Improvement the Levelness of Viscose-Cotton Blended Fabric Dyed with Reactive Dye Using Low Temperature Air Plasma

Abstract

Abstract Viscose-Cotton (50/50) blended fabric has different dye-uptake properties caused by uneven dyeing. To improve the levelness of dyeing on viscose-cotton blended fabric, air plasma was used through modification of surface structure. Air plasma was treated by air pressure 0.15 Tor with different plasma treatment times (2,4,6,8 and 10 min) maintained. In addition, FT-IR, XRD and SEM analysis confirmed the crystalline and amorphousness structure of different plasma treated blended fabric. The effectiveness of the air plasma treatment was assessed based on the exhaustion (%) and levelness (%). Air plasma treated viscose-cotton blended fabric was measured by instrumental method and image J analysis. Air plasma treatment afforded superior dyeing levelness compared to untreated viscose-cotton blended fabric. Moreover, air plasma treatment is a sustainable process in terms of levelness properties on viscose-cotton blended fabric.
