\* Calculated by the formula: *ϕ = G/hρ*, where *ϕ* is the solid volume fraction; *G* is the fabric weight; *h* is the fabric thickness; and *ρ* is the fiber density [6]. The commonly accepted values of 1.52 g/cm<sup>3</sup> [112], 1.45 g/cm<sup>3</sup> [113,114], 1.5 g/cm<sup>3</sup> [115], 1.45 g/cm<sup>3</sup> [116], 1.31 g/cm<sup>3</sup> [117] and 1.39 g/cm<sup>3</sup> [118,119] were used for the densities of cotton, flax, jute, hemp, wool and polyester fibers, respectively. † Calculated by the formula: *<sup>ϕ</sup>* = 1 <sup>−</sup> *<sup>p</sup>*/100, where *<sup>p</sup>* is the porosity (%) [120]. ‡ Calculated by Equation (4). § Calculated by *M* = 100*R*/(100 + *R*), where *M* and *R* are the moisture content (%) and the moisture regain (%), respectively [121].
