Cysteine reinforcement method for rotten silk cultural relics

Abstract

The invention relates to a cysteine reinforcement method for rotten silk cultural relics, which is characterized by comprising the following steps: A), preparing L-cysteine aqueous solution with the mass percentage concentration being 2.5 percent; and B), adopting a spraying method to spray the cysteine aqueous solution onto surfaces of the rotten silk cultural relics until the rotten silk cultural relics are uniformly wetted by the cysteine aqueous solution and water drops down, and naturally drying the rotten silk cultural relics, thereby reinforcing the rotten silk cultural relics. Compared with the prior art, the method has the advantages that: 1) the operation is convenient; 2) other chemical additives are not needed except cysteine, the breaking strength and breaking elongation of weak silk can be significantly improved after reinforcement, and no negative impact can be produced on the cultural relics.

Description

technical field [0001] The invention relates to a method for protecting silk cultural relics, in particular to a cysteine ​​reinforcement method for decayed silk cultural relics. Background technique [0002] Silk is a natural high-molecular protein, which is easily degraded or destroyed by many factors such as water, light, heat, oxygen, acid, alkali, and microorganisms, resulting in a large number of molecular bonds in silk fibers being broken, and the result is inevitable. It is the strength of silk fiber that is greatly reduced. How to effectively strengthen and protect silk cultural relics that are on the verge of destruction, and develop new methods for strengthening and protecting silk cultural relics are urgent and important research topics in the field of cultural relics. [0003] The Silk Protein Reinforcement Project, a collaboration between Zhejiang Sci-Tech University and the China National Silk Museum, developed research on silk fibroin reinforcement of fragil...

AI Technical Summary

Problems solved by technology

However, the preparation of silk fibroin solution is cumbersome and difficult to store and transport. Second, people hope to have a reinforcement method that does not require other chemical additives.
