【摘要】 新疆地区属于典型大陆性气候区域,昼夜温差大、地下水循环蒸发、丰富的盐类等因素加速了羊毛劣化。对新疆小河墓地出土羊毛文物进行分析检测,采用高温水处理老化方式模拟羊毛劣化过程,从形貌、亲水性、红外、X射线衍射及氨基酸进行分析。结果显示:随老化时间增加,羊毛鳞片层遭受破坏,纤维横截面出现裂纹、缺损,纤维直径缩小,疏水性减弱,胱氨酸及结晶区破坏严重,造成羊毛强度下降。更多还原

【Abstract】 Xinjiang belongs to the typical continental climate zone.The huge temperature difference between day and night,groundwater circulation evaporation,rich salts and other factors accelerate the degradation of wool.Wool cultural relic unearthed from Xiaohe Tomb in Xinjiang was analyzed and detected.High-temperature water treatment was used to stimulate degradation process of wool.The analysis was carried out from the following aspects:morphology,hydrophily,FT-IR,X ray diffraction and amino acid.The results show that as ageing time increases,scale layer of wool is damaged;crack and defect occur on the cross section of fiber;fiber diameter reduces,and hydrophobicity weakens;cystine and crystalline region are seriously damaged,which results in the drop of wool strength.更多还原
