This talk will cover some previous work to better understand structure property relationships of regenerated cellulose fibres [1,2] using Raman spectroscopy and other techniques (X-ray diffraction). Some of the main issues for producing high performance fibres (stiffness, strength) such as the control of orientation and the microstructure will be presented. Some more recent work, funded by the UK's research council (EPSRC) on ionic liquid spinning of cellulose will also be presented. This work will be compared against previous liquid crystalline spun filaments e.g. Bocell [3] and other ionic liquid spun fibres. Prospects for the future will be discussed in light of recent developments in the area. 1. Kong, K. and Eichhorn, S.J. 2005.
