Fibroin reinforcement process of fragile silk

Abstract

The invention discloses a fibroin reinforcement technology for brittle silk, which comprises the following steps: A) a fibroin solution is prepared, a soft brush or an atomizing device is used to evenly brush or spray the fibroin solution on the brittle silk until the silk is evenly soaked by the fibroin solution, and then the silk is naturally dried; B) an ethylene glycol diglycidylether water solution is prepared, the soft brush or the atomizing device is used to evenly brush or spray the ethylene glycol diglycidylether aqueous solution on the brittle silk until the silk is evenly soaked by the ethylene glycol diglycidylether aqueous solution, and the silk is naturally dried; C) step A is repeated for n times, step B is repeated for m times, and the repeated steps can perform repeated treatment according to a mode of AB, ABAB,AABAAAB,AAAABAAAB,etc., wherein n is equal to 0, 1, 2, 3, 4, 5, and m is equal to 0, 1, 2, 3, 4, 5; D) the treated brittle silk is solidified; and E) the reinforced silk is obtained after the treatment. The reinforcement technology has the characteristics that the reinforcement technology has a simple method and simple and convenient operation, can greatly improve the strength of the brittle silk, does not affect the appearance of silk relics, can partially recover the silky luster of the relics, and has outstanding advantages in high temperature resistance and aging resistance and so on.

Description

technical field [0001] The invention relates to a fibroin reinforcement process for fragile silk, which belongs to the technical field of cultural relics protection. Background technique [0002] Silk is a symbol of ancient Chinese culture. A large number of silk cultural relics are unearthed every year in our country. These silk cultural relics span six thousand years and have high historical, archaeological and scientific value. Very important physical data in various aspects. Since silk protein is a biopolymer material, it is easily damaged by various factors. External factors such as water, heat, oxygen, light, acid, alkali, and microorganisms will cause denaturation of silk proteins and breakage of macromolecular chains, making silk fibers fragile and easy to break, and the mechanical strength will decrease significantly. Many silk cultural relics that seemed to be well preserved and brightly colored when unearthed have actually been severely aged and brittle under t...

AI Technical Summary

Problems solved by technology

External factors such as water, heat, oxygen, light, acid, alkali, microorganisms, etc. will cause the denaturation of silk protein and the breakage of macromolecular chains, making silk fibers fragile and easy to break, and the mechanical strength will decrease significantly.

Many silk cultural relics that appeared to be well preserved and brightly colored when unearthed have actually been severely aged and brittle under the joint action of various internal and external factors, that is to say, the silk protein has undergone severe denaturation and accompanied by a large number of If the molecular chain is broken, it will be easily damaged if it cannot be effectively protected.
