Abstract (en)
[origin: WO9746745A1] The invention concerns a method of producing a cellulosic yarn by spinning a solution of cellulose in a tertiary amine oxide to form fibres or filaments, the cellulose solution optionally still containing water and optionally containing a stabilizer and being precipitated, washed and dried. Before drying, the yarns are treated for fewer than 20 seconds with an aqueous alkali solution.
