Technical Field

The invention relates to the field of ink-jet printing ink, in particular to high-temperature direct-injection dispersion ink and a preparation method and application thereof.

Background

The digital textile printing ink used in the market at present is mostly medium-low temperature type thermal sublimation ink, and has some defects compared with high-temperature dispersion ink: 1. and (3) infiltration: the dispersed thermal transfer printing ink is jet-printed on thermal transfer printing paper and then transferred onto the fabric, only the surface of the fabric is colored, and the condition that the yarn turning is exposed to white is often found in a finished product after printing. The high-temperature dispersion direct-injection ink is printed in a direct-injection mode, the ink is directly sprayed and printed on the textile fabric, the ink can permeate into the fabric, and the textile fabric is dyed more deeply after steaming and fixation, so that the condition that the turned yarn is exposed to the white is avoided. 2. Hand feeling: the heat-dispersing transfer printing is carried out at a high temperature of more than 200 ℃, the printed fabric is hard in hand feeling, particularly, the velvet and wrinkle fabrics are completely disappeared after printing, and the quality of a printed finished product is seriously influenced. The high-temperature dispersion direct ink jet adopts steaming color development, and the hand feeling of the finished fabric after printing is basically unchanged. 3. Color fastness: the dye used for the disperse thermal transfer printing is medium-low temperature type disperse dye, the sublimation temperature is low, the color fastness on the fabric, particularly the sublimation fastness, can not meet the requirement of a high-quality order, the high-temperature type disperse dye is adopted by the high-temperature dispersion direct-injection ink, the sublimation fastness is high, and the secondary sublimation phenomenon can not occur basically.
