The factors affecting the quality of chitin and chitosan fibers were described, including chitin and chitosan quality, solvent for spinning dope and its concentration and coagulation bath.
The results show that spinning and fiber properties are influenced by the concentration of the solvent in the coagulating bath and the temperature of the coagulating bath.
结果表明：凝固浴中溶剂浓度对纺丝过程及纤维强度有重要影响，而凝固浴温度对纤维的影响相对较小；
