Secondly, spinnability of SF dope was studied. The results indicated that the higher concentration of the dope and the less content of H2O would result in the better spinnability. And higher concentration of the dope had good spinnability whether the dissolution system containing minim EDTA or not. Pure EtOH and LiBr/EtOH (40/60, w/w) were used as solvent, to which minim EDTA was added. Then certain degummed SF was dissolved in the above mixed solvents to prepare the dope (21.7wt%) containing minim EDTA or not, respectively.
