硬化皮质文物的保护研究

A Study on the Leathern Cultural Relics Softening

皮质文物由于长时间经受不良环境的影响,出现糟朽、变干、变硬、脆化等病害,由于皮质文物不同于普通皮革,普通的修复方法难以对其起到效果。本研究通过清洗、软化、补水、加脂处理,改善了皮质文物的的空间结构及其组成,提高了皮质文物的含水量、含脂量,保护处理后的皮质文物在柔软度、弹性、厚度等机械性能方面都有明显的改善。该研究对皮质文物的保护具有一定借鉴作用。

The leathern cultural relics have been buried under the ground for a long time, so theirappearance and mechanical property have been damaged seriously. Because leathern cultural relics are different from the ordinary leather products, the restore method have no effect on them. The glycerine has a good function of remaining water, and its fat can replace the lost fat organic matters in the leathern cultural relics. This study shows that its water content and fat content have the distinct enhancement through a series of processing steps such as enzyme preparation cleaning, softening, water adding, dewatering, adding fat and fat-liquoring agent. After three months, soft effect is better than untreated leathern cultural relics. The experiment indicates this method can soften the leathern cultural relics to a certain extent and lay the foundation for the restoration of the leather cultural relics.
