전통염색지인 아청지(감지 : 쪽물 염색지)의 재현을 위해 고문헌 감지의 색상을 조사한 후 인도 쪽 분말과 전통니람법에 의해 제조한 염색한지의 염색특성을 검토한 결과는 다음과 같다. 인도산 쪽 분말로 제조한 염액으로 1회 염색한 경우 염색시간이 증가함에 따라 염착량과 색차 모두 증가하였으 며, 특히 염색시간 15분까지는 급격히 증가하였으나 이후 85분까지는 매우 완만하였다. 그러나 2회차에는 염색시간이 5분에서 40분까지는 색차나 염착량 모두 1회때 보다 약간 높거나 거의 같았으나, 40분 이후에는 오히려 감소하였다. 따라서 염색시간은 15분~30분 정도가 적정할 것으로 생각된다. 전통니람을 전통발효에 의해 얻은 쪽물로 반복염색(1회: 15분 염색, 15분 발색)하면서 염색횟수에 따른 색상을 비교한 결과, 1회의 염색에서의 색상은 1.9G로 그레이톤이었으나, 염색횟수가 증가함에 따라 색상도 G→BG→B→PB로 변화하며 색차와 염착량 모두 증가하여 고문서 감지의 색상인 PB는 8회의 염색한지에서 나타났다. 고문서 감지의 색차, 염착량 및 색상과 비슷한 염색횟수는 30번째로 색차 9.82, 염착량 8.56, 색상 6.0PB였다. 그러나 염색횟수는 염액의 인디고 함량에 크게 좌우되며, 인디고 함량이 높으면 염색횟수는 단축 가능할 것으로 생각된다.

The purpose of this study was to produce a prototype after performing the design for the traditional flooring Hanji after coating. It performs the following test results were as follows. The prototype was commissioned to establish optimal coating conditions through. The production of high quality flooring can be produced after the year 192,000 sheets. Largely due to the coating operation to improve hand and contributed to improving the working environment.

Background: To investigate the possibility of using Asarum sieboldii as an environment-friendly fumigant for protecting organic cultural heritages, the inhibitory effect of A. sieboldii extract against wood rot fungi on Hanji was examined. Methods and Results: The physical, optical, and morphological properties of Hanji inoculated with Trametes versicolor and Tyromyces palustris, and exposed to the n-hexane fraction of A. sieboldii extract, were measured. The physical properties were expressed as weight loss, zero-span tensile strength and viscosity and the optical properties were depicted by luminance and chromaticity (L*, a*, and b*). The results showed that, the n-hexane fraction of A. sieboldii extract inhibited the growth of fungi on Hanji, and preserved its condition. At a concentration of 25 ㎎, the n-hexane fraction of A. sieboldii extract maintained zero-span tensile strength, increased viscosity, and restricted discoloration of Hanji. It also was confirmed that the weight of fungi infested Hanji exposed to the extract did not decrease. Scanning electron microscopic images revealed that the spores and hyphae of T. versicolor and T. palustris were not present on Hanji during treatment with > 25 ㎎ of the n-hexane fraction of A. sieboldii extract. Conclusions: These results indicate that the n-hexane fraction of A. sieboldii extract by virtue of its antifungal effectiveness may help in preserving Korean paper cultural heritages, including Hanji.
