大侧基氨基酸含量对蚕丝织品老化状况的表征研究

Study on Representation of Amino Acid Content with Bulky-side Groups on Aging Degree of Silk Fabrics

为探求氨基酸检测技术在纺织品文物保护方面的应用,利用丝织品氨基酸含量对其劣化程度进行评估。对光老化处理丝织品分别进行拉伸断裂强力和氨基酸含量测试,分析其大侧基氨基酸含量与断裂强力保留率之间的关系,用得到的数据统计图来预估出土于浙江安吉、新疆、江西南昌三地不同时期的丝织品文物的劣化情况。将丝织品文物的氨基酸表征结果与其纤维横截面形貌状况作对比分析,证实了大侧基氨基酸含量对丝织品文物劣化状况有较好的表征效果。

In order to explore the application of amino acid detecting technology in protection of textile cultural relics,the study of amino acid content of silk fabrics on the deterioration degree was evaluated.Tensile breaking force and amino acid content testing were conducted for silk fabrics after light aging treatment.The relationship between breaking force retention rate and amino acid content with bulky-side group was analyzed.The data statistics gained was used to predict degradation of silk fabric cultural relics unearthed from Anji in Zhejiang,Xingjiang,Nanchang in JiangXi.The contrastive analysis of amino acid representation result of silk fabric cultural relic and cross-section morphology of the fiber proved that amino acid content with bulky-side group had good representation effect on degradation of silk fabric cultural relic.
