本實驗主要目的乃針對聚酯/羊毛之混紡織物製備出一系列含有磺酸基團之單偶氮染料。所欲製備之染料可藉由2-胺基苯磺酸，4-硝基苯胺，2-羥基苯胺，3-羥基苯胺和4-羥基苯胺等五種重氮成份，經重氮後製成重氮液再分別與3-(N,N-二羥基乙基)胺基氯苯，3-(N,N-二乙基)胺基乙醯苯胺，4-(3'-羥基-4'-甲基)?咯苯磺酸，N-氰乙基-N-乙基苯胺等不同的偶合成份經偶合反應後獲得。自製之含磺酸基偶氮染料再分別對聚酯、羊毛及聚酯/羊毛混紡織物來進行染色，並對其染色堅牢度進行評估。
The present work aims to investigate and develop a series of monoazo dyes containing sulfonic group for the polyester/wool blends fabrics. These dyes were obtained by the coupling of diazotised 2-aminobenzenesulfonic acid, 4-nitroaniline, 2-hydroxyaniline, 3-hydroxyaniline and 4-hydroxyaniline acid with3-(N, N - dihydroxyethyl) aminochlorobenzene, 3-(N, N-diethyl)-aminoacetanilide, 4-(3-hydroxy- 4 - methylpyrrolyl)benzene sulfonic acid, N-cyanoethyl - N -ehylaniline. These dyes were dyed on polyester, wool, polyester/wool blend fabric and their dyeing and fastness properties evaluated. The fastness properties of all the dyeing samples were in accord with commercial requirements.
