Eco-Friendly Preparation, Characterization and Application of Nano Tech Pigmented Inkjet Inks and Comparison of Particle Size Effect and Printing Processes

By acknowledging the importance of Nano tech inkjet inks, the “top down” method of nanotechnology was followed for manufacturing the Nano tech inkjet inks of pigment Yellow 14 powder 100 % dried and pigment Blue 15.1 (100 % dried powder) and then characterized for their particle size, zeta potential, purity, viscosity, surface tension, foam, pH, engineering stability, shear thinning, by using different spectroscopic, microscopic and particle size analyzing techniques. Both of the inks were applied on 100 % singed, desized, scoured, bleached and pretreated cotton weight 134.4g/m2 through Monna Lisa Evo TRE printer EPSON (Model No EVO TRE 16). The printed samples were dried and cured 150 °C for 5 minutes. The samples were evaluated for their color fastness to light, rubbing, washing, laundering, and K/S value, by using relevant AATCC and ISO’s methods. Same powders were emulsified and applied on same cotton through traditional rotary screen printing method, dried, cured at 150 °C for 5 minutes and evaluated for their fastness properties for comparative study. It was concluded that by promoting the use of green chemistry and nanotechnology, the resulted benefits include better print, increased light fastness and color gamut, reduced chemical, energy and water consumption along with environmental friendly effectiveness.
