We present the results of an experimental study of the effective thermal conductivity and specific heat capacity of fabrics made from chemical fibers having different structures, in the bulk density range 383-606 kg/m3. We give equations for determining the effective thermal conductivity coefficient and the effective internal surface of the material, obtained on the basis of a macroquantum transfer mechanism. We give an example of a calculation using these equations. We describe and analyze the new parameters: the relaxation coefficients, the temperature and volume form factor for the macrocell. The results obtained for all the studied materials are generalized as a dependence of the thermal conductivity coefficient on a combination of physical constants.
