Abstract
The formulated inks with desirable physical and chemical properties are of significance for inkjet printing, to endow the fabric with expected image quality and color performance. Here, various kinds of water-soluble alcohols are preferably selected and introduced into reactive ink with an objective to improve the physical and rheological properties of ink and print quality of cotton fabric. In this study, the effects of alcohols with different boiling points on the rheology properties, drying behavior, and storage stability of ink were extensively investigated. Moreover, the print image performance, including color strength, fixation rate, ink penetration, and outline sharpness, was evaluated. The results indicated that the inks containing glycerol, diethylene glycol, and triethylene glycol possessed slower evaporation rates, but the storage stability and the dye fixation value of these inks would be decreased. The addition of alcohols into the reactive dye ink could increase the ink penetration and reduce the line image quality. The ink containing 1,2-propanediol with a medium boiling point can effectively satisfy various properties of the reactive ink and improve the fixing rate and printing quality onto cotton fabrics. Furthermore, these findings shed light on the propriate selection of reactive ink with alcohols and provide valuable information for technicians and researchers working in the printing industry.
Highlights
Textile inkjet printing is one of the most cutting-edge technologies in the textile industry because it has provided several economic and environmental benefits, such as speed, flexibility, competitiveness, eco-friendliness, high print resolution, and rapid response to frequent style and color change with minimum downtime for change over.[1,2] In recent years, with the significant improvement in printing speed and image quality of inkjet printers, printhead manufacturing, and demands in the market for digitalization of print designs, textile printing has attracted increasing attention.During the printing process, tiny ink droplets are ejected from a small printhead and precisely impact specific locations of the fabric
Park et al.[3] discussed the effects of parameters on the inkjet print quality of lines printed on polyester fabric and found that the image quality depended on the fabric construction, finishing, and ink type
The aim of this work was to investigate the influence of the water-soluble alcohols with different boiling points on the ink properties and the image quality of cotton printed fabrics
