삼 인피섬유 혼합율이 종이의 보존 특성에 미치는 영향

초록

Despite the ubiquity of electronic media, paper is still the most generally readable carrier of information. Because paper materials are deteriorated by chemical, biological and physical factors over time, therehave been major concerns about the decay of large collections of books, publications, old maps, historicalartifacts, and written records. Therefore, manufacture of permanent paper has been a highly debated issuein paper conservation research. Through the use of permanent paper, our new records, journals, librarybooks, art works, and all culturally and historically important documents can be preserved. In this study,handsheets were made of mixture of hemp bast fiber produced by soda pulping and HwBKP varying theamount of hemp. Physical, mechanical and optical properties of each handsheet were examined. As theratio of hemp bast fiber increased, mechanical properties were improved significantly, but opacitydecreased. After aging, the optical properties of the handsheets mixed with the hemp bast fiber more decreasedthan those of the non-mixed handsheet. The more mixture ratio of hemp bast fiber increased, themore decreasing rate of optical properties increased. As a result, it was confirmed that hemp bast fiberis a very promising resource for the manufacturing of permanent paper.
