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.

二、丝素溶液纺丝成型特性，结果表明纺丝液浓度较高及纺丝液中水分含量较少时再生丝素溶液有较好的可纺性，且无论体系中是否含有微量EDTA，较高浓度纺丝液均具有较好的可纺性，因此采用无水EtOH 及LiBr/EtOH (40/60，w/w)作为纺丝溶剂，制得了纺丝液浓度为21.7wt%含微量EDTA 及不含EDTA 的可纺性良好的丝素溶液。
