本研究中，我們自行合成了四支分散性染料，染料ⅠA至染料ⅣA的產率均高於85%。研究發現將長鏈烷基導入單偶氮染料的胺基中引起較大的紅移效應，因此染料顏色從陳玫紅變為暗岩藍。自行合成的四支染料分別於超臨界二氧化碳中對聚酯纖維進行染色，染色布樣並以耐水洗、耐水、耐汗(酸、鹼)和耐摩擦色牢度等ISO 和 AATCC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ⅡA和ⅢA第一次染色具有超過85％的染色相對上色率。這意味著染料ⅡA和ⅢA適用於聚酯織物的超臨界二氧化碳染色。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。
In this research we have synthesis four disperse dyes and the yield of dye IA ~ dye IVA was obtained above 85%. It was found that the long chain alkyl group was introduced into the amino group of the monoazo dye to cause a large redshift effect, so the dye color changed from old rose to dark slate blue. All dyes were dyed on polyester fiber in supercritical carbon dioxide and the dyed sample were evaluated for ISO and AATCC standards such as washing color fastness, water color fastness, perspiration (acid, alkali) color fastness and rubbing color fastness. The study found that in supercritical carbon dioxide dyeing, dye IIA and IIIA has more than 85% dye relative up-take at first time dyeing. It is meaning dye IIA and IIIA 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.
