| Abstract: | Thermal comfort is condition of an organism, when there is no sweating and the mean skin temperature is in the range from 32 to 34?°C (Hes, Measurement of comfort, What can textile III, 2009). Thermal comfort is closely connected with the following characteristics: thermal resistivity and thermal conductivity. Related properties are: resistance against the penetration of water vapor, air permeability, and porosity. The thermal resistivity R (W?1?K?m2) and thermal conductivity K (W?K?1?m?1) of knitted fabrics containing PP fiber were measured. Measurements were realized on three different types of devices. The experimental results were compared with simple mechanistic model for prediction of thermal conductivity K for textile structures. |
