Class Shoe S.R.L.3rd International Conference on Advanced Materials and Systems, ICAMS 2010 -- 16 September 2010 through 18 September 2010 -- Bucharest -- 85353In this research washing and perspiration fastnesses of medical sheepskins produced with different combinations of aluminium triformiade, basic chromium sulphate, polyaldehyde, synthetic and vegetal tanning agents were investigated. It was found that differences of the softness values between the process recipes were statistically significant (P<0.05). It was determined that softness characteristics of leathers after washing and perspiration treatment had improved depending on usage rate of chromium and polyaldehyde. It was also detected that lighter leathers could produced by using more chromium and area loss of leathers after washing and perspiration treatment was minimum level by increasing usage rate of polyaldehyde. Differences of the colour coordinate values between the procedures were found statistically significant (P
