The purpose of this study is to investigate the reflectance behavior of printed cotton/polyester fabrics with pigment and vat dyes printing pastes containing different loads of TiO2 nanoparticles and carbon black.
It was found that the reflective behavior of printed fabrics in the NIR region with vat dyes is higher than with pigment dyes. In addition, according to the values for TiO2 nanoparticles and carbon black in the printing pastes, the NIR reflectance reduces.
Increasing both TiO2 nano particles and carbon black in the printing paste did not negatively affect the light, rubbing, and washing fastnesses of the fabrics, and all were noticeably good.
Both TiO2 and carbon black particles could increase the visual color difference (View the MathML source) of samples compared to samples without them.
