Abstract
The surface of cotton fibre was modified by atmospheric pressure plasma treatment (APPT), using gas as the carrier. Effects of variations in four operational parameters, discharge power, oxygen flow rate, jet-to-substrate distance and speed of the jet movement were examined. Morphology of surface of cotton fabrics was examined by generating Scanning Electron Microscopy (SEM) images. Elementary composition of the surface of the fabric was examined by X-ray Photoelectron Spectroscopy (XPS) and Fourier Transform Infrared Spectroscopy-Attenuated. Total Internal Reflectance (FTIR-ATR) was used for examining functionality of the surface. In this study, we revealed that the operational parameters would physical and chemically after the surface characteristics of the cotton fibre. Physically, cracks and grooves were noted in the cotton fibre surface after APPT. Chemically, the oxygen content in the cotton fibre surface was increased after APPT. When the O/C ratio is taken into consideration, the surface oxidation was a steady effect in applying APPT for treating cotton fibre in this study.
Highlights
Surface characteristics of fibres and fabrics can be altered by plasma treatment and this does not much impact The bulk properties of fibres and fabrics [1,2]
When The O/C ratio is taken into consideration, The surface oxidation was a steady effect in applying atmospheric pressure plasma treatment (APPT) for treating cotton fibre in this study
When The O/C ratio is taken into consideration, The increase in jet moving speed oxygen flow rate give similar O/C ratio which means than The oxidation is a steady effect in applying plasma for treating cotton fibre in this study
Summary
Surface characteristics of fibres and fabrics can be altered by plasma treatment and this does not much impact The bulk properties of fibres and fabrics [1,2]. Precise effect of plasma treatment, i.e., The change it induces in characteristics of surface of The fabric, depends upon which gas is used in. The textile industry uses atmospheric pressure plasma treatment (APPT) quite extensively for altering surface characteristics of fabrics, one distinct advantage being that it is a continuous process [6,7,8,9,10]. In this study, we study The effects of APPT on fabric surface using atmospheric pressure plasma jet (APPJ) system. In The APPJ system four operational parameters, i.e., (1) discharge power; (2) flow rate of oxygen; (3) jet moving speed; and (4) jet-to-substrate distance, would be used The effect of these four operational parameters on The surface characteristics of cotton fabric would be evaluated instrumentally
