Abstract

The invention discloses a softening method aiming at hardened fur cultural relics. The softening method comprises the following steps: A) taking and completely soaking cultural relic samples for 24 hours; B) soaking the samples treated in the step A) in a water bath containing 50wt% ethanol water solution to be treated for one hour; C) soaking the samples obtained in the step B) in a water bath containing a softening agent to be softened for 0.5-2 hours; D) completely soaking the samples treated in the step C) in the water bath containing 50wt% ethanol water solution again to be treated for one hour; E) after taking out the samples treated in the step D), taking a solution of glycerin and ethanol in a mass ratio of 1 to 4, directly smearing the solution of glycerin and ethanol on the surfaces of the samples and removing redundant glycerin with alcohol wipes after standing for 10 minutes; and F) opening and airing the obtained samples. The softening method has the beneficial effects that effects are obvious; the elasticity and other mechanical properties of fur are improved when the softening method is applied to hardened fur; the method is simple, is simple and convenient to operate and can not cause secondary damages to fur cultural relics.

Description

technical field

[0001] The invention belongs to the field of cultural relics protection, in particular to a method for softening aged fur cultural relics. Background technique

[0002] In China's long history, the Chinese people have long used animal fur to make clothes to keep out the cold. In recent years, with continuous archaeological excavations, a large number of exquisite fur cultural relics have been unearthed. However, due to long-term buried underground, a large number of fur cultural relics have hardened and cracked, and the appearance and performance of fur cultural relics are seriously affected, which is not conducive to the long-term preservation of cultural relics.

[0003] At present, there are many softening methods for leather cultural relics. Generally, lanolin and wax are used. However, due to the long time of fur cultural relics, the internal protein fibers are seriously deformed, resulting in very tight spacing between fibers and narrow fiber spaces. ...

Examples

Embodiment 1

[0013] Embodiment 1 adopts the following steps:

[0014] A) take the sample of hardened fur cultural relics, put it into deionized water and fully immerse it for 24 hours;

[0015] B) Immerse the treated sample in step A) in a water bath containing 50% ethanol aqueous solution for treatment, the temperature of the water bath is 20 degrees, and the time is 1 hour;

[0016] C) Soak the sample obtained in step B) in a water bath containing a softening agent, the temperature of the water bath is 20-30 degrees, and soften for 0.5h; the content of each component of the softening agent is calculated by mass fraction: urea 1%, sodium chloride 4 %, polyethylene glycol 5%, ethanol 45%, deionized water 45%;

[0017] D) The sample treated in step C) is completely immersed in a water bath containing a mass fraction of 50% ethanol aqueous solution again for treatment, the temperature of the water bath is 20 degrees, and the time is 1h;

[0018] E) After taking out the sample treated in st...
