Abstract

In this study, the effect of cellulose nanofibers on the properties of handmade papers produced from hemp and wood pulp fibers was assessed. Also, the nanofiber application as a strength enhancer for restoration of handmade papers was investigated. Firstly, handmade paper samples were prepared. Cellulose nanofibers with weight percentages of 0.5, 1 and 2% were prepared as a suspension in water the samples were treated by the suspensions. Blank and treated samples were tolerated accelerated aging process and then pH, colorimetric and tensile strength tests were performed. Comparison of blank and treated samples results showed that the tensile strength of the both groups of hemp (H) and wood pulp (WP) papers were increased after treatment by cellulose nanofibers. Aging process caused to reduction in tensile strength of treated samples but it was increased in comparison with blank samples before and after aging. The pH of the papers in both groups was in the alkaline range after the treatment and aging. Brightness of papers was increased after the treatment and color changes in the samples were due to their accelerated aging conditions.
