“…Plasma treatments, which utilize a gaseous electrical discharge, are reported to be surface specific for wool fibers (Kan et al, 2004) and offer the potential of simple, clean, solvent-free, and inexpensive treatment (Thomas et al, 2005;Körner & Wortmann, 2005;Klausen et al, 1995;Kalkbrenner et al, 1990). All these treatments (Thomas, 2007;Wakida et al, 1993Wakida et al, , 1996Wakida et al, , 1994Lee et al, 2001;Höcker et al, 1994;Yoon et al, 1996;Jocic et al, 2005;Kan et al, 1998;Kan & Yuen, 2008;ElZawahry et al, 2006;Kan, 2006) have shown to invariably increase the rate of uptake of dyes by wool. Some studies have revealed that little or no physical change to the surface structure of wool fibers results from treatment with plasma, whereas others have found significant damage (Thomas, 2007;Wakida et al, 1993;Yoon et al, 1996;Kan, 2006;Erra et al, 2002).…”
