Color and fastness properties of printed with reactive dye viscose fabrics and fixed with radio frequency energy

Abstract

In this study, causticized and un-causticized viscose fabrics were printed with reactive dye. Fixation of printed viscose fabrics with reactive dyes was only possible under steaming conditions. Reactive printed samples (untreated and causticized) were treated with radiofrequency and steam combination. Color efficiencies of the samples fixated with radiofrequency and steam combination were compared with a conventional steam, at 102°C for 10 minutes. An application of steam combination with radiofrequency energy on causticized fabrics did not lead to a higher color performance in comparison to the color performance resulting from classical steaming method. However similar values were obtained for shorter durations. There was no negative effect of fixation with radiofrequency and steam combination on color fastness properties.
