Anatomical, Morphological, and Chemical Characteristics of Paper‐mulberry Wood and Bast Fiber for Raw Material of Korean Paper(Hanji)

Abstract

This study using a method different from those employed previously, the anatomical characteristics of paper-mulberry wood were confirmed by observing three different sections. In addition, the factors affecting the pulp and papermaking processes were analyzed in terms of morphological properties such as the fiber length and width, lumen width, and chemical composition of the paper-mulberry bast fiber. The anatomical characteristics of the paper-mulberry wood were a ring porous or semi-ring porous structure with the vessels showing solitary pore and radial array. The medullary ray of the tangential section showed 1-3 rows and common helical thickening. Consequently, the paper-mulberry wood has the same anatomical characteristics throughout. The morphological characteristics of the paper-mulberry bast fiber are a fiber length of 6.58 to 9.01 mm, fiber width of 15.85 to 27.80 μm, lumen width of 4.50 to 12.54 μm. The D sample of Gangwon was the most suitable for the pulp and papermaking processes, in terms of its derived morphological ratios. Comparing the chemical compositions, the C sample of Gyeongsang had a high holocellulose content (90%). Thus, the findings herein will aid in determining the quality of Korean paper post production.
