The objective of this study was to evaluate the physicochemical characteristics and mechanical properties of leathers from cobia skin, under different tanning agents (chrome salt; vegetable tannin; synthetic tannin; vegetable + synthetic tannin) in the retanning step. No significant difference in the thickness of cobia leathers was observed. The tanning agents used in retanning did not interfere in the tensile strength determination; however retanned leathers with synthetic tannin showed significantly less resistance to progressive tearing compared to leathers tanned with chromium salts. The withdrawal direction of test bodies has not undergone influence the action of retanning to tear and traction. But, leathers subjected to retanning with vegetable tannin showed increased elasticity in the longitudinal direction (81.89%) and lowest in the transverse (29.0%). Leathers which had better physicochemical results were those prepared with vegetable tannin. Therefore, it is more interesting to the tanning of cobia skins with vegetable tannin.

MNK Publication was founded in 2012 to upholder revolutionary ideas that would advance the research and practice of business and management. Today, we comply with to advance fresh thinking in latest scientific fields where we think we can make a real difference and growth now also including medical and social care, education,management and engineering.
We offers several opportunities for partnership and tie-up with individual, corporate and organizational level. We are working on the open access platform. Editors, authors, readers, librarians and conference organizer can work together. We are giving open opportunities to all. Our team is always willing to work and collaborate to promote open access publication.
Our Journals provide one of the strongest International open access platform for research communities. Our conference proceeding services provide conference organizers a privileged platform for publishing extended conference papers as journal publications. It is deliberated to disseminate scientific research and to establish long term International collaborations and partnerships with academic communities and conference organizers.
