The results showed that the dyes with good planarity and linearity were easy to associate, and had low molar extinction coefficient εmax, good substantivity, high exhaust and fixation, high initial dyeing rate, slightly proor migration, levelness and fastne.
结果表明:染料结构的平面性或线性越好,分子间越易缔合,摩尔消光系数εmax越低;染料的直接性越大,其竭染率和固色率高,但初染速度过快,移染性和匀染性乃至牢度稍差;染料线性结构差,其移染性、匀染性和易洗涤性好,但竭染率与固色率较低;用脂肪族软链段作桥基,或在芳香族桥基芳环上引入甲基,能使染料分子的缔合程度下降,改善了以芳香族二胺为桥基染料的上染性能,赋予染料适中的直接性,平缓的上染速度,优异的匀染性及较好竭染率和固色率及各项牢度。
