摘要:
   应用二阶导数红外光谱定量计算法库县叶茂台出土的辽代丝绸和现代蚕丝蛋白分子构象的百分比,分析辽代蚕丝分子构象的变化原因,并结合X-射线衍射结果讨论了辽代丝绸的老化特征。分析结果说明,辽代蚕丝蛋白无规构象比β-折叠链降解速度快,致使辽代蚕丝纤维结晶度高于现代蚕丝,由此解释了古代蚕丝结晶度比现代蚕丝还要高的原因,为古代丝绸保护提供了一定的科学依据。
Abstract:
 Wi th the appl icat ion of the second derivat ive Infrared Spectra to calculate quant i tat ively the percentage of modern silk and the Liao Dynasty silk conformation unearthed from Yemaotai in Faku county, the reason of the changes was analyzed, combined with the X-ray diffraction result to discuss the degradation characteristics of the Liao Dynasty silk. Infrared spectrum showed that the degradation of random chains was faster than β-sheet chains, resulting in higher crystallinity of the Liao Dynasty silk fiber than the modern silk, which can explain the crystallinity of ancient silks is even higher than modern silks and provide some scientific basis for the protection of ancient silks.
