Abstract

The present study aims to prepare and evaluate white pigmented inks with home-made dispersing agent and investigate their physical and chemical characterization for inkjet printing on cotton fabric against white inks made by global dispersing agents, and focused on manufacturing of dispersing agent through the chemical reaction between glycerol mono oleate (GMO) and toluene diisocyanate (TDI). Subsequently, Gallic acid and modified succinic anhydride with PEG 600 which can be employed in water-based white pigmented inkjet inks. Fourier Transform Infrared Spectroscopy (FTIR) and Gel Permeation Chromatography (GPC) were employed to analyse the resultant dispersant and observe the advancement of the chemical reaction. In contrast with global available dispersants, an innovative constituent was developed to be used as an essential ingredient within white pigmented inkjet inks, featuring characteristics such as particle size distribution, dynamic surface tension, transmission electron microscopy (TEM), viscosity, and zeta potential. The investigation further encompassed the evaluation of the wash and crock fastness of the printed fabric utilizing the manufacturing inks. The obtained results indicate that the manufactured dispersing agent exhibited superior performance as compared to the industry benchmarks, particularly with regard to particle size distribution.
