In reactive dyeing, the Turquoise Blue, Blue, Brilliant Green and other sensitive colors easily dyed flowers. To solve this problem we have done a lot of analysis tests, the use of solubilizer to increase the solubility of dye; dyeing process using soft water, and add the chelating agent to reduce the sodium sulphate caused by hardness, while improving, but you can not completely avoid the dyeing flowers and subsequently by a large number of trials found that there is a dye bath Fe3 +, Cu2 +, Zn2 +-induced dye accumulation of heavy metal ions such as lead-color flowers. Chelating agents on the market today chelation of iron ions are temporary in nature, with time, temperature, gradually release the Fe3 +, Cu2 +, Zn2 + and other heavy metal ions, while the dye molecular structure of a large anthraquinone dyes easily In the Fe3 +, Cu2 +, Zn2 + and other heavy metal ion-induced aggregation occurs, leading to color flowers. Domestic Sodium Sulfate, dyes containing Fe3 +, Cu2 +, Zn2 + and other heavy metal ions, plant piping, valves, boilers, piping contains large amounts of Fe3 +, Cu2 +, Zn2 +, etc. Therefore, the presence of iron is difficult to avoid, and no certain rule by adding metal ions, after blocking agents can block free of Fe3 +, Cu2 +, Zn2 +, in order to avoid color flowers.
在活性染料染色中，翠蓝、宝蓝、艳绿等敏感颜色极易染花。为解决此问题我们做了大量分析试验，使用增溶剂，增加染料的溶解度；染色过程中使用软水，并添加螯合剂来降低元明粉引起的硬度，虽有所改善，但不能彻底避免染花，后经大量的试验发现是染浴中存在Fe3+，Cu2+，Zn2+等重金属离子诱发染料聚集引起色花。目前市场上的螯合剂对铁离子的螯合均为暂时性，随时间延长，温度的升高而逐步释放出Fe3+，Cu2+，Zn2+等重金属离子，而染料分子结构大的蒽醌类染料极易在Fe3+，Cu2+，Zn2+等重金属离子的诱导下发生聚集，从而导致色花。国产元明粉，染料中含有Fe3+，Cu2+，Zn2+等重金属离子，工厂管道、阀门、锅炉管道中含有大量Fe3+，Cu2+，Zn2+等，所以铁离子的存在是很难避免的，且无一定规律，加入金属离子封锁剂后可以封锁游离的Fe3+，Cu2+，Zn2+，从而避免色花。
