In the research, pigmented inkjet inks for fabric printing on cotton, polyester, cotton/polyester blend, and silk were prepared by changing types of ink binder. The binders that could eject droplets of the inks were acrylate and polyurethane emulsions. Mechanical stability of the emulsions, and water uptake of binders were tested for ink ejections. Young’s modulus, and hardness of the free binder films were tested for their print quality. The four color inkjet inks were printed on nontreated fabrics by a piezo-driven inkjet printer. The printed fabrics were investigated for stiffness and crockfastness. The cotton fabric was treated with alumina in poly(vinyl alcohol) solution. The treated fabric was then printed by the above inks. Color saturation and crockfastness of the printed fabric were determined. Properties of the inks were found as follows: viscosity, 1-3 mPa s; surface tension, 57-59 mNm-1; and pH, 8-9. The acrylate binder in the ink yielding the high mechanical stability and water uptake renders renders the better ink ejection. The printing results indicated that the polyester fabric printed with all the binders gave the highest stiffness, whereas the printed cotton yielded the less stiffness. Considering the different binders and stiffness, we found that the binder stiffness affected most on polyester fabric. The higher modulus of the binder produced the greater stiffness of the polyester fabric. The stiffness of other three printed fabrics did not differ much. The resulting crockfastness of the fabrics depended on the amount of ink deposited, binder hardness, and fiber strength. The more hydrophilic fabric provided the lower crockfastness than the polyester fabric with less hydrophilicity. The polyurethane binder gave the greater crockfastness on the polyester fabric. When printing with the polymer of acrylate, it produced good crockfastness on all fabrics. The attribute of surface treatment on cotton fabric rendered the higher color saturation, but the less crockfastness compared with the nontreated surface. The treated surface of the fabrics reduced ink wicking on the fabrics. This research elucidates the relationship between hydrophilic/hydrophobic properties of both the binders, and the fibers, and qualities of the printed colors of pretreated fabrics.
