摘要
为避免因加固糟朽丝织品的材料老化而影响丝织品文物安全,采用与糟朽丝织品具有同源性和亲和性的丝素蛋白和助剂戊二醛对其进行加固处理,研究加固前后糟朽丝织品断裂强力、断裂伸长率、硬挺度、吸湿率、色差、耐光耐热性、分子结构、表面形貌等的变化。结果表明,经丝素蛋白和戊二醛处理后,脆弱丝织物的强度提高了2.75 N,断裂伸长率提高了3.05%,柔软性得到改善,耐光、热性能有所提高,但未对织物的外观等其他性能造成大的影响,满足了文物保护"修旧如旧"的要求。
To avoid the risk of damage of silk cultural relics caused by ageing of materials used for its cementing,this study used fibroin protein which has homologous and compatible with silk and glutaraldehyde to cement deteriorated silks.The breaking strength,elongation at break,flexural stiffness,moisture regain,chromatic aberration,thermal and light ageing resistance,molecular structure and surface morphology of the silk before and after cementing were investigated.The results showed that the cemented silk has the breaking strength increased by 2.75 N,elongation at break increased by 3.05%,and the softness,thermal and light aging resistance improved with little influence on its appearance and other properties,thus meeting the requirement on ″the old,such as repair of old″ in preservation of cultural relics.
