A kind of preparation method of low-salt reactive dye and its application in ink for inkjet printing |
| abstract |
The invention provides a preparation method of a low-salt reactive dye, which specifically comprises the following steps: firstly adopting cellulose nanocrystals to modify a polyamide matrix membrane to obtain a matrix membrane modified by cellulose nanocrystals; adopting in-situ synthesis The sodium alginate/polyacrylamide composite gel was prepared by dipping method, and then the modified sodium alginate gel layer was prepared on the surface of the matrix membrane by dipping method; And add glutaraldehyde solution for cross-linking modification, the prepared mixture is sprayed on the surface of modified sodium alginate gel layer to obtain chitosan cross-linked modified carbon nanotube active layer; The nanoparticle coating forms a nanofiltration membrane, and the reactive dye is dissolved in water to obtain a dye solution, which is subjected to microfiltration and nanofiltration treatment in turn to obtain a low-salt reactive dye. The reactive dye prepared by the method can be used in the preparation of inkjet printing ink, and the prepared ink has good stability and is not easy to cause pollution to the nozzle. |
