Pigmented inkjet inks for printing on cotton, polyester, cotton/polyester blend, and silk were prepared by changing types of resin. The resins were investigated in terms of emulsion stability, water uptake, and Young’s Modulus of the resin films. The pigments were incorporated in the emulsions and other compositions in the inkjet ink also gave colored inks. Viscosity, surface tension, and pH of the inks were measured and adjusted to meet the requirement of the printer. The four-color inks were printed on nontreated fabrics by a piezo-driven inkjet printer. The printed fabrics were investigated for the depth of ink penetration, stiffness, and crockfastness. This research elucidates the relationship between hydrophilic/hydrophobic properties of the fabrics, which affects the quality of prints.
