Effect of Surfactants as Dispersing Agents on the Properties of Microemulsified Inkjet Inks for Polyester Fibers

The preparation of microemulsified disperse inkjet inks was carried out and the effect of the surfactant used as dispersing agents on the properties of the inks was studied. The dispersing agents used were anionic conventional and non-conventional surfactants and a gemini type surfactant. The properties studied were surface tension, pH, conductivity, viscosity and the particle size distribution. The use of the gemini type and the two non conventional surfactants even in submultiple amounts resulted in a significant increase in the ink stability.
