| Abstract:This study offered a comprehensive review of commonly utilized the types of yellow plant dyes in the process of repairing mounting paper， along with potential challenges encountered during their application. The results showed that yellow plant dyes could be classified into six groups based on pigments’ chemical structure： flavonoids， carotenoids， alkaloids， anthraquinones， tannins， and curcuma. Currently， the primary hidden risks associated with employing plant dyeing solutions for paper restoration included 3 aspects the acidic nature of the dyeing solution， susceptibility to discoloration of dyed paper， high impurity content and complex composition in the dyeing solution. To effectively address these concerns， several approaches were suggested such as adjusting pH values by incorporating alkaline substances into the dyeing solution， adding appropriate amounts of adhesive and fixing agents， and steaming or heating the dyed paper after dyeing treatment. Furthermore， drawing insights from modification research conducted in textile field on cotton and hemp fabrics dyed with plant dyes provided valuable guidance towards exploring feasible strategies for modifying and utilizing yellow plant dyes to enhance safety standards when restored paper cultural relics. |
