| dc.description.abstract | Plasma is highly ionized gas, which is also regarded as a ''fourth state'' of matter. In recent years it is used for textile surface treatment. It obtained advantages over wet process because of drastic reduction of pollutants and cost reduction for effluent treatments. This work discusses the use of atmospheric Diffuse Coplanar Surface Barrier Discharge (DCSBD) plasma on the surfaces of special fibers. Special fibers used were Kevlar, Twaron, Dyneema (Superstrong polyethylene) and Carbon/Kevlar blend. These fibers have special applications for example in aerospace, ballistic, building and sport. The common characteristic in them is high strength; however, they have low surface energy which makes them hydrophobic. The overall objective of this research is to see the effect of plasma on the surface of special fibers. Oxygen plasma creates hydrophilic chemical groups on the fibers surface through the process of oxidation. The literature reveals that special fibers have hydrophobic surfaces because of their crystallinity structure which results from covalent bonds. In this paper, wettability, contact angle, Scanning Electron Microscopy and FTIR results have been utilized to comprehend the effect of plasma on the fibers surfaces. | en |
