摘要/Abstract

摘要：

为探究湿、热环境对丝织品文物保存状况的影响,在110、130 ℃条件下分别对桑蚕丝试样进行干热老化和湿热老化模拟实验。借助万能材料试验机、色度计、扫描电子显微镜和傅里叶红外光谱仪对老化前后试样的抗拉强度、颜色、微观形貌和结构进行了分析。同时,提出了丝织品的寿命预测方程。结果表明:试样强度随老化时间呈线性下降,颜色变黄;干热老化和湿热老化后,纤维表面出现不同程度的破坏,且湿热老化后,纤维束交织形成的孔洞周围较其他部位溶蚀显著;纤维二级结构中β-折叠构象含量显著降低,与强度变化趋势一致;低温、干燥条件适于丝织品文物的保存。

Abstract:

In order to investigate the influence of wet and thermal environments on the preservation of silk cultural relics, silk (Bombyx mori) samples were aged by dry heat and damp heat at 110 ℃ and 130 ℃, respectively. Material testing machine, colorimeter, scanning electron microscope and Fourier transform infrared spectrometer were used to measure and analyze the tensile strength, color, micro-morphology and structure of simulated silk samples before and after aging. The life prediction equation of silk fabrics was proposed. The results show that the tensile strength of the samples decrease linearly with the aging time, while the color turned yellow. After dry heat and damp heat aging, the fiber surfaces show different degrees of damage, and in the latter condition pores formed by fiber bundle interlacing are more significantly corroded than other parts. The content of β-sheet in the secondary structure is significantly reduced, consistent with the trend of strength change. The work reveals that the low temperature and dry condition are suitable for the preservation of silk cultural relics.

Key words: silk fabric, dry heat aging, damp heat aging, life prediction, preservation of cultural relics
