PicklageLe picklage consiste à faire absorber à la peau en tripe une quantité importante d'acide, en présence de sel neutre (NaCl) pour réprimer le gonflement que provoquerait l'acidité du milieu.

| Résumé : |
In earlier papers, we studied the behaviour in the pickling/tanning processes of hides1,2 and sheepskins3,4 of four commercial non-swelling products. The application of these products yielded a significant reduction in salinity. In the case of sheepskins, the best results in terms of non-swelling capacity, shrinkage temperature, conductivity and Chemical Oxygen Demand of the residual baths corresponded to the pickling treatments carried out at a salinity of 2°Bé with a 2% offer of naphtol 3-6 disulphonic acid, or with a 2% offer of p-hydroxydiphenyl sulphonic acid, or with a 4% offer of polyacrylic acid. |
