Abstract: Abstract: A range of oxygen plasma treatments has been used to modify the surfaces of woven and fibrous wool samples. The resulting chemistry and composition have been characterised using X-ray photoelectron spectroscopy (XPS). The extent of oxidation of di-sulphide bonds to sulphur (S"'), in the form of sulphonic acid groups (-SO,H), by the plasma is shown to be only about 20-30 % compared to 100 % using a conventional wet chlorination process. However, the plasma does appear to react with surface carbon of …
