Synthesis of fatliquor from waste bovine fat for use in small scale leather industry
116-120In this study, fatliquor has been
synthesized from waste bovine fat for its use in small scale leather industry.
The physico-chemical properties of bovine fat are determined before sulphation
with sulphuric acid followed by the subsequently neutralization with ammonia to
produce the fatliquor. The fatliquor is subjected to chemical and physical
analyses. The degree of sulphation is found to be 90% and the surface active
groups of the fatliquor are observed in anionic form. The fatliquor has been
applied onto light leather and physical tests are carried out on the fixed
leathers. The results of the physical tests on fixed leather conform to the
standard leather specifications. It is observed that the synthesized fatliquor
could be used as an alternative in leather fixation
