Abstract
Museums around the world are filled with large number of cellulosic materials, like textiles that have suffered from the scourge of the consequences of being exposed to the destructive processes of its fibres, dyes, inks, mordants, etc., due to the exposure to the action of transition metals; in a famous mechanism worthy of study, this means valuable sources are lost from time to time. For this, the foregoing motivated this chapter to move toward finding and identifying the causes of these destructive mechanisms of the cellulosic fibres. Not only this, but also to try to find ways that would measure the degree of what results from exposure to destructive interactions, especially the weakness of mechanical properties, free radicals content, depolymerization, and the demise in some cases; as well as the fading and darkening of dyes and inks, or disappearance completely in many cases. Besides the darkening of cellulosic substrates, this chapter will deal with experimental studies, as well as citations and reference studies.
