Effect of processing agents on physical properties on aniline-type leathers such as wet blue, crust leather, and finished leather has been investigated. These leathers were manufactured from pelts obtained by the chemical, the enzyme, and the bio-tech treatment. There was no difference in physical properties between crust leather and finished leather. All finished leathers with the three treatments were satisfied with the Korean Industrial Standard like a tensile strength of $1.2kg_f/mm^2$, an elongation of 30%, a tear strength of $3.0kg_f/mm$, a grain crack weight of $15kg_f$, and a $Cr_2O_3$ content of 2.5%. In peculiar, application of the bio-tech treatment gave the best leather. This improvement of physical quality could be explained by the results of SEM and image analyser.
