Abstract

The invention discloses a disperse dye ink used for thermal transfer printing of thin paper and a preparation method thereof. The components of the disperse dye ink used for thermal transfer printing of thin paper are composed of the following by mass percentage: pigment 3-10% , dispersant 1‑5%, humectant 1‑3%, organic solvent 20‑30%, surfactant 0.2‑1.5%, pH adjuster 1.5‑3%, bacteriostatic agent 0.5‑2%, and the balance is to Ionized water. The ink of the invention can be sprayed from a piezoelectric inkjet printing machine to a low-gram weight thermal transfer paper, and digitalized by a thermal sublimation process. The ink has good fluency, color fastness, and good fabric feel.

Description

technical field [0001] The invention relates to a disperse dye ink for thermal transfer printing of thin paper and a preparation method thereof, belonging to the technical fields of organic chemistry and textile printing and dyeing. Background technique [0002] At present, the inkjet inks used in textile printing mainly include reactive dye inks, disperse dye inks, acid dye inks and pigment inks. Sublimation ink is suitable for the printing of chemical fiber textiles. The process is to print the pattern on the thermal transfer paper with a wide-format printer or industrial printing machine, and then transfer the pattern to the chemical fiber textile fabric by heating transfer. At present, the disperse dye inks used in the market can only adapt to the thermal transfer paper with a certain thickness requirement, and have higher requirements for the weight of the paper (the current use is 80g paper). Under the current general trend of energy saving and environmental protectio...
