위조문서 감별을 위한 현대 문서용지 특성 분석 ( II ) = 섬유원료 분석

다국어 초록 (Multilingual Abstract)

In order to investigate the characteristics of modern paper, the fiber type and blending ratio of the domestic paper document samples for which the year of publication has been confirmed were examined. In the results, major fibers including softwood bleached kraft pulp (SwBKP), hardwood bleached kraft pulp (HwBKP) and bleached mechanical pulp (MP) were found to be used in modern paper. SwBKP has been steadily used up to 23% of the total fiber in modern paper to improve paper strength. Prior to 1980, MP was used as the main fiber furnish of the document paper.
However, since 1980, it has changed from MP to HwBKP. This change is presumably due to the high lignin content of the mechanical pulp that causes fast color reversion. It also appears to be affected by increasing consumer demand for high quality such as high brightness and excellent printing property. However, some samples produced after 1980 still contain small amounts of MP fibers. Since most of the pulp used in Korean paper mills is imported pulp, a small amount of MP is sometimes used to reduce production costs. To increase the reliability of this study, we need to increase and to update data base continuously.
