Characteristics of New Hanji (Korean Paper) Produced by Modified Pulping Process
Nam Seok Cho
ABSTRACT
In this study, bast fibers, woody parts and whole woods were pulped separately by alkali, alkali-hydrogen peroxide and sulfomethylated processes and their papermaking characteristics for the special Hanji were evaluated. Also properties of new Hanji products obtained from mixed stocks of various ratios were discussed. Solfomethylated pulps were shown higher brightness and sheet strengths than those from alkali and alkali-peroxide pulps. On the mechanical properties of Hanjis mixed with bast-and woody-parts pulps, and with bast and whole stem pulps, handsheet strengths were decreased with the increasing contents of woody and whole stem pulps. Various Hanjis could make by various mixing of separated cooked Pulps. Especially an excellant Hwaseonji(calligrapy Paper) could be made by one stage cooking of whole stem of paper mulberry by sulfomethylated pulping method.
