A nano-water-based thermal transfer ink suitable for high-speed printing with Kyocera nozzles

Abstract

The invention provides nano waterborne heat transfer printing ink applicable to the high-speed printing of a Kyocera ink-jet head. The nano waterborne heat transfer printing ink comprises nano color paste, propylene glycol, glycerol, pentadiol, a wetting agent, an emulsifier B, a sterilizing agent and deionized water, wherein the color paste comprises salt-free refined dispersing dye, a dispersingagent A, a dispersing agent B, glycerin, a sterilizing agent, a defoaming agent and deionized water. The nano waterborne heat transfer printing ink applicable to the high-speed printing of a Kyoceraink-jet head has the advantages that the ink is good in standby performance, stable in long-term printing performance, free of excessive ink marks, good in color stability and reducibility, excellentin performance such as washing resistance, dry and wet scratch resistance and sun resistance, capable of satisfying digital printing requirements (the dry and wet scratch resistance reaches level 4-5,the washing resistance reaches level 4-4.5, and the sun resistance reaches level 3.5-4.5), environmentally friendly and nontoxic and passes REACH and Intertek certification, and the ink has good compatibility with the Kyocera ink-jet head and is widely applicable to the printing of a printer with the Kyocera ink-jet head (KJ4B-300DPI).

Description

technical field

[0001] The invention belongs to the technical field of ink-jet inks, in particular to a nano water-based thermal transfer printing ink suitable for high-speed printing in Kyocera nozzles and a preparation method thereof. Background technique

[0002] Digital transfer printing, also known as digital thermal transfer printing or digital inkjet transfer printing, is to use digital technology to print and process textiles containing man-made chemical fiber components. The processing process is simply to input images into The computer, after editing and processing by the printing software system, forms the required pattern, and then controls the printing by the output software, prints various special thermal transfer inks on the paper, and then transfers them to the chemical fiber after heating and fixing at 180-220°C On the fabric, printed textiles with high-precision patterns are obtained. The washing fastness is 4-4.5, and the dry and wet rubbing is 4-5, which ...
