Ionic liquid as novel solvent in application of preparation of high-value added cellulose fibers

In order to explore the development of high value added cellulose fibers,the paper makes a review of the application of ionic liquids as a novel solvent in the preparation of high value added cellulose fibers,including the ionic liquid solvent system,and the spinning process and technological progress,and pointing out that based on rather mature theoretical research and accumulation of related technology,and the use of ionic liquids as a novel solvent in the preparation of cellulose fibers is now in the early phase of engineering. Many kinds of high value added cellulose fibers prepared using ionic liquid as a solvent have been listed. It is proposed that the development of high value added composite cellulose fibers and cellulose derivation fibers should be the direction of applied research of ionic liquids.
