The aim of this study is the evaluation of nanoparticles of Persian Gum for reinforcement of historical cellulose textiles to prevent the erosion process. The method of study is based on the extraction of nanoparticles of Persian gum, optimization and spray of substance on the textile samples. One sample of each mass fraction is placed under accelerated aging of humidity - temperature and light for comparison. Zeta potential is computed to study the stability of the treatment, and pH measurement is exploited to evaluate the pH of the proposed approach and the reinforced samples. To evaluate the resistance of the reinforced samples, the samples are studied under SEM test and mechanical resistance analysis. The result of Zeta Potential reports high stability of nanoparticles equal to -25.3 mV. Moreover, the performed experiments show that preserves its steady and uniformity even after time passes. pH Measurement is applied to report the pH of the reinforced samples in alkaline range before and after aging. pH has improved from the range [0.84, 0.92] before aging to the range of [0.95, 1.15] after aging. SEM reported strengthening and repairing the broken fibers. Mechanical resistance analysis showed that the power of failure has been increased, and presented the tensile stress before and after aging.
