Frictional sounds of 8 vapor permeable water repellent fabrics by sound generator were recorded and analyzed through FFT fast Fourier transform analysis. The frictional Sounds were quantified by calculating level pressure of total sound(LPT), the level range(${Delta}L$) and the frequency difference(${Delta}f$). Mechanical properties were measured by KES-FB. LPT values of specimens finished wet coating were higher than those of other kinds of finishing. ${Delta}L$ values of specimens laminated were highest. Absolute values of ${Delta}f$ were high in the cire finished and laminated specimens. Values for bending rigidity, shear stiffness and energy required for the compression of coated specimens increased compared with the cire finished and laminated specimens. Laminated specimens had high values of frictional coefficient and low values of surface roughness. Relationship between frictional sounds and mechanical properties analysed by use of correlation coefficients and stepwise regression. LPT showed significant correlation with elongation, tensile energy, geometrical roughness, weight and thickness. ${Delta}L$ was highly correlated with tensile linearity, frictional coefficient, and ${Delta}f$ with tensile linearity, weight and thickness. LPT were revealed to be explained by elongation and weight. ${Delta}L$were predicted by tensile linearity, and ${Delta}f$ by tensile linearity and thickness.
