  • Process for the production of shaped cellulose articles
    Patent number: 10240259
    Abstract: 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 fibers, high-end non-woven fibers, technical fibers, films for packaging, and barriers films in batteries, as membranes and as carbon-fiber precursors.
