Surface activation of viscose textiles via air, argon, and oxygen dielectric barrier discharge plasma: Influence of peak voltage

Abstract

This paper discusses the use of atmospheric pressure dielectric barrier discharge (DBD) plasma treatment to enhance the surface qualities of viscose fabrics. The study explores the effects of different plasma gases, discharge voltages, and exposure times on the treated fabrics. The findings emphasize the importance of optimizing the plasma's peak voltage to achieve desired surface treatment outcomes. The document also presents data on color strength, wettability, color fastness, and tensile strength of the treated fabrics, as well as SEM analysis of surface morphology and chemical analysis using FTIR and EDX. The results show that treatment at a peak voltage of 11.83 kV is more efficient, except for the tensile strength which is enhanced at a peak voltage of 8.92 kV. The oxygen plasma treatment significantly improves the color strength, which exhibits an increase from 11 to 18. The intensified color was attributed to the significant influence of electrostatic interactions between the charged hydroxyl groups of the oxygen plasma treated viscose textiles and the dye molecules, which enhance the printability. The oxygen dielectric barrier discharge plasma exhibits a higher ability to enhance the properties of textiles when compared to air and argon plasmas. This study presents a sustainable, economical, secure, and ecologically friendly approach to explore new fabrics for specific uses.
