Comparison of the Spinning Performance of Cellulose/BMIMCl Solutions Prepared by Direct Dissolving Process and Two Steps Processes
Cellulose is the most common organic polymer on the Earth and is regarded as an almost inexhaustible source of raw materials. So effective use of cellulose not only reduces the consumption of the limited fossil resources but also protects the environment of the Earth. Starting with dissolution of pulp as a purified raw material, cellulose is changed by large-scale industrial processing into regenerated materials (fibers, paper, food casings, membranes, sponges, and among others) and cellulose derivatives (ethers and esters). However, processing and derivatization of cellulose are very difficult in general, because this natural polymer is neither meltable nor soluble in conventional solvents due to its hydrogen bonded and partially crystalline structure1-2 So present industrial production of regenerated cellulose and cellulose derivatives are in long time dominated by polluting viscose process and heterogeneous processes, respectively In recent years, the dissolution of cellulose in ionic liquid, especially in l-butyl-3-methylimidazolium chloride (BMIMC1) is studied a lot by many people3-9.
