Colour Properties of Plasma-Induced Ozone Fading of Cotton Fabric

Abstract

This study concerned with colour fading of cotton fabric by plasma-induced ozone treatment. Cotton knitted fabrics were dyed with reactive dye of red colour with a depth of 0.5% and were subjected to ozneo generated by a plasma machine for colour fading. In order to investigate the colour properties of the plasma-induced ozone treated cotton fabric. The plasma-induced ozone treatment was conducted with different parameters: (i) air concentration = 10%, 30%, 50% and 70%; (ii) water content in fabric = 35% and 45% and (iii) treatment time = 10 minutes, 20 minutes and 30 minutes. After the plasma-induced ozone treatment, the colour properties of the fabric were measured by spectrophotometer under illuminant D 65 to obtain the CIE L*, CIE a* and CIE b* values.
