Problems solved by technology

When archaeologists took out the textiles from the tomb, due to human movement and changes in the environment, etc., wool fabrics are very prone to ash and breakage
If these precious unearthed cultural relics are not effectively strengthened and protected, they will be easily damaged

Abstract

The invention relates to a keratin homologous reinforcement method of fragile wool fabric. Keratin is extracted from wool with sodium hydroxide and hydrogen peroxide; the obtained solution is dialyzed and freeze-dried to prepare keratin powder; fragile wool fabric is dipped in the keratin solution for a period of time, is dipped into a tyrosinase solution to be treated for a certain period of time, and is aired at room temperature, so as to obtain reinforced fragile wool fabric. Compared with the prior art, the keratin homologous reinforcement method has the beneficial effects that (1) the keratin and the wool fabric are subjected to cross-linking reaction under the catalysis action of tyrosinase, so that the strength of the fragile wool fabric is relatively greatly improved; (2) the appearances of wood fabric cultural objects are preserved, and meanwhile, the strength and the compliance of the fragile wool fabric are greatly improved; (3) the tyrosinase has excellent biocompatibility, is small in damages to the wool fabric, and beneficial to softening and protecting of the fabric; and (4) the method is simple, and is simple and convenient to operate.

Description

technical field [0001] The invention relates to a keratin homologous reinforcement method for fragile wool fabrics, belonging to the technical field of cultural relics protection. Background technique [0002] my country is an ancient civilization with a long history, and the ancients have left us a rich material cultural heritage. Among them, as the carrier of culture, cultural relics are preserved and passed down in the form of physical objects. These precious cultural relics are not only records of history and culture, but also play an important role in scientific research and artistic value. Wool fabrics are buried underground, and under the influence of temperature, humidity, acidity and alkalinity of the soil, bacteria, mold, etc., the protein fibers are easily aged and degraded. During the aging process of wool fabric, the polypeptide chain breaks and the crystallinity decreases, resulting in changes in the physical properties (such as tensile strength, elongation, ...
