Abstract

The use of cellulose nanofibers as strength-enhancing additive in the wet end section of paper machine increases the general strengths of paper. Nevertheless, considerable increase in draining time from pulp suspension and decrease in paper porosity and opacity has been reported as substantial restriction of its application in this section of papermaking. In this study, the effect of applying cellulose nanofibers in the forming section of paper was examined on the properties of three-ply paper made from recycled fibers. Samples of recycled fibers were prepared from Atrak pulp and paper industries. The refined and not dispersed pulps were, respectively, used to form top layer and other two layers. Standard sheets with 40± 2 g/m2 basis weight were prepared from each of the recycled pulps. Then, cellulose nanofibers were sprayed in 1, 2, 4 and 6 levels (based on oven dry weight of fibers) on one sheet surface and subsequently mild suction was done applying cellulose nanofibers spraying machine designed and fabricated in Zirab research campus. Finally, three-ply paper with 120± 5 g/m2 basis weight were prepared using treated sheets and its properties were evaluated. The overall results revealed that spraying cellulose nanofibers on the forming sheet led to an increase in tensile and burst indices of the paper about 33. 59 and 26. 29 percent, respectively. This process particularly had a considerable effect on the strength improvement between layers in multiply paper which is the most important in these kinds of papers. Thereby, the value of this strength has been significantly increased from roughly 116 J/m2 to 217 J/m2. SEM micrographs prepared from paper thickness confirm larger link between layers and multi-ply condensation.
