One-Bath Pretreatment for Enhancing the Color Yield and Anti-Static Properties of Inkjet Printed Polyester Using Disperse Inks

Abstract

This paper presents a simple and economical method for preparing durable anti-static functionalized inkjet prints by using P[St-BA-F6]—novel antistatic agents synthesized by an oxidative polymerization of styrene, butyl acrylate, and allyl alcohol polyether F6. The P[St-BA-F6] was characterized by gel permeation chromatography and Fourier transformation infrared spectroscopy. One bath pretreatment solution containing P[St-BA-F6] and pentaerythritol tetraacrylate (PETA) were applied to polyester fabrics before inkjet printing, in order to enhance the color yield and the anti-static properties. The pretreatment conditions, including the concentrations of P[St-BA-F6], curing temperature, and time, were optimized based on inkjet printed polyester fabrics. SEM (scanning electron microscope), XPS (X-ray photoelectron spectroscopy), XRD (X-ray diffractometer), TG (thermogravimetric), and DSC (differential scanning calorimetry) examined the fabrics. The results showed that the treated PET fabrics exhibited good applied performances, such as higher color yield, better dry rubbing fastness, lower electrostatic voltage, and durable anti-static properties, even after washing 10 times. These results can be attributed to alcohol polythene group (F6) and allyl group (PETA). PETA can be cross-linked with P[St-BA-F6] and PET fiber. The thermal stability of the treated fabric was lower than that of the untreated fabric, owing to the presence of resin film on the fiber surface.

Influence of aminopropyl/vinyl/silsesquioxane post‐treatment on the colour performance of pigment‐based inks on ink‐jet‐printed polyester fabrics

“…They have numerous advantages concerning dye-based inks, for example, the simplicity of the process, lower production costs, better profitability, improved colour prediction, higher water, and light fastness. 12,13 Research and development pertaining the improvement of colour performance of pigment-based inks contained the conventional binders have been attempted by many researchers, including the application of various amino compounds, 14 chitosan 8,10,15,16 and its derivatives 8,14,17 ß-cyclodextrin and citric acid, 18,19 ink coagulants and acrylic resin for ink anchoring to the substrate. 20,21 However, the pretreatments components, just as the commercial textile binders which are incorporated in the ink formulations, might lead to the deposition of a high thickness of adsorbed layers with a higher increase in the total stiffness.…”

Formulation and characterization of pigmented inkjet inks containing aminopropyl/vinyl/silsesquioxane for jet printing onto polyester fabrics

“…Research and development pertaining to the advancement of color performance of pigment-based inks containing the ordinary binders has been attempted by many researchers, including the application of various amino compounds (Phattanarudee, Chakvattanatham and Kiatkamjornwong, 2009), chitosan (Choi et al , 2005; Yuen et al , 2007; Nasar H. et al , 2011; Cao et al , 2019) and its derivatives, ß -cyclodextrin, citric acid (Chen et al , 2012; Zhao et al , 2017; Cao et al , 2019), ink coagulants and acrylic resin for ink anchoring to the substrate (Koo et al , 2006; Ugur Koseoglu, 2019). Be that as it may, the pre-treatment components, just as the commercial textile binders, which are incorporated in the ink formulations, might lead to deposition of a high thickness of adsorbed layers with higher increment within the total stiffness.…”
