Embodiment 1

[0012] Embodiment 1: a kind of protein-TG enzyme reinforcement method of fragile wool fabric, comprises the following steps:

[0013] 1) According to the ratio of using 2ml solution per square centimeter of fragile woolen fabrics, place the fragile woolen fabrics in a keratin solution with a mass percentage of 0.1%, soak them at 30°C for 60 minutes and take them out;

[0014] 2) According to the ratio of using 2ml of solution per square centimeter of fragile woolen fabrics, place the fragile woolen fabrics obtained in 1) in glutamine with a concentration of 2% (w / v, in g / L) and an enzyme activity of 100u / g In the amide transaminase solution, soak for 120 minutes at a temperature of 45°C and a pH value of 5.0, take it out, lay it flat, and react at a temperature of 50°C for 8 hours;

[0015] 3) Wash the above-mentioned fragile woolen fabric for 3 times, spread it flat, and dry it in the shade to obtain the fragile woolen fabric treated with keratin-TG enzyme reinforcement.

Embodiment 2

[0016] Embodiment 2: a kind of protein-TG enzyme reinforcement method of fragile wool fabric, comprises the following steps:

[0017] 1) According to the ratio of using 2ml of solution per square centimeter of fragile woolen fabrics, place fragile woolen fabrics in a keratin solution with a mass percentage of 5%, soak them at 30°C for 120 minutes and take them out;

[0018] 2) According to the ratio of using 2ml of solution per square centimeter of fragile woolen fabrics, place the fragile woolen fabrics obtained in 1) in glutamine with a concentration of 20% (w / v, in g / L) and an enzyme activity of 100u / g In the amide transaminase solution, soak for 60 minutes at a temperature of 55°C and a pH value of 7.0, take it out, spread it flat, and react at a temperature of 60°C for 4 hours;

[0019] 3) Wash the above-mentioned fragile woolen fabric for 3 times, spread it flat, and dry it in the shade to obtain the fragile woolen fabric treated with keratin-TG enzyme reinforcement.

Embodiment 3

[0020] Embodiment 3: a kind of protein-TG enzyme reinforcement method of fragile wool fabric, comprises the following steps:

[0021] 1) According to the ratio of using 2ml of solution per square centimeter of fragile woolen fabrics, place the fragile woolen fabrics in a keratin solution with a mass percentage of 2.5%, soak them at 25°C for 90 minutes and take them out;

[0022] 2) According to the ratio of using 2ml of solution per square centimeter of fragile woolen fabrics, place the fragile woolen fabrics obtained in 1) in glutamine with a concentration of 10% (w / v, in g / L) and an enzyme activity of 100u / g In the amide transaminase solution, soak for 90 minutes at a temperature of 50°C and a pH value of 6.0, take it out, spread it flat, and react at a temperature of 55°C for 6 hours;

[0023] 3) Wash the above-mentioned fragile woolen fabric for 3 times, spread it flat, and dry it in the shade to obtain the fragile woolen fabric treated with keratin-TG enzyme reinforcement...

Abstract

The invention relates to a protein-transglutaminase (TG) reinforcement method of fragile wool fabrics. The method comprises the steps of firstly, dipping the fragile wool fabrics into a keratin solution; dipping the fragile wool fabrics into a TG solution; spreading out the dipped fragile wool fabrics, and carrying out reaction on the fragile wool fabrics for 8-4h at the temperature of 50-60 DEG C; finally, washing the fragile wool fabrics for three times by water, spreading out the washed fragile wool fabrics, and drying the wool fabrics at a shade place. The protein-TG reinforcement method has the beneficial effects that under the help of microbial transglutaminase (MTG), keratin is used for reinforcing the fractured polypeptide chains, so that the appearances of wool fabric cultural relics are not influenced, and the method has prominent superiority in the aspect of high temperature aging resistance.

Description

technical field [0001] The invention relates to the technical field of cultural relics protection, and relates to a reinforcement method for fragile wool fabrics, in particular a protein-TG enzyme reinforcement method for fragile wool fabrics. Background technique [0002] Ancient woolen fabrics are an important part of my country's cultural treasure house, and the reinforcement of unearthed fragile woolen fabrics has always been an important topic explored by cultural relics protection workers. Since the main component of woolen fabric cultural relics is protein, it is very easy to be degraded by acid, alkali, salt, etc. during the burial process and the strength will be reduced. The aging of wool fabrics makes the fibers of wool fabrics weaker and the mechanical strength is reduced. Some unearthed woolen fabrics became hard and brittle, some were broken, and some could not withstand handling and would break if touched, making it difficult to preserve woolen fabric cultura...
