内容記述 琉球織物におけるヤマモモの染色性について検討し次の結果を得た。1)ヤマモモ樹皮の熱水抽出物は約36%で, そのうち約31%がミリシトリンで示された。また樹皮の約3%がタンニンであった。熱水抽出物をセロハンで透析して得られる透析部と非透析部において, 非透析部の方に若干染料が多かった。2)素材に絹布および木綿布を用いて染色条件を検討した。その結果, 最適染色条件はいづれの布でも染料濃度が15%, 染色温度が100℃および染色時間は90分であった。3)両布を黄金色に染色するには, 最適染色条件で染色した両布を硫酸銅やカリ明バンで媒染し, その際の媒染剤濃度は50ppmが適当であった。また黒褐色に染色するには, 最適染色条件で染色した両布を鉄塩または泥で媒染し, 媒染剤濃度は鉄塩で50ppm, 泥で10ppmが適当と考えられた。4)染色堅ろう度のうち最も重要な日光堅ろう度および洗濯堅ろう度について検討した。両布を最適染色条件で染色し, 硫酸銅およびカリ明バンで媒染した。その結果日光堅ろう度および洗濯堅ろう度も, 重ね染(染色-媒染をくり返す)の回数と比例し, いづれも重ね染5回以上で安定した。本研究をすすめるために, 終始ご指導ご助言をいただきました九州大学近藤民雄教授に深く感謝いたします。樹種の鑑定をいただきました本学諸見里秀宰教授, 新里孝和助手, またUV測定などにご協力いただいた本学本郷富士弥助教授に感謝いたします。
