Abstract

This study was aimed to investigate the effect of cellulose nano-fibers and ‎chitosan on optical and mechanical properties of chemi-mechanical pulp. For this purpose, some of the bleached CMP pulp of Mazandaran Wood and Paper Industries (MWPI) were randomly selected as a control sample. In addition, the cellulose nanofibers were used as a white gel at 3 levels of ‎0, 2, and 3%. The chitosan was then added to the CMP pulps suspensions at 5 levels of 0, ‎‎0.5, 1, 1.5, 2%, as well. Hand-sheets with a basis weight of 60 gr/m2 were prepared from the mentioned pulps. The optical and mechanical properties were then measured and compared using TAPPI standard test methods. The results showed that by adding chitosan, tear, tensile, burst and breaking length strengths, air resistance, ‎yellowness, and greenness ‎increased and brightness, Cobb 60 and a* factor ‎decreased. On the other hand, with the addition of chitosan and nano-‎cellulose to CMP pulp, the tensile, burst, breaking length strengths, air resistance, Cobb 60, yellowness and a* factor ‎increased and the tear, brightness, and opacity decreased. Moreover, the findings showed that by simultaneous adding 2% chitosan, 2% chitosan, and 3% cellulose nanofibers to the CMP pulp, most of the paper properties were improved. Therefore, ‎it can also be introduced as the best treatment.
