Paragraph 0106; 0107; 0114; 0115, (2017/12/09)
The invention provides a cation active dye containing an azo structure and a preparing method of the cation active dye. The cation active dye is shown in the description. The preparing method comprises the steps of firstly using a secondary amine compound to react with methoxypoly (ethylene glycol) glycidyl ether to prepare a 2-hydroxy-3-methyl polyether-base substituted propyl tertiary amine compound, then using halo-triazine to connect azo-disperse dye color body containing hydroxyl groups or amino groups, and finally conducting quaternization on tertiary amine in the product to prepare the cation active dye containing the azo structure. The cation active dye has a complete color spectrum, the water solubility is adjustable, the cellulosic fiber is high in substantivity, saltless dyeing can be conducted, the preparing method is simple and the cost is low.
