-
Paragraph 0031; 0032, (2016/12/12)
The invention relates to a salt-free and alkali-free dyeing type activated dye and a preparation method thereof. The salt-free and alkali-free dyeing type activated dye is a compound having the structure of the general formula (1) (shown in the specification). By virtue of the salt-free and alkali-free dyeing type activated dye, the environmental pollution can be reduced, and the production cost can be lowered; the salt-free and alkali-free dyeing type activated dye is high in product solubility, good in dye fastness, high in dye rate and color fixation, excellent in application performance and convenient to use and is an environment-friendly dye suitable for clean production.

Paragraph 0050; 0052; 0090; 0091, (2016/10/10)
The invention relates to positive ion reactive dye containing polyether amine chain segments and a preparation method of the positive ion reactive dye and belongs to the fields of dye chemical engineering and textile printing and dyeing.The preparation method of the positive ion reactive dye containing the polyether amine chain segments comprises the steps of selecting a compound of an amino-anthraquinone-containing structure as a color body, making the compound react with 1, 3, 5-trichloro-triazine to generate a dichloro-triazine compound, and then making the dichloro-triazine compound react with various types of polyether amine, so that an intermediate body containing monochloro-triazine-based polyether amine is generated; dropwise adding a glycidyl quaternary ammonium salt compound to the intermediate body containing monochloro-triazine-based polyether amine, so that the positive ion reactive dye containing the polyether amine chain segments is generated.The positive ion reactive dye containing the polyether amine chain segments is novel in structure, the preparation condition is mild, raw materials are easy to obtain, little pollution is caused, a product is high in yield and purity, and the dye can be applied to salt-free dyeing of cotton fabric.
