Preparation of color polymeric nanomaterials containing dispersed dye by sunflower oil synergy and color transfer property by digital inkjet printing

Abstract

The color polymeric nanomaterials containing highly dispersed dye molecules were designed and prepared by sunflower oil synergy microemulsion polymerization. The color nanoparticles can be applied to coat on the PET fabrics by digital inkjet printing technique. The sunflower oil as a dye solubilization and polymer plasticizer was used in the polymerization process. The structure and morphology of polymeric nanoparticles containing dispersive dyes were characterized by Fourier transform infrared spectrum (FT-IR), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and X-ray powder diffraction (XRD) analysis. The color transfer properties from nanoparticle coating into PET fabrics by digital inkjet printing were discussed. Three color nanoparticles were homogeneous nanospheres with regular shape and size below 100 nm. The nano-balls were swelled by sunflower oil. The dye is evenly dispersed in colloidal nanoparticles. The color transfer rate of three nanoparticles containing disperse dyes with 2.43% oil by digital inkjet printing method were 97.1%, 95.3%, and 96.1%, respectively. The color transfer rates of three color nanomaterials with sunflower oil were obviously improved. The fastness properties of the PET fabrics printed with three nanoparticles with oil were excellent.
