Abstract:	本實驗主要目的乃針對聚酯織物與尼龍織物製備出一系列含有苯並吡喃粡基團之螢光染料。所欲製備之染料可藉由苯二胺、醋酸氰乙酯、派啶等成份經縮合反應後製成2-苯並咪唑基乙酸乙酯，再分別與水楊醛、2，4-二羥基苯甲醛，4-N , N-二乙基胺水楊醛等不同的中間體再行縮合反應後獲得黃色螢光染料，再與兩二腈進行縮合反應後獲得紅色螢光染料。自行合成之螢光染料與分散性紅色277號染料再對聚酯織物與尼龍織物染色並且評估染色堅牢度。 The present work aims to investigate and develop a series of coumarin dyes containing benzimidazole group for the polyester fabrics , lese dyes were obtained by the condensing 2-benzimidazolyl acetic acid with salicylaldehyde, 4-N,N-diethylaminosalicylaldehyde or condensing ethyl 2-benzimidazolyl acetic acid with 2,4-dihydroxybenzaldehyde in the present of piperidine. These dyes were dyed on polyester and nylon, and their dyeing and fastness properties evaluated. The fastness properties of all the dyed samples were in accord with commercial requirements except dry heating of dye F which was dyed in 1.5% O.w. f.
