Abstract
The objective of this study was to evaluate the possibility for the coffee filter paper of Hanji. In this study, the samples for Hanji filter papers were prepared with three different mulberry fiber contents of 10, 30 and 50%(w/w). Surface brightness and apparent density of hand-made Hanji decreased with increasing mulberry fiber contents. However, values of thickness, tensile strength, wet tensile strength, burst strength, and folding endurance for hand-made Hanji increased by increasing the contents of mulberry fibers due to fiber-to-fiber bonding. The results of the coffee extraction test using the developed filter papers showed no significant differences between commercial filter paper and Hanji filter paper. Therefore, Hanji filter paper containing more than 30%(w/w) mulberry fiber may have potential uses for the dripped coffee filter application from a physical property point of view.
