PROCESS FOR THE PRODUCTION OF SHAPED CELLULOSE ARTICLES

摘要

A method of manufacturing a cellulose-based shaped article. The method comprises subjecting a solution of lignocellulosic material, dissolved in a distillable ionic liquid, to a spinning method,wherein the ionic liquid is a diazabicyclononene (DBN)-based ionic liquid. DBN-based ionic liquids have good dissolution power, high thermal and chemical stability, lack runaway reactions and exhibit low energy consumption, due to low spinning temperatures. The shaped cellulose articles can be used as textile fibres, high-end non- woven fibres, technical fibres, films for packaging, and barriers films in batteries, as membranes and as carbon-fibre precursors.
