利用X射线衍射光谱研究丝织品的老化

中国考古出土的丝织品数量大，种类丰富，是中国古代文化遗产的重要组成部分，但由于丝蛋白易于降解老化的材料特性，有许多保护问题需要研究解决。对古代丝织品老化程度、老化特征的分析检测有助于了解丝织品的保存状况，并可为保护方法的选择与改进提供帮助。文章通过X射线衍射分析对丝织品老化特征及结晶度的变化进行了研究。样品为经光老化、热老化和水解老化的白色丝织品和出土于湖北、陕西、内蒙古、青海的古代丝织品。X射线衍射分析结果表明，X射线衍射分析可以揭示丝织品的老化作用过程和老化特征，以及相应结晶度的变化，对于出土古代丝织品保存状况及老化机理的研究来说具有实用价值。同时还可为了解古代染织工艺的发展提供信息。

Research on the Silk Aging with X-Ray Diffraction Spectra

The present paper did some researches on the deterioration mechanism and the changes in crystallinity of silk fabrics by means of the X-ray diffraction analysis.The samples artificially aged and excavated from Hubei,Innermongolia,Shaanxi and Qinghai provinces were analyzed.The artificial aging was done by simulating three main natural aging factors:light,heat and hydrolysis.The analytical results show that X-ray diffraction analysis could reveal the aging process and characteristic of silk,as well as the ch...
