The benefits of adequate soaking are sometimes overlooked in the rush to productivity. Removal of molecular species, which hinder uniform distribution of process chemicals, is a key objective. TFL stresses the importance of the choice of auxiliary and careful adjustment of process conditions.
Excessive draw in the wet-blue from fresh raw material is often caused by inadequate soaking - sometimes from the misguided idea that fresh hides / skins do not require soaking or require less soaking.
Non - structured proteins in the skin need to be removed if liming is to be efficient and soft mellow leathers produced. These non-structured proteins are partly broken down by salting but in the case of fresh material remain strongly intact.
Good Practice: Soak well using a biocide ARACIT together with suitable surfactant BORRON and enzyme soaking agent PELLVIT.
