Emphasizing the Parametric Study of Effects of Atmospheric Pressure Plasma Treatment on the Wettability of Cotton Fabric | Chapter 4 | Current Perspectives on Chemical Sciences Vol. 4

Wettability plays a very important role in improving processes such as dyeing and printing in the manufacturing of textiles. Although the well-prepared cotton fabric has very good wettability, the subsequent dyeing and printing processes can be effectively improved by further enhancing its wettability. Plasma treatment, especially atmospheric pressure plasma treatment (APPT), which is a continuous process, is now attracting industry interest. In this analysis, we investigated the effect of APPT on the wettability (in terms of wickability and wetting area) of cotton fabric under four operational parameters: (1) discharge power; (2) oxygen flow rate; (3) jet travel speed; and (4) jet-to-substrate distance. Experimental findings showed that, in affecting the wettability of the cotton fabric, the four parameters communicate with each other. Generally speaking, in terms of wickability and wetting area, the atmospheric pressure plasma treatment may further improve the wettability of cotton fabric. Experimental findings show that, in terms of their impact on the wettability of the cotton fabric, operational parameters interact with each other. This study therefore provides important technical details and knowledge for the application of plasma atmospheric pressure treatment in textile manufacturing.

Advanced Studies on Surface Characterisation of Atmospheric Pressure Plasma Treated Cotton Fabric—Effect of Operation Parameters | Chapter 1 | Current Perspectives on Chemical Sciences Vol. 4

Plasma treatment can modify the surface characteristics of fibres and fabrics and this does not have much effect on the bulk properties of fibres and fabrics. The exact effect of plasma treatment, i.e. the change that it makes to the surface characteristics of the cloth, depends on the gas used in the treatment. The cotton fibre surface was modified by plasma atmospheric pressure treatment (APPT), using gas as the carrier. The effects of four operating parameter variations, discharge strength, oxygen flow rate, jet-to-substrate distance, and jet movement speed were examined. The surface morphology of cotton fabrics was investigated by Scanning Electron Microscopy (SEM) images. X-ray Photoelectron Spectroscopy (XPS) and Fourier Transform Infrared Spectroscopy-Attenuated studied the elementary composition of the surface of the cloth. To analyze the functionality of the surface, Total Internal Reflectance (FTIR-ATR) was used. In this analysis, we revealed that after the surface characteristics of the cotton fibre, the operational parameters would be physical and chemical. Physically, after APPT, cracks and grooves were noted in the cotton fibre surface. The oxygen content on the surface of the cotton fibre was chemically increased after APPT. When the O/C ratio is taken into account, there was a steady effect of surface oxidation in the application of APPT for the treatment of cotton fiber in this study.
