wool fibers are able to accumulate the moisture (from sweat or small rain) fully in the central part (cortex) and simultaneously keep the hydrophobic surface shelves dry, thus offering relative high thermal resistance and dry (warm) contact feeling even with 30–40% moisture in the fabrics
thermal comfort properties of wool fibers and wool fabrics cannot be found in cotton and viscose fabrics, (Oglakcioglu and Marmarali 2010) where the deterioration of their thermal comfort properties with the increasing relative moisture is much stronger and quicker than in the studied woolen fabrics samples. Thus, even in case of wool and wool/PES fabrics subject to some antifelting treatment, like in our case, the thermal comfort properties of the investigated samples exhibited relatively slow decrease of their thermal resistance and relatively slow increase of their thermal contact feeling, when the relative moisture content increases. That is why the woolen fabrics belong to the most comfortable and valuable commercial textile products.
Sure, lazy ass.
