摘　　要：介绍了靛蓝在染液中存在的4种形态以及靛蓝浸染4种合成纤维,即涤纶、锦纶、氨纶和腈纶的研究进展.靛蓝以单分子状态渗透进入4种合成纤维内部,其中非离子态的隐色酸对4种合成纤维的亲和力最大.控制染浴pH值是控制靛蓝形态分布的关键,当pH值为6～7时,靛蓝浸染染色后的4种合成纤维都具有较好的得色量,且得色强度排列顺序是：氨纶、腈纶、锦纶、涤纶.Four forms of indigo existed in the dye bath are introduced and progress on the exhaust dyeing of four synthetic fibers, that is PET, PA, PU and PAN, with indigo is discussed. Indigo dye existed as single molecules penetrates into the four synthetic fibers matrix. The non - ionic form has the highest substantivity for the four synthetic fibers. The dye bath pH value is the most critical to decide the fraction of each of the indigo species. When the dye bath pH is 6 - 7, the color yield of indigo through an exhaust dyeing procedure on four synthetic fibers is greater and the sequence of the color strength is followed as PU, PAN, PA and PET.
