영문 초록

Damyang Province is famous asfor the native habitat of bamboo which has been used as the raw materials for various artistic craft and hygienic tools, e.g., small fork and tooth brush. This study was carried out to analyze the bleaching characteristics of bamboos grown in Damyang region and to check out the chemical components residues in bleach-treated bamboo specimen. Typical three bamboo species, i.e., Maengjongjuk(P. pubescens), Somdae(P. nigra var. henonsis), Wangdae(P. bambusoides) revealed almost similar response to bleaching agents(hydrogen peroxide, sodium chlorite, and sodium hypochlorite) showing different degree of bleaching and time-dependency after treatment. 35% hydrogen peroxide solution showed excellent performance in initial bleaching and sustained effect in whiteness, redness, and yellowness regardless of bamboo species, however, sodium hypochlorite solution showed poor and unstable bleaching effect of all three bamboo species. Bleached bamboo specimens retained various chemical components which were quantified in anion chromatograhy analysis. Chloride(Cl-), the most hazardous element among them was detected at significant level in the bamboo specimens. Its retention drastically varied among bleaches, 925.6 ppm to 1123.6 ppm with sodium hyperchlorite, 463.8 ppm to 529.2 ppm with sodium chlorite, and 219.9 ppm to 301.7 ppm with hydrogen peroxide, respectively. The author concluded that bleaching treatment could be selected according to the designers’ intention for the coloring of final product and hydrogen peroxide is the best bleaching agent at present, but sodium hypochlorite should not be used in the bleaching regardless of bamboo species experimentally and commercially.
