This study was carried out to investgate the possiblity of using waste bamboo and bast fiber from paper mulberry for Hwaseonji production. 3 types of Hwaseonji were made in an experimental system, 100% bamboo pulp, bamboo pulp mixed with bast fiber in two different ratios, 70% : 30% and 40% : 60%, respectively. The result were as follows: 1. The chinese ink blots of Hwaseonji made from bamboo pulp only was satisfactory, but its tensile strength showed a low value. In order to improve the tensile strength, we must develope a new beating method with musilige. 2. The burst strength increased as the bast fiber content increased. But it is a special characteristic of Hwaseonji, that an even formation of paper is required. Therefore, only the short bast fiber is needed. 3. The tensile strength was raised by increasing the bast fiber content to 60%, resulting in a more durable Hwaseonji. 4. In even thickness, the higher opacity showed the more bast fiber. So the opacity of product III (bamboo: 40%, bast fiber: 60%) is the highest. 5. The commodity value of hand-made paper should be grade-up after a dedusting process.

Oriental painting paper (Hwaseonji) was prepared from various kinds of plant fibers and its physical properties were investigated. The fibers used were classified into three different length of fibers; long fiber (<1.8 mm), medium fiber (1.4-1.8 mm) and short fiber (>1.4 mm). The fibers were mixed in the ratio of 15% long fiber, 25% medium fiber and 60% short fiber. The Hwaseonji prepared from mixing of the bamboo or rice straw pulp as a short fiber with the long and medium fibers showed excellent physical properties with a high smoothness and uniformity of Chinese ink blot. Mixing with LBKP as a short fiber was resulted in low physical properties, smoothness and wide ink blot. The properties of Hwaseonji, such as ink absorption, roughness and smoothness, may be predicted from the correlation of density with Chinese ink blot and smoothness.

Hwaseonji(Korean traditional paper) used for writing and painting has been made from the mulberry bast-fiber and the short-length fiber pulps, wood pulps. However, besides wood pulps, other short-length fiber pulps also can be used instead of wood pulps. Hence, this research was carried out to make the various Hwaseonjis with the different properties, using the five kinds of short-length fiber pulps respectively. The short-length fiber pulps used in this research were softwood bleached kraft pulp(SwBKP) hardwood bleached kraft pulp(HwBKP), rice-straw bleached sulfite pulp(RsBSP), bamboo bleached kraft pulp(BbBKP) and recycled pulp from vellem paper(RP). And, the mixture ratios of the mulberry bast-fiber pulp and short-length fiber pulps were 100:0, 80:20, 60:40, 40:60 and 20:80. After various Hwaseonjis were made from different mixtures mentioned above with hand-made method, physical properties and chinese ink blot property of each paper were measured. The strengthes were the highest in the Hwaseonji made from the mixture of the mulberry bast-fiber pulp and SwBKP. However, chinese ink blot property and smoothness were better when RsBSP, BbBKP or RP were mixed into the mulberry bast-fiber pulp. As a result, the various kinds of Hwaseonjis which the users can choose based on their needs were made.

This study was carried out to investigate the sheet properties of Indian mallow Hanji, made by different pulping methods, such as alkali and sulfomethylated pulpings, and different stock compositions, various mixing ratios of bast fiber and wood core fibers. Indian mallow Hanjis made with 60% of woody core pulps were shown better Chinese ink spreading distance than those of the others. The Chinese ink spreading distance of the Indian mallow Hanjis made from bast fiber pulp only were unsuitable for Hwaseonji. The Chinese ink spreading distance of Indian mallow Hanji was closely related to the mixing ratio of long fiber and short fiber. Especially sulfomethylated pulping method was superior to alkali pulping method.

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.
