摘要
丝织品生物加固法相较于传统加固方法具有天然高效、对本体影响小等优点。文中以家蚕中部丝腺提取物为加固材料,利用其组分与丝织品接近,具有较高兼容性等特点,采用木瓜蛋白酶进行改性后加固模拟老化样品。通过测试样品力学性能、微观物相结构、热稳定性、微观形貌等,证明了加固材料可有效附着在丝织品表面,加固后样品具有更高的力学性能,同时本体微观结构所受影响较小。通过测定可溶性丝蛋白含量及用电镜观察微观孔隙,证明了加固材料可以通过填补样品微观孔隙与结构空缺,在宏观上起到加固效果。该研究探析了一种丝织品生物加固方法,扩展了丝织品文物保护材料的选择范围。
Compared to traditional reinforcement methods,the biological reinforcement method for silk fabrics has the advantages of natural efficiency and minimal impact on the body.In the experiment,the extract from middle silkgland of silkworm was selected as the reinforcement material.As its composition was similar to that of silk fabrics and had high compatibility,papain was used to modify and apply to the reinforcement of simulated aging samples.By testing the mechanical properties,micro phase structure,thermal stability,and micro morphology of samples,it was proven that the reinforcement material effectively adhered to the surface of silk fabrics,and the reinforced sample had higher mechanical properties.At the same time,the impact on the microstructure of the body was relatively small.Through the measurement of soluble silk protein content and electron micro pores observation,it was proven that the reinforcement material could fill the micro pores and structural gaps in the sample,the reinforcement effect had been achieved at the macro level.The experiment explored a biological reinforcement method for silk fabrics,expanding the selection range of materials for protecting silk cultural relics.
