Study on Increasing Strength of Silkworm Silk

Abstract:

In this paper, the raw silks were soaked in NaSCN solution, and drown to increase the broken strength. The result showed that after the raw silk was in NaSCN solution, the silk could be drown 1.46 times. The broken strength of the drown silk increased greatly. But the broken elongation decreased greatly. The washing process could increase the broken strength of drown silk. After the drown silk was washed with worm pure water, the broken strength of the drown silk could reached to 0.72 GPa, and the broken elongation recovered very well. The FT-IR spectra, DSC and X-ray diffraction spectra showed the drown silk has more oriented β-sheet crystalline structure, and the thermal decomposition temperature of drown silk increased 10 oC than normal silk. The results showed drowing silk is an efficient method to increase the strength of the silkworm silk.
