ABSTRACT:
The present invention relates to a novel leather making process whereby the post-tanning wet operations are done prior to tanning stage itself to make leather in eco-friendly manner in substantially shorter duration. The present process reduces the number of required steps for leather processing and the pollution load generated in comparison to conventional leather processing.
