摘要
目前采用一般的物理加固和化学加固方法对脆弱丝织品进行保护存在着一定的缺陷和限制,为此,本工作利用与丝织品具有同源性和亲和性的丝素蛋白对清代丝织品进行加固保护。清代丝织品在丝素蛋白浓度为1.0%、戊二醛浓度为0.005%、浸渍时间(T1)为40min、浸渍时间(T2)为60min的较优工艺条件下,断裂强力从5.22N提高到10.68N,断裂伸长率从3.24%提高到4.12%,硬挺度略有改变,提高了0.08×10-2mN.m。同时,利用FT-IR、TG和SEM等对加固前后清代丝织品的结构进行了表征。实验结果显示,利用丝素蛋白加固丝织品文物是一种有效的方法,在提高古代丝织品强度的同时,不对丝织品的外观与手感造成影响。
Presently used physical and chemical consolidation method have deficiencies and restrictions for consolidating fragile silk textiles. Fibroin protein, because of its homology and compatibility with silk, has been used to consolidate Qing Dynasty silk. Qing Dynasty silk textiles were treated by 1.0% fibroin protein solution for 40 minutes and then in 0. 005 % glutaraldehyde solution for 60 minutes. The results showed the consolidated textile＇s breaking strength point improved from 5.22N to 10.68N;elongation rate at the breaking point improved from 3.24% to 4. 12% ;and flexural stiffness improved 0.06 × 10 -2 mN · m. FT IR,TG and SEM were used to characterize the textiles before and after the treatment. The experimental results indicated that consolidation of ancient silk textile using fibroin protein is effective. This treatment can improve the intensity of the ancient silk textile while leaving the appearance and feel unchanged.
