Effect of the modified dispersing agent and milling time on the properties and particle size distribution of inkjet ink formulation for textile printing

Abstract

Purpose This paper aims to study the effect of the new modified dispersing agent, milling time of the properties and particle size distribution (PSD) of inkjet ink formulation for polyester fabric printing. Design/methodology/approach The study’s methods include preparation of different formulations of textile inkjet inks based on different types of dispersing agents, then applying and evaluating the prepared formulations on the polyester fabric. The properties of the prepared ink formulations were analyzed by measuring viscosity, surface tension and particle size. The current work is including the study of the effect of using different doses of different dispersing agents and the milling time on their characteristics. Also, the study was extended to evaluate the printed polyester by using the prepared inks according to light fastness, washing fastness, alkali perspiration fastness and crock fastness. Findings The results showed that the used dispersing agents and the different milling time enhanced the viscosity and dynamic surface tension in the accepted range, but it was largely cleared in the PSD which tends to perform the inks on the printhead and prevent clogging of nozzles. Light fastness, washing fastness, alkali perspiration fastness and crock fastness gave good results in agreement with this type of inkjet inks for textile printing. Research limitations/implications In this work, good results were obtained with this type of dispersing agent for inkjet ink formulations, but for other dispersing agents, other tests could be performed. The inkjet ink could also be formulated with other additives to prevent clogging of nozzles on the printhead. Practical implications These ink formulations could be used for printing on polyester fabric by the inkjet printing. Originality/value Recently, there was a considerable interest in the study of the effect of PSD on the inkjet inks to prevent clogging of nozzles on the printhead and to improve the print quality on the textile fiber.

Inkjet-Printed Silver Nanowire Ink for Flexible Transparent Conductive Film Applications

“…Ink droplets deposited on the surface of the substrate in a certain order form a printed pattern. Because the inkjet printing process needs to drop adjustable liquid on the substrate to achieve higher quality and pattern reproducibility, inkjet printing ink is one of the important factors to obtain high-quality patterns, and it is also the key to the popularization and application of ink-jet printing technology [ 20 , 21 , 22 , 23 ]. A stable printable conductive ink is usually obtained as conductive nanostructure in a suitable solvent or mixed solvents containing various additives, including dispersant, wetting agent, moisturizer, defoamer, and leveling agent, etc.…”

Influence of different dispersants on the quality and stability of aqueous quinacridone magenta pigment dispersion for ink‐jet applications

“…These factors contribute to the increasing popularity of water-based pigmented ink-jet inks. 8 Water-based pigmented ink-jet inks create a large opportunity in the modern commercial printing industry. They are seen as more environmentally friendly because they pose low safety risks, providing, in many cases, an easier recycling process of printed materials.…”

“…[9][10][11][12][13][14][15][16] Choosing the proper dispersing agent and its optimum amount is critical in achieving proper pigment stabilisation, viscosity and colour strength, and was studied in different applications by other authors. 3,[8][9][10][11][12][13][14][15][16][17][18][19] The stability of the pigment dispersion is usually assessed by observing changes in the particle size, particle aggregation after storage, viscosity, pH and external appearance; for example, phase separation. 3 The gloss and optical density of printouts provide further important information.…”

New thiadiazol azo disperse dyes derivatives and their application as a colored material for silk screen-printing ink for printing on polyester fabric

“…Using a new textile inkjet ink formulation based on modified dispersing agent and milling time, 100% polyester fabric is printed; the study includes the effect of using different doses of the different dispersing agents and the time of milling on the physical and mechanical properties of the prepared inks. The study also extends to evaluate the printed polyester according to light fastness, washing fastness, alkali perspiration fastness and crock fastness (Abd El-Wahab et al, 2019). Disperse inks for direct inkjet printing of non-pretreated polyester fabrics were prepared and evaluated (Chengyong .…”

“…For usage in transfer printing procedures, specially created disperse dyes with precise molecular weight and sublimation qualities are used. The printing and dyeing of a polyester fabric with inks containing disperse dyes were done to test the color fastness of the resulting-colored samples (Abd El-Wahab et al , 2021). The fastness characteristics of dyed and printed polyester samples were determined to be very good to excellent and generally meet recognized consumer criteria (Kosolia et al , 2011).…”
