Abstract

In this study, the characteristics of various raw hairs used for traditional Korean brushes were examined; further, the characteristics and deterioration patterns of Korean, Chinese, and Japanese brushes were compared, with a quantitative evaluation to assess the brush performance. The tensile strength was generally found to be higher with a greater fiber thickness. Among the hairs examined, the back and flank hair of goat was more damaged than that in other parts, and the tensile strength was low. Higher elasticity of the brush made with hair of high cysteine content was measured. Owing to deterioration by use of the brushes, artificial drying brushes had a higher yellowness index and lower tensile strength than natural drying brushes. Further, it was confirmed that brushes with good absorbency exhibited good consistency, but not good elasticity. Thus, the performance of the brush can be influenced by the kind of material used and the brush usage pattern. In addition, it is possible to identify the material science characteristics of brushes which have been produced only by experience; therefore, the results of this study could provide basic data for manufacturing brushes employed in conservation treatment, in the future.

본 연구에서는 한국 전통 붓에 사용되었던 다양한 원모의 특성을 확인하고 실제 사용에 따른 한국, 중국, 일본 붓의 특성과 열화 양상을 비교하였으며, 붓 성능을 비교하기 위한 정량적 평가를 실시하였다. 다양한 원모별 특성 비교 결과, 털의 굵기가 굵을수록 대체로 인장강도가 높게 나타났다. 그 중 염소의 등과 옆구리 부분의 털은 다른 부분보다 손상이 많이 관찰되었고, 인장강도도 낮게 나타났다. 또한 시스테인의 함량이 많은 털로 제작한 붓은 탄력도 강하게 측정되었다. 붓의 실제 사용에 따른 열화 실험 결과, 인공건조한 붓은 자연건조한 붓보다 황색도 지수가 더 높고, 인장강도는 더 낮게 나타났다. 또한 흡수력이 좋은 붓은 지속력도 좋으나 탄력은 좋지 않은 것으로 확인되었다. 본 연구를 통해 어떤 재료로 붓을 만들고, 붓을 어떻게 사용하고 관리하는지에 따라 붓의 성능에 영향을 미칠 수 있음을 확인할 수 있었다. 또한 필장들이 그동안 경험과 감각으로만 제작해 왔던 붓의 재료과학적 특성에 대해 규명할 수 있었으며, 향후 보존처리용 붓 제작을 위한 기초자료로 활용 가능할 것으로 기대된다.
