort of manufacturing method of LYOCELL monofilaments wherein a solution of cellulose in a aqueous tertiary amine N-oxide solvent is extruded from a spinnerette through a gaseous gap into a coagulating bath, at least one stream of gas generally transversely to the filaments, the method being characterized in that: (a) the length of the gaseous gap is in the range from 20 to 200 (b the spinning speed of the filaments is in the range from 5 to 50; (c) the residence time of the filament in the gaseous gap is in the range from 150 to 500ms; (d) he velocity of the stream of gas or at least one of the streams of gas supplied into the gaseous gap is in the range from 1 to 20; (e) the moisture content of the steam or streams of gas referred to in (d) is in the range from 7 to 15 g/kg; and (f) the product of said residence time in ms and said moisture content in g/kg is in the range from 1200 to 7200 ms.g/kg.
