摘要

本實驗係利用自行合成之含羥基偶氮染料及微膠囊包覆分別對聚酯、羊毛及聚酯／羊毛混紡織物進行染色；並探討其染色性。由實驗結果得知；所合成之染料及經微膠囊包覆之染料進行染色經測試；其堅牢度均合乎商業需求。染料官能基中若導入羥基；對染料之溶解度及羊毛之上色性有明顯的提昇。

The resent work aims to investigate and develop series of monoazo dyes containing hydroxy group for the polyester/wool blend fabrics. These dyes were prepared by the coupling of diazotised 2-hydroxyaniline, 3-hydroxyaniline and 4-hydroxyaniline with 2,3-dihYdroxynaphthalene.The resulting hydroxylic-azo dyes were Subjected to LC-Mass and 1HNMR.
]These dyes and their microcapsules were dyed on polyester, wool, polyester/wool blend, the dyeing and fastness properties were evaluated for all cases. Finally the fastness properties of all the dyed samples were in accord with commercial requirements. Introduction of hydroxy groups to the azo dye skeleton enhances the solubility of dye, giving the dyeability of wool increase. All of them were found to dye polyester and wool fabrics to approximately the same deapth.
