摘要

本研究中自行合成一系列3-（N,N-二乙基）氨基乙醯苯胺衍生單偶氮紫色分散性染料，並使用這些染料在超臨界二氧化碳中對聚酯進行染色，且討論在鄰位添加鹵素原子對染色強度和染色堅牢度的影響。結果顯示染料V3的K/S值20.02，相對上色率78.11%，染料V4的K/S值20.563，相對上色率86.43%，染料V5的K/S值17.532，相對上色率81.42%。由此可知自行合成的染料中以染料V4和染料V5較適合用於超臨界二氧化碳染聚酯織物；由染色堅牢度結果顯示：染料V3、染料V4與染料V5其堅牢度均符合商用染料3-4級要求。

In this study, a series of 3-(N, N-diethyl) aminoacetanilide-derived monoazo disperse dyes were synthesized and used to dye polyester in supercritical carbon dioxide and discuss the effect of adding halogen atoms in the ortho position on the dyeing intensity and dyeing fastness was investigated. The study found that the K/S value of the dye V3 is 20.02, the relative dye uptake is 78.11%, and the K/ S value of the dye V4 is 20.563, the relative dye uptake is 86.43%, and the K/S value of the dye V5 is 17.532, the relative dye uptake is 81.42%. It can be seen that dye V4 and dye V5 are suitable for supercritical carbon dioxide dyeing of polyester fabrics. The dyeing fastness results show that the, dye V3, dye V4and dye V5 all meet the commercial dyeing fastness requirements of grades 3-4.
