The purpose of this innovation is to evaluate the nanoparticles of Katira (Tragacanth gum), to optimize for reinforcing agent to restore mechanical strength and stability of historical paper documents. The method and approach of the research is practical study and it is an analytic-comparative method involving gathering information through the relevant tests to the research topic, such as pH tests, mechanical strength, SEM analysis, zeta potential analysis to check the depth of penetration and high stability. Katira nanoparticles with different weight percentages were extracted and calcium hydroxide was added for increasing its pH and glycerol was added for increasing flexibility. The treatment was sprayed on the paper samples and then it was done for humidity-temperature aging according to ISIRI-4706 standard number for 12 days and light aging according to ASTM D-3e02-6819 standard number for 6 days. The results obtained from the pH analysis, the pH of the treated samples before and after aging increased compared to the blank sample about 40%. SEM analysis showed the physical synthesis of the broken fibers. Mechanical strength Analysis in the newspaper samples, before and after aging, showed an increase in strength of 3 to 15% depending on the amount of gum that was used. The result of colorimetric analysis showed no change in the color and opacity of the reinforcing material. In the zeta potential analysis, the size of the material was found to be 4.5 to 5 nm, which shows high penetration depth and stability in its resistance.
