The study of rheological and mechanical properties of the Antarctic krill protein/sodium alginate fibers

摘要：

　　protein was extracted from Antarctic krill(AK), then blended with sodium alginate (SA),prepare the spinning solution, the rheological properties of spinning solution were studied by Brookfield DV-C digital viscosimeter.AKP/SA fibers were prepared via wet spinning with CaCl2 and PEG as coagulator.The morphology, tensile strength and thermal property of AKP/SA fibers were characterized by polarized light microscopy, monofilament strength tester and thermal gravimetric analysis (TGA) instrument.The result shows that the shear viscosities of spinning solution decrease with the increasing of shear rate and decreasing of concentration, the optimal Preparation Process of AKP/SA fibers were 5% concentration of SA, proportion of 1: 9 for AKP solution to SA solution, and proportion of 5:1 for CaCl2 to PEG.The cross-section of AKP/SA fiber is a jagged shape.Thermal property of AKP/SA fibers is similar to SA fibers.
