Abstract

In this study, it was explored whether it is possible to improve the fiber orientation of paper by controlling the drainage speed and machine speed during papermaking using a pilot scale wet-web forming machine having open type headbox. After preparing paper specimens by adjusting the vacuum pressure of the web-forming table or the wire speed of wet-web forming machine, the physical properties of each paper specimen, such as grammage, formation, tensile strength (CD, MD), were measured and compared. As the dewatering vacuum pressure of the web-forming table increased, the fiber orientation of the paper decreased. While, the fiber orientation of the paper significantly increased with increasing the wire speed. It was found that it is possible to improve the fiber orientation of the paper caused by high-speed operation by controlling the dewatering conditions.
