Problems solved by technology

[0003] At present, the simulation research on the aging methods of printed and painted silk cultural relics mainly focuses on ultraviolet aging, light and humidity aging, heat aging, and microbial aging. In the study of fibers, there is no research on the pigment layer on the surface of the cultural relics, the protective layer on the surface of the pigment layer on the aging of enzymes, nor the influence of the pigment layer on the enzyme activity.

Abstract

The invention relates to the field of relic protection, and discloses a method for simulating enzyme ageing of printing and drawing type silk relics in tombs. The method comprises steps as follows: (1) antique printing and drawing silk fabric is treated with a solution A, washed with deionized water, subjected to ultraviolet sterilization treatment for 30-50 min after being air-dried and sheared into small pieces B; (2) 800-1,000 parts by mass of a buffer solution are prepared, 1 / 10000-2 / 10000 parts by mass of pronase from streptomyces gris are added, then, an enzyme promoter is added, and a solution C is prepared; (3) B is completely soaked in the solution C and continuously aged in a sterile incubator at 38+ / -1 DEG C, and an enzyme ageing sample simulating the printing and drawing type silk relics in tombs can be obtained after 40-60 days. Through integration of multiple factors of enzyme for ageing of the relics, the enzyme ageing mode of the printing and drawing type silk relics in tombs can be effectively simulated, and a very important role is played on research of the enzyme ageing mechanism of the printing and drawing type silk relics and protection of relics.

Description

technical field [0001] The invention relates to the field of cultural relics protection, in particular to an enzymatic aging method for imitating printed and painted silk cultural relics in tombs. Background technique [0002] Printed and painted silk relics are the main carrier of Chinese traditional culture, and the extant parts are excavated from tombs. Because it is buried under the ground all the year round, the fiber will be degraded to varying degrees under the influence of temperature, humidity, soil acidity and alkalinity, bacteria, mold, etc., especially when it is in a humid environment, bacteria and mold will multiply in large numbers. Proteases such as pronase produced can cause devastating damage to cultural relics. Therefore, the protection of printed and painted silk cultural relics is imminent. Since the number of unearthed cultural relics is rare and they are very precious as precious physical witnesses of the history of civilization of the Chinese nation...
