초 록

부여 궁남지 출토 짚신 시료를 동정하였고 짚신의 보존처리를 위하여 수침고목재 보존처리에 널리 사용되고 있는 PEG와 Acrylic 수지 중 토층경화제로 주로 사용되고 있는 Primal MC-76, 진공동결건조 등의 방법을 적용하여 중량변화율을 알아보았고, 이에 대한 흡습성 실험을 실시하였다. 그 결과 연구대상 초본류 시료는 부들류 (Typha spp)로 동정되었고, 중량변화율에 있어서는 PEG 2-Step 처리 후 진공동결건조를 한 경우가 가장 안정적인 변화를 나타내었으며 색변화에 있어서도 가장 변화가 적은 것으로 확인되었다.

ABSTRACT

To preserve straw sandals excavated at Goongnamji site, this study examined the weight change rate by applying the methods of Primal MC-76 and vacuum freeze-drying used mostly as a earth-layer hardening material among PEG and acrylic resin, which are applied widely for preservation of waterlogged archaeological wood, as a means to preserve plant-based cultural properties along with the examination of the subject material. An experiment was also performed on moisture absorption after treatment. The materials of sandals were identified as Typha spp. The weight change experiment revealed that the vacuum freeze-drying after being treated with PEG 2-Step showed the most stabilized changes in weight, while it offered the smallest change in color as well.
