Polyacrylonitrile (PAN), cellulose acetate (CA) and polyacrylonitrile - cellulose acetate (PAN-CA) fibres were formed in single and binary solvents which were subjected to gyration under pressure. Fibres in the diameter range 200–2000nm were generated using a rotating speed of 36,000rpm and a working pressure of 3×105Pa. Long fibre morphologies with isotropic distribution of fibre orientation were...
