College of Textile and Clothing Engineering, Soochow University, Suzhou 215021, China) Abstract: Calcium nitrate modified silk fiber was treated by chitosan quaternary ammonium salt (HTCC) solution, and then the changes of surface micro-morphology, the aggregation structure and the mechanical properties among the Bombyx mori silk fiber and calcium nitrate modified silk fiber before and after treated with HTCC solution were compared and analyzed in this paper. The results showed that there were obvious longitudinal strips on the surface of calcium nitrate modified silk fiber treated with HTCC, and internal structure became more closely. In addition, the crystallinity and the thermodynamic stability of calcium nitrate
