Title

The effect of cellulose nanofibers on the function of starch sizing used in historical paper relics

Pages

  17-28

Abstract

 This study aimed to evaluate cellulose nanofibers and study the effects of these material on starch sizing as the most commonly used sizing in historical paper relics and its use as strength enhancer to restore tensile strength and durability. This research was conducted by analytical comparisons method and samples were collected by experiments related to research topics such as pH measurement, calorimetric and the measurement of tensile strength of the samples. In this study, treatment of cellulose nanofibers with weight percentages of 0. 5, 1 and 2%, was prepared as a suspension with water and used to treat the samples containing starch sizing and without it. The results showed that the tensile strength of non-sizing and starch-sizing samples increased after treatment but after aging, the tensile strength of the samples containing starchsizing decreased slightly. The highest tensile strength after treatment was observed for samples containing starch sizing with 2% treatment at 36 Nm/g and after aging, for non-sizing samples with 2% treatment at 28. 2 Nm/g. PH value of nonsizing samples after treatment ranged from 6. 98 to 7. 17 and after aging, it still remained within the neutral range of 6. 85 to 7. 11. pH of samples containing starch sizing after treatment was within the neutral range from 7. 36 to 7. 42 and after aging also remained within the range of 7. 16 to 7. 19. Examination of the color changes of the samples showed that after treatment of non-sizing and starch-sizing samples, the color of the samples is brighter. After the aging, the color of both groups of samples became darker and it tends to yellowing. However, the color changes in the samples containing starch sizing was less than the non-sizing samples.
