摘要:

为更加有效地利用纤维素与蛋白质资源,采用干喷湿法纺丝方法,以1?丁基?3?甲基咪唑氯盐为共溶剂、乙醇为凝固剂制备了纤维素/ 丝素蛋白共混纤维。研究了喷丝头牵伸与塑化牵伸的倍率分配对纤维分子结构、相形态和力学性能的影响。结果表明:以纤维素为基体的纤维素/丝素蛋白共混纤维的相形态为单相连续结构;当喷丝
头牵伸倍率为3 时,丝素蛋白沿纤维轴向连续分布,其相形态呈微纤状;当喷丝头牵伸倍数增加至5 时,丝素蛋白沿纤维轴向分布出现正弦波动,其相形态呈藕节状;增加塑化浴拉伸工艺可减少纤维成形过程中丝素蛋白的流失;当喷丝头牵伸倍数为5,塑化浴拉伸倍数为1 时,共混纤维的断裂强度达到389.9 MPa,超过常规粘胶纤维。

Abstract:

In order to utilize cellulose and protein resources effectively, the cellulose/silk fibroin blend fiber was fabricated by dry-jet wet spinning method using ionic liquid as solvent. The influence of draw ratio distribution of jet stretch and plastic stretch on the molecular structure, phase morphology and property was strdied. The results show that cellulose is in continuous phase and silk fibroin is in dispersed phase for the cellulose based blend fiber. When the drawing ratio is 3, silk fibroin is fibril like along the fiber axis continuously. When the drawing ratio increases to 5, the dispersion of silk fibroin along the fiber axis shows sine wave and the phase morphology is lotrs rhizome node-like. The weight loss of silk fibroin decreases by virtue of plastification bath drawing. When the drawing ratio is 5 and the plastification bath drawing ratio is 1, the tensile strength of cellulose/silk fibroin reaches to 389.8 MPa, which is higher than that of commercial viscose fiber.

Key words: cellulose, silk fibroin, blend fiber, phase morphology, drawing ratio
