For this reason; in last decades, researches on alternative tanning materials which will decrease or replace chromium usage take a great share among the main topics in the area of leather researches. In this research, a newly produced titanium based tanning agent, obtained from processing wastes from the industry of nonferrous metals was used as an alternative to chromium tanning agent. The new titanium tanning agent was experimented with 1%, 2.5%, 5%, 7.5 and 10% dosages. Physical tests and chemical analysis of the produced chromium-free leathers gave comparable results to leathers tanned with basic chromium sulphate. 5% usage of titanium tanning agent was found to be optimal.eninfo:eu-repo/semantics/closedAccessChromium-free leathersTanningTitaniumConference Object147152N/A
