Inkjet Printable and Self-Curable Disperse Dyes/P(St-BA-MAA) Nanosphere Inks for Both Hydrophilic and Hydrophobic Fabrics

Abstract

Low-water-soluble disperse dyes possess a broad color gamut and good durability, but they need chemical or physical modification before being used in inks and can only be applied to several kinds of hydrophobic fabrics. In this work, disperse dyes/P(St-BA-MAA) nanospheres (known as DPN) absorbed by sodium nitrilotriacetate (known as NTA@DPN) were prepared and applied into ink formulations, which exhibited high dye fixation, long-term stability and self-curable ability without addition of any binder. Transmission electron microscopy (TEM) images showed the nanospheres have homogeneous core-shell spherical shape and the average diameter increased by 20.6 nm after coloration. X-ray diffraction (XRD), Fourier transform infrared spectrum (FTIR), and differential scanning calorimetry (DSC) measurements illustrated the interaction between dyes and nanospheres and indicated that the colored nanospheres contained both dye molecules and crystalline dyes. The Zeta potential and particle size measurements demonstrated that the dispersion stability was improved when sodium nitrilotriacetate (NTA) was absorbed onto DPN. The rheological behavior of the NTA@DPN inks was Newtonian and desired droplet formation was achieved at the viscosity of 4.23 mPa·s. Both hydrophilic cotton and hydrophobic polyester fabrics were cationic modified before used, which had an excellent image quality and desired rubbing fastness after inkjet printing. Scanning electron microscope (SEM) images showed NTA@DPN formed stable deposits on the surface of modified fibers and could self-cure to form continuous film coating on the fiber surface after being baked at 150 °C without addition of any binder.

Effect of ethylene glycol and its derivatives on the aggregation properties of reactive Orange 13 dye aqueous solution

“…Research on the aggregate structure of dyes especially in favourable areas like solar power generation (cyanine dyes), [1][2][3][4] dyeing and printing [5][6][7][8] has always remained a hot topic for researchers to work on so that a number of problems can be eliminated. In particular, the aggregation behaviour of dyes creates a problem in the preparation of homogeneous dye solutions or inks for dyeing and printing of different textile substrates through affecting the process of dye adsorption and diffusion.…”

Interaction of Reactive-Dye Chromophores and DEG on Ink-Jet Printing Performance

“…Digital ink-jet printing technology has been applied in many fields because of its incomparable advantages, such as low cost, facility, celerity, and ecofriendliness [1][2][3][4][5][6][7][8][9][10]. Reactive dyes are widely used for cotton-fabric dyeing in ink-jet printing techniques due to their bright color, excellent performance, and good applicability [2,[11][12][13][14][15].…”

A Numerical Investigation on the Collision Behavior of Polymer Droplets

“…The collision dynamics of droplets in a gas environment are of great importance in the industrial processes related to spraying, such as spontaneous combustion gel propellants in missile propulsion systems [1], 3D inkjet printing in textile printing [2][3][4], and polymer-solvent sprays in chemical pharmaceutical engineering [5]. In particular, in order to develop better-performing products, the surfactants are often used to change the surface tension of the fluid without changing other properties.…”
