Effect of additives on Colloidal properties and printing performance of disperse dye blue inks for inkjet printing

Abstract

Disperse dye inks as one of the main colorant materials for polyester fiber in textiles inkjet printing have attracted more and more people's attention. In this paper, the nanoscale disperse dye blue dispersion was prepared, and further the effects of additives on colloidal properties and printing performance of disperse dye blue ink were investigated. Particle size distribution revealed that particles were small and uniformly distributed into aqueous media. Amount of polyols, defoamer and surfactants have significantly influence on colloidal and printing performance of the disperse dye blue ink. The optimal formulation of disperse dye blue ink was obtained with polyol 27 wt%, surfactant 1.0-1.2 wt%, and defoamer 0.25 wt%.
