Digital inkjet printing with ultra-fine pigment ink

Digital inkjet printing technology is a new frontier subject for the development of computer inkjet printing technology. The research and development of printing ink is one of the key issues that need to be solved in the promotion and application of this technology. This project mainly focuses on the preparation of ultra-fine pigments, the preparation technology of digital ink-jet printing pigment inks, and the fixing technology of pigments. In order to develop ultra-fine pigment inks suitable for different fiber textile digital ink-jet printing, the pigments have the required fastness and vividness on different fiber textiles, reaching the international advanced level, and being built up to 5000 kilograms of superfine pigment inks. Scale production line. The main technical indicators are as follows: 1. The color fastness of textile digital ink jet printing pattern reaches 3-4 dry rubbing fastness, 2-3 wet rubbing fastness, 3-4 fastness to washing, and light fastness 6- Level 6. 2. The storage and use of digital ink-jet printing general inks have good dispersion stability, do not block the nozzles, and the storage stability is more than 12 months.
