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.

Inkjet printing technology shows many environmental advantages over the conventional dyeing and printing process, which enables the cost-effective short-run for production
This paper aims to explore the possibility for improving the color yield and the anti-static properties of Polyethylene terephthalate (PET) fabric by one-bath pretreatment of prior to inkjet printing
The a* value is almost unchanged, the b* value is a slight increase when the curing fixation temperature was 170–210 °C. These results reveal that the curing fixation temperature is a decisive parameter for the increase of the color yield
Summary
Inkjet printing technology shows many environmental advantages over the conventional dyeing and printing process, which enables the cost-effective short-run for production. It is because that the diffusion behavior of disperse dye ink and the weave density on untreated polyester (Polyethylene terephthalate (PET)) fabric exerts significant impact on the printing accuracy and quality [1,2]. Plasma treatment is becoming more and more popular for the surface modification of textiles It only changes the outermost layer of a material without interfering with the bulk properties. It offers the advantage of greater chemical flexibility to obtain multifunctional textiles. The anti-static behaviors of the plasma treated PET fabrics can be greatly improved and an acrylic acid treatment can further enhance the anti-static properties of the specimens [7]
