UV-cured pigment/latex dispersions were prepared via miniemulsion polymerization, and further applied to formulate UV-cured pigment/latex inks for textile inkjet printing. FTIR, TEM and TGA results proved that the pigment was embedded into the latex. The increase in colorfastness of printed fabric indicated that the encapsulation layer of UV-cured pigment/latex could be enhanced by increasing the amount of styrene in polymerization. In addition, the prepared UV-cured pigment/latex inks were found to have excellent stability and jettability, and the printed cotton fabric showed high colorfastness and softness after UV irradiation. SEM images illustrated that the UV-cured pigment/latex inks formed a separate film on cotton fabric which was unlike the commercial pigment ink forming a continuous film. This research combined the strengths of both UV-cured technology and miniemulsion polymerization. © 2014 Elsevier B.V. Source

A core-shell latex comprising poly(butyl acrylate) as core and poly(styrene-methyl methacrylate) as shell was synthesized by emulsion polymerization using allyloxy nonylphenoxy propanol polyoxyethylene ether ammonium sulfonate (ANPS) as emulsifier. Transmission electron microscope, differential scanning calorimeter, and thermogravimetric analyses suggested the prepared latex had a core-shell structure. The particle size of the core-shell latex was about 102.8 nm with a molar ratio of butylacrylate, methyl methacrylate, and styrene at 6: 2: 2, a mass ratio of ANPS and monomers, ammonium persulfate and monomers at 15% and 1.0%, respectively. The core-shell latex showed high centrifugal stability and excellent freeze-thaw stability. The clogging nozzle rate of the pigmented ink containing 20 wt % core-shell latex was small, whereas the printed fabrics with this pigmented ink exhibited high rub and washing fastness. © 2012 Wiley Periodicals, Inc.

Carbon black/latex composites were prepared by the method of miniemulsion polymerization for use in coloration of lyocell. The encapsulation of carbon black with the latex was confirmed by transmission electron microscopy (TEM), Fourier transforms infrared spectra (FTIR) and thermogravimetric analyses (TGA). Experimental results showed that a dispersion of the carbon black/latex composite with excellent freeze-thaw stability was achieved when polymerization was performed with the addition of carbon black, ammonium persulfate (APS) and methyl methacrylate (MMA) at a mass ratio of 40:1:200. The carbon black/latex composite dispersion was shown to have excellent miscibility with lyocell spinning solution which enabled a cellulose membrane to be well prepared, and the carbon black/latex composite dispersion content of 3% was adequate to produce the cellulose membrane with maximum color strength. This study provides new insight into spun dyeing of lyocell with the carbon black/latex composite dispersion. © 2013 Elsevier B.V. Source

A carbon black (CB)/latex composite was prepared by the method of miniemulsion polymerization for use as a colorant for spun dyeing of regenerated cellulose fibers. Analysis of experimental results revealed that the CB/latex composite had a small particle size and a narrow particle size distribution which were important to ensure a stable dispersion being later added to spinning solution. A good stability of the prepared CB/latex composite dispersion in the spinning solution indicated that it was highly possible to use the CB/latex composite as a colorant for spun dyeing of regenerated cellulose fibers. When a 3.5% mass ratio of CB/latex composite to cellulose was used for spun dyeing, the spun-dyed fibers had the highest tensile strength, breaking elongation and color strength. The rubbing and washing color fastnesses of spun-dyed regenerated cellulose fibers could satisfy requirements of most textiles. This study provided a new insight into producing spun-dyed regenerated cellulose with a novel colorant. © 2013 Elsevier Ltd. Source

A novel polymer-encapsulated C.I. Pigment blue 15:3 dispersion has been developed through emulsion polymerization approach by a polymerizable dispersant. The encapsulation process involves three steps: predispersing C.I. Pigment blue 15:3 using allyloxy nonyl-phenoxypropanolpolyoxyethyleneetherammonium sulfonate (ANPS) as dispersant and emulsifer, emulsifying with the addition of comonomers, and polymerizing comonomer and ANPS. The character of polymer-encapsulated pigment has been examined in detail using dynamic light scattering (DLS), Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM), thermogravimetric analysis (TGA), X-ray diffraction (XRD), and contact angle analysis (CAA). Results indicate that a polymer encapsulation layer is formed on the surface of pigment and the thickness of the encapsulation layer can be modulated by changing the amount and the structure of comonomer. The polymer-encapsulated pigment dispersion has enhanced stabilities to centrifugal force, temperature, pH value and electrolytes. © 2011 Elsevier B.V. Source
