Abstract

To evaluate the tensile behavior of Hanji, a preceding paper proposed a theoretical equation of the tensile properties of Hanji including some fiber factors and Hanji thickness. The theoretical values of the tensile strength of Hanji were compared with the experimental tensile strength. In the present work, the random-laid and parallel-laid Hanji sheets were prepared and the tensile behavior of Hanji tape yarn, 8 mm in width, was selected to measure the tensile strength of the fibers related to the fiber stress limit. By calculating all values of the fiber stress limit, curl factor, orientation distribution factor, Poisson's ratio, and two dimensional effects, the general pattern of the predicted breaking stress of Hanji was found to be slightly different from the experimental breaking stress. This difference was attributed to the lower calculated fiber strength than real value, and the difficulty in calculating the theoretical strain of the Hanji fiber at small deformation. Considering these facts, the results were used to assist in the engineering and manufacture of wet-laid nonwovens for specific end-uses.
