Dielectric barrier discharge type of plasma reactor was used for the low-temperature plasma (LTP) treatment of the wool fabrics. Air was used as the non-polymerizing gas for the plasma treatment at different time intervals. Low-stress mechanical properties of the treated and untreated wool fabrics were evaluated using Siro-fast technique which revealed that the tensile, bending, compression, shear, dimensional stability and surface properties were altered after the LTP treatment. Other properties such as thermal conductivity, thermal resistance and pilling propensity were also evaluated. The surface topographical changes of the wool ﬁbres after LTP treatment were analysed by scanning electron microscopy. The changes in these properties are supposed to be related closely to the interﬁbre and interyarn frictional force and increased surface area of the ﬁbres induced by the etching effect of plasma.
