چکیده انگلیسی
In this paper, cellulose/Antarctic krill protein composite fibers were obtained by wet spinning. The raw materials were recyclable cellulose (C) and Antarctic krill protein (AKP), while the solvent was an aqueous solution containing 7Â wt% NaOH and 12Â wt% urea, which is eco-friendly. The fiber was stretched in a coagulation bath containing H2SO4 and Na2SO4. The effects of coagulation at different bath concentrations on the mechanical performance, crystallinity, and morphology of the C/AKP composite fibers were studied systematically. The break strength firstly increased and then decreased with an increase in the concentration of the bath. At a coagulation bath concentration of H2SO2/Na2SO4 (12Â wt%/12Â wt%), the crystallinity was 15.16%. Scanning electron microscopy (SEM) observations revealed the presence of grooves on the fiber surface. The type and percentage of hydrogen bonds in the C/AKP composite fibers were analyzed by Fourier transform infrared spectroscopy (FT-IR). On the basis of the obtained results, we finally optimized the coagulation bath composition and concentration.
