Embodiment 1

[0011] Embodiment 1: a keratin reinforcement process for fragile wool fabrics on the site of unearthed cultural relics, comprising the following steps:

[0012] 1) Add wool fiber to a mixed solution containing 1% by mass of 2-mercaptoethanol and 3mol / L urea, place it in an ultrasonic wave for 0.5 hours at a temperature of 60°C, and then filter the undissolved wool fiber , the remaining solution was put into a dialysis bag with a molecular weight cut-off of 12,000, and the dialysis bag was placed in deionized water for dialysis for 2 days, and the deionized water was changed every 12 hours, and then the obtained dialysate was freeze-dried to obtain keratin powder for use;

[0013] 2) Prepare the keratin powder obtained in 1) into a keratin solution with a mass percentage of 1%, spray evenly on the fragile wool fabric, and dry in the shade;

[0014] 3) Adjust the pH value of the ethylene glycol diglycidyl ether solution to 6.3, and evenly spray the above-mentioned ethylene glyco...

Embodiment 2

[0015] Embodiment 2: a keratin reinforcement process for fragile wool fabrics on the site of unearthed cultural relics, comprising the following steps:

[0016] 1) Add wool fiber to a mixed solution containing 5% by mass of 2-mercaptoethanol and 7mol / L urea, place it in an ultrasonic wave for 2 hours at a temperature of 100°C, and then filter the undissolved wool fiber , the remaining solution was put into a dialysis bag with a molecular weight cut-off of 14000, the dialysis bag was placed in deionized water for dialysis for 2 days, and the deionized water was changed every 12 hours, and then the obtained dialysate was freeze-dried to obtain keratin powder for later use;

[0017] 2) Prepare the keratin powder obtained in 1) into a keratin solution with a mass percentage of 5%, spray evenly on the fragile wool fabric, and dry in the shade;

Abstract

The invention relates to a keratin reinforcement technology for fragile wool fabrics in a cultural relic excavation site. The technology comprises the steps of extracting keratin from wool fibers to prepare keratin powder; preparing a keratin powder solution, evenly spraying the keratin powder solution onto the unearthed fragile wool fabrics, and drying the fragile wool fabrics at a shade place; evenly spraying an ethylene glycol diglycidyl ether (EGDE) solution onto the treated fragile wool fabrics, and wetting the fragile wool fabrics completely for ten hours; washing the wool fabrics by clear water, and naturally drying the wool fabrics. The keratin reinforcement technology has the beneficial effects of being simple and easy and convenient to operate; the properties of the wool fabric cultural relics are not influenced by using the technical process, and the integration of the appearances of the wool fabric cultural relics can be guaranteed; the breaking strength and the softness of the reinforced wool fabrics are greatly improved.

Description

technical field [0001] The invention relates to the technical field of cultural relics protection, in particular to a rescue keratin reinforcement process for fragile wool fabrics at the site of unearthed cultural relics. Background technique [0002] Wool fabric, as a kind of natural fiber, was widely used in clothing and blankets in the ancient northern region, of which wool fabric accounted for the majority. A large number of unearthed wool fabrics are as exquisite as the unearthed silk cultural relics. This is not only an important physical evidence of the evolution of ancient textile technology, but also has important reference value for the study of ancient social environment and human activities. [0003] Wool is a natural protein fiber, a natural polymer material made of amino acids connected by peptide bonds, so it is vulnerable to the influence of the buried environment, such as temperature, humidity, soil acidity and alkalinity, bacteria, etc., and begins to age a...
