“…The pigments are colored compounds that are insoluble in water, in the solvent (basic and acidic) and do not contain any group that can react with the textile fiber by means of a binder. They are commonly used in printing processes (pigment printing) [67, 68]. Organic pigments are largely benzoic derivatives and inorganic pigments (minerals) are derivatives of metals such as titanium, zinc, barium, lead, iron, molybdenum, antimony, zirconium, calcium, aluminum, magnesium, cadmium and chromium [69].…”

In the present review, we have been able to describe the different families of dyes and pigments used in textile finishing processes (Yarns, fabrics, nonwovens, knits and rugs) such as dyeing and printing. These dyes are reactive, direct, dispersed, indigo, sulphur and vats. Such that their presence in the liquid effluents resulting from the textile washing constitutes a serious risk, in the absence of their purification, for the quality of receiving aquatic environments. Indeed, the presence of these dyes and pigments can cause a significant alteration in the ecological conditions of the aquatic fauna and flora, because of the lack of their biodegradability. This has a negative impact on the equilibrium of the aquatic environment by causing serious dangers, namely the obvious dangers (Eutrophication, under-oxygenation, color, turbidity and odor), the long-term dangers (Persistence, bioaccumulation of carcinogenic aromatic products and formation of by-products of chlorination), mutagenicity and carcinogenicity.

“…The agglomeration of organic matter (dyes, pigments, etc.) in watercourses induces the appearance of bad taste, bacterial proliferation, pestilential odors and abnormal colorations [68, 71, 85, 86]. In such a way that coloration could be perceived with the naked eye from a mass concentration of dyes equal to 5 μg/L [17, 94].…”

“…Too high molecular weight may cause the polymer chain to back‐fold on themselves and this eventually leads to dispersion instability 6 . The soluble polymeric chain provides dispersion stability through steric hindrance and contribute to reduction of the milling viscosity, while the pigment anchoring groups such as amine or carboxyl could improve dispersibility of the pigment 11,12 . Lokhande et al highlighted benefits of polymeric dispersant such as shorter grinding time, good dispersion stability and better optical properties of the coating compared to monomeric dispersant 13 .…”

It is highly desirable to develop bio‐based products using sustainable materials and reduce dependence on petrochemicals. There are various reports on the use of sustainable materials in the synthesis of polymer resins, but research on the use of sustainable materials in development of coating additives such as polymeric dispersant is significantly lacking. Objective of this work is to produce fatty acid‐based polymeric dispersant using oleic acid in combination with butyl acrylate. The performance of the fatty acid‐based polymeric dispersant was benchmarked against commercially available and petrochemical‐based polymeric dispersant. The dispersants produced were characterized using spectroscopies (1H‐NMR and FTIR), thermal analyses (thermogravimetric analysis and differential scanning calorimetry), and molecular weight analysis. Application test was conducted to evaluate the effectiveness of the polymeric dispersant in titania pigment concentrate formulation which was tinted in nitrocellulose clear coating. Properties such as viscosity, fineness, gloss, optical properties, and storage stability were evaluated, and the result obtained shows that fatty acid‐based polymeric dispersant could disperse titania efficiently and produced coatings with good optical properties and excellent gloss retention. The carboxyl group from the incorporated fatty acid served as excellent pigment anchoring group, facilitating good orientation of dispersant on the pigment surface and promote excellent stability.

“…However, up to now, the preparation and application of disperse dyes in aqueous inks are still considered a dilemma. For example, surfactants or polymeric dispersants, or appropriate polymer encapsulation, are essentials because of their low dispersion stability (Lee et al , 2005; Zhang et al , 2012). To further improve the repulsive energy between nanospheres, non-ionic or ionic surfactants were used and reported (Ahmad et al , 2013; Romero-Cano et al , 1998; Jódarreyes et al , 2006).…”

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.
