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<0.05). It was determined that colour characteristics of leathers changed depending on tanning agents and leathers had been lighter colour when the ratio of aluminium increases.eninfo:eu-repo/semantics/closedAccessMedical sheepskinPerspiration fastnessWashing fastnessConference Object2126N/A
