摘要
Abstract
The cellulose/1-ethyl-3-methylimidazolium acetate （[EMIM]Ac） solution was prepared by using the ionic liquid-[EMIM]Ac as the solvent, the rheological behaviour of the solution was investigated. The dry-jet spinning was used to prepare regenerated cellulose fiber and the structure and properties were studied. The results showed that cellulose/[EMIM]Ac solution belonged to the typical shear thinning fluid, and the apparent viscosity of solution was barely changed when the shear rate was high, the prepared fiber had cellulose II crystal structure, and the orientation and crystallinity of fiber increased with the increasing of draw ratio, thereby the mechanical properties of fiber improved. Moreover, the fiber had smooth surface as well as round and compact structure.关键词
