Abstract
Dissolution of Antheraea pernyi silk fiber was carried out in a zinc chloride solution with various dissolving conditions. The solubility was significantly dependent on the concentration of zinc chloride, dissolving temperature and time. The proper conditions of dissolution were found as 8 M zinc chloride, 70$^{\circ}C$ temperature and 30 min dissolving time. Regenerated A. pernyi silk fibroin powder was obtained through dialysis. FTIR and XRD showed that regenerated A. pernyi silk powder was composed of a ${\beta}$-sheet as well as an ${\alpha}$-helix conformation.
