Abstract
In recent years, it had focused on the improvement of paper properties by addition of NFC (Nano-fibrillated Cellulose). Although the addition of NFC to wet-end of papermaking process could be suggested as a new solution to improve the strength properties of paper, it was not possible to avoid the bad drainage caused by the added NFC's chocking pores of wet web. Instead of the direct addition to wet-end, spraying of NFC to web in wire-section was tried in this study and evaluated by checking various paper properties including surface smoothness, tensile strength, folding endurance and stiffness. According to the increase of spraying amount of NFC, above mentioned paper properties were enhanced without excessive deterioration of drainage. Compared with direct introduction to wet-end, spraying could be regarded as a more proper method to enhance the surface smoothness and strength properties of paper.
