Problems solved by technology

[0004] It is not easy to remove exogenous strontium in archaeological textiles. After years of burial and storage, archaeological textiles have a certain degree of decay and are inherently very fragile. Research and treatment methods must be gentle so as not to damage them. Miscellaneous problems increase the difficulty

Embodiment 1

[0038] A method for simulating the removal of exogenous strontium in ancient silk fabrics, using the following steps:

[0039] 1) Weigh 100g of madder root from five provinces of Shaanxi, Henan, Anhui, Guizhou and Guangxi, and weigh 50g after drying. After washing the madder roots with deionized water, soak them separately for about 24 hours with deionized water.

[0040] 2) Put the soaked madder roots separately into the stew pot, boil and refine the dyeing solution. Boil each kind of madder root three times, add 1000ml of water each time, and pour it out when there is about 400ml left. Mix the three extracted dye solutions, pour out the madder root in the pot, wash the stew pot with deionized water, then pour the mixed dye solution into the stew pot for further refining, and pour it out when 1000ml is left. The water used in this process is deionized water. When pouring the dye liquor out of the pot, a piece of silk cloth washed with deionized water should be used as a fi...

Embodiment 2

[0054] A method for simulating the removal of exogenous strontium in ancient silk fabrics, using the following steps:

[0055] 1) Weigh 100g of madder root from five provinces of Shaanxi, Henan, Anhui, Guizhou and Guangxi, and weigh 50g after drying. After washing the madder roots with deionized water, soak them separately for about 24 hours with deionized water.

[0056] 2) Put the soaked madder roots separately into the stew pot, boil and refine the dyeing solution. Boil each kind of madder root three times, add 900ml of water each time, and pour it out when there is about 300ml left. Mix the three times of refining dye solution, pour out the madder root in the pot, wash the stew pot with deionized water, then pour the mixed dye solution into the stew pot for further refining, and pour it out when 900ml is left. The water used in this process is deionized water. When pouring the dye liquor out of the pot, a piece of silk cloth washed with deionized water should be used as...

Embodiment 3

[0070] A method for simulating the removal of exogenous strontium in ancient silk fabrics, using the following steps:

[0071] 1) Weigh 100g of madder root from five provinces of Shaanxi, Henan, Anhui, Guizhou and Guangxi, and weigh 50g after drying. After washing the madder roots with deionized water, soak them separately for about 24 hours with deionized water.

[0072] 2) Put the soaked madder roots separately into the stew pot, boil and refine the dyeing solution. Boil each kind of madder root three times, add 1100ml of water each time, and pour it out when there is about 500ml left. Mix the dyeing liquids extracted three times, pour out the madder root in the pot, wash the stew pot with deionized water, pour the mixed dyeing liquid into the stew pot for further refining, and pour it out when 1100ml is left. The water used in this process is deionized water. When pouring the dye liquor out of the pot, a piece of silk cloth washed with deionized water should be used as a...

Abstract

The invention relates to archaeology, and discloses a method for simulating removal of exogenous strontium in ancient silk fabric. The method comprises the following steps: 1) extracting and purifying a dyeing solution with madder produced from five provinces with regional representativeness, and dyeing silk cloth samples with the dyeing solution; 2) carrying out processes of thermal ageing and ultraviolet light hydrothermal aging, simulating of marshland burial and the like on the silk cloth samples respectively; 3) processing the silk cloth samples by a water-bath nitrogen blowing apparatus and blowing away particles in the silk cloth samples with high-pressure nitrogen; and 4) cleaning the silk cloth samples with a mixed solution of hydrochloric acid and an aqueous solution of potassium permanganate, and dissolving combined exogenous strontium in the silk cloth samples. The method for simulating the removal of exogenous strontium in the ancient silk fabric, disclosed by the invention, has the advantages of blowing away the particles in the silk cloth samples with high-pressure niteogen firstly, thereby being effective and environment-friendly and low in cost, and effectively removing exogenous strontium in imitated antique silk fabric with low-concentration hydrochloric acid and an aqueous solution of potassium permanganate, without causing damage on the silk cloth samples.

Description

technical field [0001] The invention relates to the field of archaeology, in particular to a method for simulating the removal of exogenous strontium in ancient silk fabrics. Background technique [0002] The traceability of ancient textiles has always been an important research in the field of archaeology. Strontium is a trace element that exists in a variety of living organisms, and often exists in various geological environments such as soil and rocks in a compound state. Strontium has a variety of isotopes. Many scientific studies have found that the ratio of 87Sr / 86Sr in plant and animal fibers in different geographical environments is different. Therefore, the origin of archaeological textiles can be inferred by measuring the ratio of endogenous strontium isotopes. . [0003] However, ancient textiles must have absorbed strontium from the external environment after dyeing, finishing and processing, and then after long-term storage, even geographical transfer, and b...
