Preparation and Properties of Chrome Tanning Agent from Chrome Sludge

Abstract:

In this study, Regenerated chrome tanning agent is prepared from chrome sludge by hydrogen peroxide oxidation. The regenerated chrome tanning agent was characterized by IR which reveals that organic acid and protein polypeptide combined with chrome have been mostly removed. A small part of organic acid and protein polypeptide, not oxidized, increases the masking effect of the product. The application results show that the shrinkage temperature (Ts) of wet blue leather can reach 100°C and the leather has good feeling of handle and fullness which shows it has same properties with commercial chrome tanning agent.
