摘要

本實驗乃利用一系列自行合成之雙羧基偶氮染料，分別對聚酯、羊毛及聚酯/羊毛混紡織物來進行染色。染料製備以2-氨基基苯甲酸、3-氨基苯甲酸和4-氨基苯甲酸，再分別與兩種不同成分之偶合物劑3-羥基萘甲酸、水楊酸經偶合反應後獲得。經純化後之染料再以質譜、氫-核磁共振光譜、紅外線光譜與元素析等測定其構，並評估各種染色堅牢度。由結果得知含3-羥基萘甲酸染料其堅牢度性質均合乎商業需求，染料官能基中若導入2個羧酸基團對染料之溶解度有顯著的提升，對羊毛之染著量亦有提升。

The present work aims to investigate and develop a series of diearboxylic-azo dyes for polyester/wool blend fabrics. These dyes were obtained by the coupling of diazotised 2-aminobenzoic acid ,3- aminobenwic acid and 4- aminobenzoic acid with 3 – hydroxy naphthoic acid, salicylic acid. The resulting carboxylic-azo dyes were subjected to LC-Mass, IH-NMR. All of dicarboxylic-azo dyed were dyed on polyester, wool polyester/wool blends fabrics, and fastness properties evaluated. The fastness properties of all the dyeing samples were in accord with commercial requirements,Introduction of two carboxy groups to the azo dye skeleton enhances the solubility of dye, giving the dye ability of wool increase. Three of them was found to dye polyester and wool fibers to approximately the same depth.
