Abstract

The effect of chrome content in chrome tanning liquid on the physical and mechanical properties of leather when using the specially designed leather tanning machine were studied and the leather was characterized by EDS and SEM. The results showed that, considering the chrome content in leather and the physical and mechanical properties of leather, the best chrome content in the chrome tanning liquid was 16g/L. The EDS results showed that the distribution of chrome in leather was relatively uniform. The SEM results showed that the collagen fibre dispersion of leather tanned with the leather tanning machine was better than the leather tanned by drum.
