Abstract

Fleshings obtained from the liming process were hydrolysed with a proteolytic enzyme and further broken down to the amino acid level before being used to prepare the corresponding aldehyde, which was used as a crosslinking agent.

In the present study the cross-linking agent developed was used to tan the delimed pelt. Subsequently, the leather obtained was tanned with wattle extract at various levels and the combination effect was studied. The tanning studies carried out using the cross-linking agent were discussed in detail in Part I of the paper. Details of the application of the cross-linker aldehyde and its results on pelts as well as with chrome tannage are described in Part 1 of this paper. (J. Soc. Leather Technol. Chem., 2005, 89 (1), 18.) The combination tanning studies with wattle extract at various levels are discussed in this part.
