Research on Disperse Dye Paste for Digital Printing
A dispersant with novel structure was designed and synthesized for digital dispersion color paste,and its effect on the dis-persion performance was discussed.The results showed that in this dispersion system,average particle size D50 of the color paste was below 120 nm,and the thermal storage stability and filtration performance were good.Compared with conventional dispersants,this dispersant was characterized by its low dosage,environmental friendliness,and economy.The viscosity of the color paste was less than 2 mPa·s,which could meet various ink compatibility requirements.
