Is plasma wettable?
Plasma can treat materials that are too hydrophobic ( non wettable) or too hydro philic (wettable) for the application they are intended for. The process can be classified into two categories; atmospheric and low-pressure or vacuum, as both use energy to ionize gas. Corona atmospheric treatments are generally used to treat larger substrates, and can easily make commodity-grade polymers wettable to improve coating adhesion. Explore the advantages of corona treatments. Low-pressure plasma treatments incorporate a vacuum chamber instead of direct contact with an open electrical charge.
What is plasma treatment?
Plasma treatment generally is a term generally applied to vacuum plasma treatment although technically flame, corona, and atmospheric plasma [15–31] are also plasma treatments. Each of these plasma types has different characteristics and may have different treatment depths as well as resulting in a different final surface chemistry.

Why do acrylic fibers need plasma treatment?
Plasma treatment causes better surface wettability because of formation of carboxyl and amide groups on the fibers’ surface, which increases hydrophilic properties of the surface.
How does plasma treatment affect synthetic fibers?
The changes occur mainly on account of bombardment of electrons, ions, and neutrals and affect the material only over a range of a hundred to several thousand angstroms in depth. When polymer substrates are used, the main effects are in terms of etching (loss of weight), cross linking, oxidation, and other chemical reactions, depending on the type of gas. These changes affect several physical and chemical properties of polymers such as permeability, solubility, melting point, and roughness at the surface ( Mittal, 1983). Adhesion, printability, coloration (dyeing), and adsorption, which depend on wettability, are naturally affected by the plasma treatment.
What is plasma wool?
Plasma treatments of wool represent a most innovative approach to replacing chlorination stages in wool finish ing and to improving existing processes with special regards to an economical–ecological optimisation. The apparent potential of plasma technology for wool finishing processes led to the development of machinery allowing a treatment under atmospheric conditions for different fibre make-ups. This can be regarded as a large step towards industrial implementation that will help the wool industry to benefit in the near future from a technology that is extremely surface-specific, totally effluent free, and thus less destructive and more environmentally friendly. The implementation of plasma technology into the wool industry is closely connected to further developments towards larger-scaled machinery, allowing a cost-efficient treatment with special regards to a high material throughput, as well as to the development of highly efficient tailored auxiliaries for achieving special effects.
Is atmospheric plasma treatment more expensive?
This has meant that the use of atmospheric plasma treatment sources is increasing. The atmospheric plasma treatment tends to be a higher cost process as the power supply is more expensive and the consumption of helium also presents a higher running cost.
Is plasma treatment safe?
Plasma treatments are environmentally safe as they do not release toxic organic solvents and are easy to control; current, pressure and voltage being the main parameters. Moreover it is reproducible. However, in spite of this, plasma-aided technology is not considered as a viable one mainly because of the complexity of the processes involved during the plasma treatment [22] and ageing of the polymer after treatment. Different strategies have been explored for improving the wettability of polymers, and plasma treatment has a major role among others. Atomic Force Microscopy has emerged as a valuable tool providing insight into the structure and properties of polymers. Plasma treatments lead to the formation of radicals that promotes surface crosslinking or functionalization thereby improving the surface properties [23]. A comparison of surface modifications of carbon fiber using various techniques is presented by Sharma et al. [24]. The atomic force microscopic images ( Fig. 11.10) show the effect of the various surface modification techniques on the surface of the carbon fibers.
