Problems solved by technology

However, the vast majority of leather cultural relics have experienced varying degrees of aging due to being buried in a dry environment for thousands of years, and have almost completely lost the original texture and performance of leather, so they need to be protected.
[0003] At present, there are not many softening methods for leather cultural relics. Generally, lanolin and wax are used directly for fatliquoring. However, due to the poor permeability of lanolin and wax itself, the softening effect is not ideal, and the leather surface is very greasy after adding.

Abstract

The invention relates to a method for softening an aged leather cultural relic. The method specifically comprises the steps of dipping leather in a water bath for a certain duration, softening the leather in another 40-60 DEG C water bath containing a softening agent for a certain duration, absorbing flowing water from the surface of the leather through sponge, pressing the leather on a horizontal platform by a glass sheet and naturally drying the leather in the shade, wherein the softening agent mainly consists of phosphorylated lanolin, castor oil, hydrophilic amino silicon oil, ethanol and tea saponin. The method has good effect, simple and convenient to operate, free of adverse effect on the leather and does not brings greasy feeling to the surface of the leather.

Description

technical field [0001] The invention relates to a method for softening leather, in particular to a method for softening aged leather cultural relics. Background technique [0002] In the splendid history of China, leather was used by the ancients to protect the body from wind and cold, and played an important role in human life. Many preserved leather relics have been unearthed at many archaeological sites. However, the vast majority of leather cultural relics have experienced varying degrees of aging due to being buried in a dry environment for thousands of years, and have almost completely lost the original texture and performance of leather, so they need to be protected. [0003] At present, there are not many softening methods for leather cultural relics. Generally, lanolin and wax are used directly for fatliquoring. However, due to the poor permeability of lanolin and wax itself, the softening effect is not ideal, and the leather surface is very greasy after adding. ....
