Bating Enzymes

In this final beam-house process, residues of non-collagen protein and other interfibrillary material are removed. This leaves the pelt clean and relaxed, ready for the tanning operation. Traditionally, pancreatic bates have been used, but bacterial products are gaining more and more acceptance. By combining the two types of protease or using SEBate Acid, the tanner gets an excellent bate with synergistic effects which can be applied to all kinds of skin and hide. The desired result of a clean grain with both softness and tightness is achieved in a short time.

Pickled skins and wet-blue stock have become important commodities. A secondary bating is necessary due to nonhomogeneity. For skins as well as double face and fur that have not been limed and bated, a combination of an acid protease and lipase or Acid Bate / SEBate Series from AETL ensures increased evenness, softness and uniformity in the dyeing process. Wetblue intended for shoe uppers is treated with a semi-acid protease combined with a lipase, resulting in improved consistency of the stock.
