As a basis to improve fabrics of sports wears for athletics with much perspiration, frictional behaviors between pigskin and commercially available fifteen sports wear fabrics were measured under dry and wet conditions. The static and dynamic friction coefficients were increased linearly with the water contents of the fabrics up 300%. Those two coefficients under wet condition were found to be linearly correlated with the corresponding coefficients under dry condition with some exceptions for woven fabrics. Distinct differences were observed in the coefficients between knitted and woven fabrics and between cotton and polyester fabrics. The conclusions obtained are as follows. 1) For all of the sample fabrics, the water content increases static and dynamic friction coefficients linearly. 2) These two coefficients are from 0.71-1.02 and 0.51-0.73, respectively under dry condition. The coefficients increase by ca. 30% under 100% water content. 3) the increases of the two coefficients under wet condition are larger for woven fabrics than for knitted ones and also for cotton fabrics than for polyester ones.
