The invention discloses high-temperature direct-injection disperse ink as well as a preparation method and an application thereof. The ink is prepared from the following raw materials in parts by weight: 15-60 parts of high-temperature
disperse dye, 0.3-20 parts of dispersant, 30-60 parts of
organic solvent, 10-50 parts of water, 0.5-10 parts of surfactant, 0.05-0.2 part of
preservative and 0.05-0.2 part of
defoamer. The preparation method comprises the steps of evenly mixing the high-temperature
disperse dye, the dispersant, the
organic solvent and water together, adding
zirconium beads for
grinding and dispersing, and then adding the rest
organic solvent, water, the surfactant, the
preservative and the
defoamer to the mixture, mixing evenly, and filtering to obtain the filtrate. The ink is applied to a novel industrial
digital textile printing machine and in particular to a
textile printing
machine with a precision work 508GS
nozzle; the ink can be directly injected for printing by using the printing
machine, and therefore, the
utilization rate of the ink is increased, the cost is reduced and the environmental
pollution is reduced; the ink can be dyed quickly at high temperature without
transfer printing, and thus has the advantages of short
dyeing time, firm
dyeing and the like.
