Problems solved by technology

Although the active turquoise blue dye has certain water solubility, its solubility is still not high because of its high molecular planarity, and it is easy to associate with molecules to form color stains; especially in the presence of neutral electrolytes, the dye solubility And the diffusion performance will be further reduced, and the dye will be precipitated in the form of multiple molecular associations, resulting in obvious color stains; it shows poor salt and alkali resistance and unstable dyeing

Abstract

The invention discloses a preparation method of a turquoise blue water-soluble dye. The preparation method comprises the following steps of carrying out sulfonation reaction, chlorination reaction and after-treatment on chlorosulfonic acid and copper phthalocyanine which are taken as raw materials to obtain turquoise blue base filter cakes; adding water into the turquoise blue base filter cakes, pulping, adjusting the pH to be 5-5.5, adding phosphorylethanolamine, and reacting until the pH is 2.5-3 to obtain a reaction liquid I; adding a para-ester solution into the reaction liquid I and adding disodium hydrogen phosphate to control the pH to 6-7 to obtain a reaction liquid II after disodium hydrogen phosphate is completely consumed; decreasing the pH of the reaction liquid II to 5.5, adding N,N-dimethylformamide, adjusting the temperature to 25-35 DEG C, maintaining the pH to 5.5-6 with an aqueous solution of M2CO3 and reacting until the pH is changed by 0.1 to obtain a reaction solution III; and finally adding dispersants NNO and MF, standardizing and carrying out after-treatment to obtain the turquoise blue water-soluble dye.

Description

technical field [0001] The invention relates to a water-soluble dye, in particular to a turquoise blue water-soluble dye and a preparation method thereof. Background technique [0002] Reactive turquoise blue is a kind of dye containing copper phthalocyanine structure, and the active group is generally a combination of vinyl sulfone or monochloro-s-triazine and vinyl sulfone. The unique macromolecular structure of reactive turquoise blue leads to its high molecular planarity, so it has a high directness to the adsorption of cellulose, but high directness will cause difficult level dyeing and color flower phenomenon; at the same time, high directness will also cause It brings defects such as unstable shade and poor fastness, and subsequent soaping will further affect the shade and fastness. On the other hand, due to the large molecular group of reactive turquoise blue, the number of water-soluble groups is generally about 3.5, so its solubility is not good, and it is easy to...
