摘要(Abstract)：

蛋白质纤维具有光滑柔顺、透气吸湿等优点,然而天然蛋白纤维产量有限。再生蛋白纤维的制备通常采用与其它成纤高分子接枝或共混的方法,有利于提高再生蛋白纤维的断裂强度。选用同为天然高分子的纤维素为基体,以共溶剂溶解纤维素与蛋白质,进而纺丝成形制得力学性能满足要求的纤维素/丝素蛋白共混纤维。为了探究凝固剂组成对纤维素/丝素蛋白共混纤维相形态及性能的影响,选用水、乙醇、乙醇/1-丁基-3-甲基咪唑氯盐([BMIM]Cl)等作为凝固剂。研究发现:乙醇作为凝固剂时,纤维素与丝素蛋白能很好地同时凝固;而当在乙醇凝固浴中加入适量的[BMIM]Cl径向均匀分散。通过对凝固剂组成的调控能有效提升纤维的力学强度。
Protein fibers have many advantages such as smoothness, softness and moisture permeability.However, the production of natural protein fibers which can be directly utilized is limited. For improving the property of regenerated protein fibers, the protein is often to be modified by grafting to synthetic polymer or blending with other polymers. So, the natural polymers including cellulose and silk fibroin are chosen to be dissolved in the common solvent, and it has been proved that the property of blend fiber is good. In order to study the effect of coagulants on phase morphology and property of cellulose/silk fibroin blend fiber,coagulants of water, ethanol, ethanol/1-coagulation bath. The resarch finds that ethanol is effective coagulant for cellulose and silk fibroin, the uniform dispersion of silk fibroin along the radial distribution can be found when [BMIM]Cl is added in ethanol. The tensile strength of the blend fiber can be improved by adjusting coagulation bath composition.
