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