摘要:	本研究合成了三支分散染料，染料A至染料C的產率均高於85%，將電子基團導入單偶氮染料的對位引起較大的紅移效應因此染料顏色從橙色變為紫色。合成的三支染料於超臨界二氧化碳中對聚酯纖維進行染色，染色布並以耐水洗、耐水、耐汗和耐摩擦牢度等國際標準進行堅牢度評估。研究發現，在超臨界二氧化碳染色中，染料A第一次染色具有超過87％的染料相對上色率染料A適用於聚酯織物的超臨界二氧化碳染色。色牢度評估結果顯示染色樣品的耐水洗、耐水、耐汗和耐摩擦牢度性能都符合商業要求但染色樣品的乾摩擦牢度性能低於商業要求。 In this research we have synthesis three disperse dyes and showed that the yield of Dye A to Dye C was obtained above 85%. Introduction of the withdrawing group to the para-position of monoazo dyes results in a larger bathochromic shifts; as a result of these shifts, the colour is changed from orange to violet. All dyes were dyed on polyester fiber in supercritical carbon dioxide and stand on international organization for standardization for colorfastness to laundering, colorfastness to water, colorfastness to perspiration and rubbing fastness. The study found that in supercritical carbon dioxide dyeing, dye A has more than 87% dye up-take at first time dyeing. It is meaning dye A suitable for dyeing in supercritical carbon dioxide on polyester fabric. The colorfastness result showed that, the laundering, water, perspiration fastness and rubbing fastness properties of the dyed samples were adapted to commercial requirements, but the dry rubbing fastness properties of the dyed samples were lower than the commercial requirements.
