A Study on the Development of Hwaseonji from Bamboo Pulp

대나무펄프를 이용(利用)한 화선지(畵宣紙) 개발(開發)에 관(關)한 연구(硏究)

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.
