Chitosan/Disperse Dye Nanoparticles for Concomitant Printing and Antibacterial Finishing

Abstract

Innovation concerned with hybridization of nanosiezed chitosan with nanoparticles of a disperse dye under the onset of sonication was studied. Three techniques were outlined describing the nanoparticles preparations of chitosan, disperse dye and chitosan /disperse dye nanoparticles. Thus obtained hybrid nano colorant auxiliary was found to possess different hydrophobic/hydrophilic characteristics as well as variable color intensity depending upon the ratio of the disperse dye in the chitosan/dye mix. When applied to textile fabrics (flax, polyester, and polyester/flax blend) as per the pigment printing technique, the nano colorant hybrid display multifunction antibacterial activity and coloration ability. The prepared nanoparticles of chitosan/ disperse dye were characterized using TEM and XRD. The coloured hybrid was applied in textile printing using silk screen technique. The printed samples were evaluated by measuring colour strength, fastness properties, means of print fixation and antibacterial activity.
