| Résumé : |
Tannage experiments of New Zealand lambskins were carried out in different water-immiscible organic solvents : dichloromethane, trichloroethane, trichloroethylene and tetrachloroethylene with different vegetable tannins : sweetened chestnut, mimosa and sulphited quebracho (ATS) have shown, under the conditions of tannage, that according to the amount of water dispersed in the tanning bath (water coming from the pelts), the nature of tannin and the properties of the organic solvent that the tanning process may be compared to a gel emulsion phenomenon which prevents tannin from diffusing into skin. This effect is more marked in presence of quebracho and tetrachloroethylene. However, this emulsion may be avoided by adding a co-solvent (acetone) to the tanning bath. |
