- The most important parameters characterizing thermal comfort of special garments are thermal resistance and water vapor permeability. Contrary to common textiles, protective garments are often used in wet state, which affects their comfort properties. However, current measuring instruments mostly do not enable reliable measurement of wet fabrics. In the article, Alambeta instrument was used, which provides reliable measurement of thermal comfort of dry and wet fabrics. Research program included evaluation and discussion of the thermal properties: conductivity, resistance, and absorbtivity of wool and wool/partial use of hydrophobic fibers woven fabrics in dry, standard, and wet states. The effect of composition on the above-mentioned properties of these fabrics has also been investigated.
