Abstract

A method of making lyocell filaments, which comprises drawing a filament from cellulose dissolved in an amine oxide; passing the filament through a regeneration pool containing an aqueous solution including an amine oxide, which comprises at least 60% by weight of a tertiary N-oxide, thereby enabling the filament having a skin/core structure, and washing the filament in an aqueous medium.
