Abstract

A new chrome free tanning system of rare earth (RE)-THPS has been developed in this study. It has been proved by UV spectrum that THPS and RE (CeCl 3) can coordinate under certain conditions. The influence of CeCl 3 and THPS's ratio, pH and ligands on the shrinkage temperature (Ts) was studied. Higher T s was obtained while the tannage was processed in the sequence of THPS followed by CeCl 3. The alkaline pH should be controlled between 5.5 and 6.0 to give ideal tanning effect. It was also found that employing of 0.5% tartaric acid in this combination tanning system can give high Ts of 89°C.
