Abstract
Paper documents are included an important part of cultural and historic property. As time passes, these works are always prone to yellowing as an aesthetic damage. In this study, for the purpose of reduce the colour changes of Klucel-G polymer (Hydroxypropyl cellulose) as a very common size in paper documents restoration, inhibition behavior of colour change for two types of Nanofibers of Bacterial Cellulose (BCN) and Fibrillated Cellulose (NFC) into this polymer, by coating onto filter-paper samples were evaluated; Then, using artificial aging, UV-Vis spectroscopy and SEM microscope methods, the results were analyzed. Based on findings, the presence of these nanofibers after aging led to inhibition of the total colour changes (ΔE), so that BCN showed the highest inhibition. As a sub-purpose, increasing the concentration of Klucel-G led to exacerbation of colour changes after aging. Totally, adding these nanofibers into the Klucel-G, as a coating on paper prevent colour changes and on the other hand, applying more concentrations of Klucel should be avoided.
