Effect of methylimidazole on cellulose/ionic liquid solutions and regenerated material therefrom

摘要: Cellulose, especially wood-based cellulose, is increasingly important for making everyday materials such as man-made-regenerated textile fibers, produced via dissolution and subsequent precipitation. In this paper, the effect of cosolvents in ionic liquid-facilitated cellulose discussed. Both microcrystalline dissolving grade hardwood pulp were studied. Three different combination with liquid evaluated using turbidity measurements viscosity. The precursor N-methylimidazole proved to be a promising cosolvent candidate was thus selected further studies together 1-ethyl-3-methylimidazolium acetate. Results show that rate can increased by addition, viscosity significantly reduced. solutions stable over time at room temperature could converted regenerated fibers good mechanical properties airgap spinning traditional wet spinning. Fibers spun from binary solvents exhibited higher crystallinity than neat liquid.
