摘要：

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 studied. 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 lotus 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.
