Research for the conservation of cultural heritage in the context of the circular economy

Abstract

The heritage woven objects could be analyzed for defects hidden to the naked eye using non-invasive and non-destructive ultrasonography techniques. Ultrasonography is able to offer information about altered areas, such as gasps, interruptions, discontinuances, narrowed areas, fiber breaks, different densities of the material, defects caused by natural or anthropic factors: improper storage and exposure conditions, the presence of microorganisms and traces of their activity, mechanical causes etc. By recycling of the cotton fibers from other decrepit materials, which are not directly usable, the recondition and rendition of the national and world cultural heritage of these refurbished objects would be accomplished. The impact on the environment is diminished compared to the case when new cotton fibers are created.
