Problems solved by technology

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

Embodiment 1

[0013] Embodiment 1, the fibroin molecular reinforcement method of the fragile silk of the present invention, it adopts the following steps:

[0014] A) The fragile silk is placed in a 1% by weight silk protein solution at a weight ratio of 1:100, soaked at 26° C. for 1 hour, taken out, and allowed to dry naturally;

[0015] B) Put the fragile silk into 0.01% by weight aqueous solution of ethylene glycol diglycidyl ether, soak it at 28° C. for 1 hour and take it out;

[0016] C) Curing the fragile silk after the above treatment at 40°C for 12 hours;

[0017] D) After drying naturally, the silk reinforced by fibroin molecules is obtained.

[0018] The silk fibroin solution is a silk fibroin solution.

Embodiment 2

[0019] Embodiment 2, the fibroin molecular reinforcement method of the fragile silk of the present invention, it adopts the following steps:

[0020] A) The fragile silk is placed in a 0.1% by weight silk protein solution at a weight ratio of 1:30, soaked at 20° C. for 1 minute, taken out, and allowed to dry naturally;

[0021] B) Put the fragile silk into the aqueous solution of ethylene glycol diglycidyl ether with a concentration of 0.001% by weight, and take it out after soaking at 20°C for 1 minute;

[0022] C) curing the fragile silk after the above treatment at 20°C for 2 hours;

[0023] D) After drying naturally, the silk reinforced by fibroin molecules is obtained.

Embodiment 3

[0024] Embodiment 3, the fibroin molecular reinforcement method of the fragile silk of the present invention, it adopts the following steps:

[0025] A) The fragile silk is placed in a 5% by weight silk protein solution at a weight ratio of 1:200, soaked at 35° C. for 2 hours, taken out, and allowed to dry naturally;

[0026] B) Put the fragile silk into the aqueous solution of ethylene glycol diglycidyl ether with a concentration of 10% by weight, and take it out after soaking at 35° C. for 2 hours;

[0027] C) Curing the fragile silk after the above treatment at 60°C for 24 hours;

[0028] D) After drying naturally, the silk reinforced by fibroin molecules is obtained.

Abstract

The invention provides a silk protein reinforcing method for fragile silk, comprising the steps as follows: A) the fragile silk with the weight ratio of 1:30-200 is put in a silk protein solution with the weight percentage of 0.1-5% and dipped for 1min to 2h at the temperature of 20-35 DEG C and then taken out and naturally dried; B) the fragile silk is put in ethylene glycol diglycidyl ether solution with the weight percentage of 0.001-10%, dipped for 1min to 2h at the temperature of 20-35 DEG C and then taken out; C) after the treatment, the fragile silk is solidified for 24h to 2h at the temperature of 20-60 DEG C; and D) after natural drying, the silk reinforced by the silk protein molecular is obtained. The method has the advantages of simple method, convenient operation, not affecting the appearance of the silk relic, partly recovering the true luster of the relic, having outstanding advantages on high-temperature ageing resistance, and the like.

Description

technical field [0001] The invention relates to a fibroin reinforcement method 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, microorganisms, etc. will cause denaturation of silk protein and breakage of macromolecular chains, making silk fibers fragile and easy to break, and the mechanical strength is obviously reduced. [0003] In the past, the reinforcement and protection of silk cultural relics at home and abroad mainly included weaving reinforcement method, mounting m...
