The Preparation And The Application Research Of The Disperse Dye Inkjet Heat Transfer Printing Ink

Textile digital ink jet printing technology offers benefits such as flexibility, short process, clear patterns and cleanliness, etc. It adapts to current textile market which requires individuation, small batch production, fast delivery and eco-friendliness. So textile digital ink jet printing technology is considered to be one of the key technologies of textile industry in 21st century.Disperse dye offers benefits such as the low fabric cost fast good color fastness and transfer printing, etc. But there are also some current problems to be solved, such as processing difficulties, easy to plug, the high cost and the low dark degree of black. Dye ink and pigment ink all has literature reports at home and abroad.But disperse dye ink applied research is seldom reported.This topic first by wet ultrafine grinding of specific disperse dye,we get the liquid ultra-fine disperse dye that the particle size is small and the stability is relatively good. I analyzed some factors such as preparation process, structure and dosage of dispersants, milling equipment, etc. With nano particle and potentiometric analyzer, digital rotational viscometer and bubble pressure type dynamic surface tension meter, we have related characterization. The results show that, under the condition of best dispersant M grinding, when dispersant M with C.I. disperse red 60 at the best mass ratio of 10% grinding 8 h, particle size will reach 290 nm; When dispersant M with C.I. disperse yellow 54 at the best mass ratio of 20% grinding 13 h, particle size will reach 360 nm; When dispersant M with C.I. disperse blue 14 at the best mass ratio of 10% grinding 6 h, particle size will reach 300 nm; When dispersant M with C.I. disperse orange 25 at the best mass ratio of 15% grindingl2 h, particle size will reach 330 nm; When dispersant M with C.I. disperse green 9 at the best mass ratio of 20% grinding 11 h, particle size will reach 310 nm; When dispersant M with C.I. disperse violet93 at the best mass ratio of 10% grinding 8 h, particle size will reach 200 nm.Then the preparation of the three primary colors of super fine dispersion are blended to get black color for thermal transfer printing. And the preparation of the secondary colors of super fine dispersion are blended to get black color for thermal transfer printing. Finally we mix two black dispersion according to 1:1 for thermal transfer printing. We study the deep and dark effect. Then we use computer colour matching instrument to test. In view of this, with C.I. disperse red 60, C.I.disperse yellow 54 and C.I.disperse blue14 according to the proportion of 1:0.7225:0.5062, we can get black.And with C.I. disperse orange 25, C.I.disperse disperse green 9 and C.I.disperse violet 93 according to the proportion of 1:1.6974:1.3063, we can get black.Single tinted spell mixed disperse black thermal transfer polyester fabric color characteristic value is influenced obviously by temperature, time.And black degree is not deep. With three primary colors and the secondary colors are blended according to the proportion of 1:1 to get black color for thermal transfer printing. Black will be deeper. But thermal transfer polyester fabric color characteristic value is still influenced obviously by temperature, time.
