The work presented is a continuation of research on the interthread channels of single fabric taking into account the parameters of fabric structure. The stereographic method of threedimensional structure analysis of a single fabric, the method of 3D microscopy of fabric fragments in structural light and analysis of microscopic images of the 4th generation were introduced. Statistical analysis of the air permeability, water vapour resistance and thermal resistance indicators for flat textile products showed significant dependences of these flow rates on channel parameters as well as other fabric parameters. The correlation between the parameters measured and the flow indicators was determined. Very strong correlations of the air permeability indicator were found with the channel clearance area, warp count and approximate channel volume. A strong correlation with the thickness of fabrics was obtained for the water vapour resistance indicator. For heat resistance there was a strong correlation with the diameter of channel inlets. Strong correlations between fabric parameters and channel parameters were obtained for the channel clearance area and approximate channel volume, warp and channel ground area, weft count and fabric thickness, channel inlet diameter, and fabric thickness.
