    摘要: 在超臨界二氧化碳的染色技術中,欲達到深色染需借助反覆升降壓的操作,而這樣的作法也較耗費能源,因此本研究即為尋找在超臨界二氧化碳染色系統中,可以對細丹尼聚酯織物助染之溶劑,結果顯示,傳統聚酯纖維所用的溶劑在本系統中並沒有明顯的助染效果,而與染料有良好溶解性的溶劑(例如二甲基甲醯胺和二甲基亞堸)則可以提高樣本的染著量近一倍,而且這種染色方法對纖維的結晶性質及熱性質也沒有明顯的影響,織物染色後也不須水洗及烘乾的後處理。因此在染機有完善回收設備下,對被染物壓吸少量溶劑將是一種經濟的染色方法。

    Continuous compressing and decompressing processes are necessary to get deep shade in supercritical fluids dyeing. In this experiment, we tried to find cosolvent in fine denier polyester fabric dyeing with carbon dioxide as a solvent in order to raise the exhaustion of dye. From the results, we can see solvents like carrier which can swell the fibers have no sufficient effect in the increment of dyeability. But another solvents such as DMF (dimethylformamide) and DMSO (dimethyl sulfoxide) which can disperse the dye particles can raise the dye exhaustion to twice about the normal procedure (dyed only with carbon dioxide), and cannot effect the properties of crystallize and heat of these fiber. After treatments are still needn’t in this technology and materials used in this process can be recycled. So dyeing polyester by supercritical carbon dioxide technology with little cosolvents is more economic than water dyeing method.
