영문 초록

The eco-material, bamboo is famous for its sustainable growth and high carbon reserving capacity which has been used for various crafts and hygienic tools. This study was carried out to analyze the safe coloration and lasting possibility of three domestic bamboo species, i.e. Wangdae (P. bambusoides), Maengjonjuk (P. pubescens), Somdae (P. nigra var. henonsis). Intrinsic color characteristics of dried culm of Wangdae is the most light (highest L-value) and Somdae showed the highest b-value (high chroma, yellowness). Three bamboos revealed common response to heat treatment showing more distinct L-value change than those of a-value and b-value comparatively. So the lightness was chosen as the index of heat reaction in this study. The decrease of L-value of Wangdae due to heat was noticeable from 140°C and showed drastic darkening at 200°C for 30min. Maenjonjuk reacted slowly showing the darkening in 30min treatment, while Somdae showed quick response in short treatment (15 min) at each temperature. Therefore the author concluded that Wangdae and Somdae were suitable for short heat treatment in bamboo coloration and high temperature (200°C) was recommendable for high level darkening regardless bamboo species. Light fastness of heat treated bamboo culm were strengthened with increase the temperature and duration of heat treatment with three bamboos commomly. Consequently, author got the important information on the coloration and fastness for the utilization of domestic bamboo species.
