Abstract

We attempt to recover the surface properties of wool fibers damaged by physical and/or chemical treatment. For this purpose, two kinds of damaged wool fabric samples are prepared, one damaged by corona discharge treatment and the other oxidized with dichloroisocyanuric acid. We confirm that these treatments decrease the content of covalently bound fatty acids and change the fiber surface properties. To recover the surface properties of damaged wool, a fatty acid chloride, stearoyl chloride, is used to treat both damaged samples. The content of covalently bound fatty acids in treated samples recovers to some degree, and the surface characteristics of the treated wool fibers also recover from hydrophilic to hydrophobic. We also evaluate some mechanical properties with the KES-FB method, and we find they recover almost to the level of the original wool fabric sample.
